Intrinsic Safety Barriers


Intrinsic safety barriers from Pepperl+Fuchs limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres. This simplifies maintenance and repair of Ex i circuits.

Pepperl+Fuchs offers a variety of intrinsic safety barriers for different requirements. Select between isolated barriers and Zener barriers that ensure safe signal transmission in hazardous areas.

Signal Conditioners


Signal conditioners protect signal transfer between field devices in safe areas and control systems by galvanic isolation of the loop.
Particularly in case of long transmission paths, signal conditioners avoid compensating currents which may occur from ground loops. Signal conditioners also offer effective protection against electromagnetic disturbance or dangerous over voltages on the signal loops.
Depending on the type, signal conditioners offer additional features like limit switching, transformation from field in standard signals, as well as splitting of signals, which means doubling the input signal.

Remote I/O Systems


Modular remote I/O systems transmit process data from safe or explosion hazardous areas by connecting binary and analog sensors and actors to the control system via a bus interface. Remote I/O is the right choice when you want to put I/O modules close to the field devices. Due to the reduced wiring effort, you not only save cables, but also time, money, and work effort. Hence, remote I/O field units can be installed in a decentralized location inside hazardous areas while you easily control and monitor sensors and actors from the control room.
You can connect 4 mA … 20 mA devices to remote I/O, including water flow transmitters, valve positioners, pressure transducers, or temperature transmitters. Devices such as thermocouples, resistance temperature detectors (RTDs), mechanical contacts, and visual or audible alarms may also be connected.
Our remote I/O systems are compatible with network protocols like:
PROFIBUS DP
MODBUS RTU
MODBUS TCP/IP
FOUNDATION Fieldbus H1

HART Interface Solutions

HART Interface Solutions from Pepperl+Fuchs consist of two HART Multiplexer Systems for multiple signal loops and a HART Loop Converter for single loop applications. The Multiplexer is used to connect HART field devices to Asset Management Systems like AMS™ Suite: Intelligent Device Manager from Emerson Process Management. At the heart of HART Interface Solution (HIS), the HART Multiplexer acts like a gateway device, routing communications between the maintenance workstation PC and the HART field devices. It interrogates each HART device, retrieves device information, and stores it in an internal database. This information is made available by the AMS Device Manager or PACTware. The HART Multiplexer also acts as a message coordinator for communication between the maintenance workstation PC and the HART devices. For a single loop solution, the HART Loop Converter allows access to all process variables provided by a field device and transfers them to conventional 4...20 mA loop. This enables it to make use of the hidden measurements done by many field devices and feed them to conventional DCS Systems.

Signal Conditioners


In process engineering plants such as refineries with exposed building parts or extensive water management systems, surge events can cause disastrous consequences: from damage or destruction of expensive components and machines to breakdown of complete automation systems—not including risks to personnel.
Besides these dangerous risks to people and environment, overvoltages are still one of the most common causes of damage in electrical plant engineering. They primarily occur due to lightning strikes or switching operations, but also due to the following causes:
Electrostatic discharge
Brush fire of large electric machines
Fluctuations in power supply
Ground faults / short circuits
Triggering fuses
Parallel installation of energy and information technology control systems
Pepperl+Fuchs‘ surge protection modules reliably divert surges and currents to ground and protect people and machines against possible negative consequences. Our product range provides you with powerful surge protection solutions for various applications. Find devices for signal line protection, supply line protection, fieldbus, and wireless solutions.

Wireless Solutions


WirelessHART networks for process automation
Wireless communication quickly gains relevance in automation applications. For process automation, it is not the amount of data that poses challenges, but the distances to be bridged. Whenever the plant architecture does not allow conventional wiring, values are only accessible through frequent visits to the field.
WirelessHART offers a cost efficient solution. Measured values become available on a regular basis, which leads to increased quality and more economical operation of process plants.
In a WirelessHART based network, every participating device simultaneously works as a signal source and a repeater. Through the routing of the individual signals across the entire network, a wide network structure becomes possible.
WirelessHART products from Pepperl+Fuchs
Pepperl+Fuchs offers several modules to connect sensors to a control system or asset management system with a wireless network. These WirelessHART products support the installation of field devices from different manufacturers without the need for additional wiring effort and costs. A reliable, interference-free communication is established with the following components.

Photoelectric Sensors

Thru-Beam Sensors

The emitter and receiver on thru-beam sensors are aligned opposite one another. The advantage of this is that the light reaches the receiver directly and long detection ranges and high excess gain can therefore be achieved. These sensors are capable of reliably detecting almost any object. The angle of incidence, surface characteristics, color of the object, etc., are irrelevant and do not influence the functional reliability of the sensor.

Retroreflective Sensors

The emitter and receiver are aligned in a housing such that the retroreflective sensors are easy to install. Simply position a reflector on the opposite side and align the sensor with it. The standard version featuring a polarization filter combines the installation benefits offered by the retroreflective system with the reliable detection, even of reflective objects, at long detection ranges. The retroreflective sensors for clear object detection are ideal for reliably detecting transparent objects.

Switching Sensors with Measurement Core Technology

Switching sensors with measurement core technology are based the Multi Pixel Technology (MPT) developed by Pepperl+Fuchs. Thus, multiple operating modes and switching points are easily set up in a single triangulation sensor. These photoelectric sensors can be configured as background suppression sensors, background evaluation sensors, and in window operation mode. Additionally, the sensors are equipped with a standard IO-Link interface which enables users to easily integrate them into versatile applications.

Fiber Optic Sensors

Fiber optic sensors and cables are the perfect solution for applications where the direct mounting of sensors is not possible due to space restrictions, temperature extremes, and so on. Small fiber optic beams are ideal for detecting tiny objects.

Slot and Slot Grid Sensors

With a fast response time, the devices are ideal for detecting tiny objects from long distances. They are frequently used to detect objects on vibrating and oscillating conveyors. Slot grid sensors handle challenging counting and monitoring tasks such as detecting non-guided objects in free fall.

Contrast Sensors and Color Sensors

In the automation of packaging and printing processes, the reliable detection of print and color marks plays a key role in coordinating the various processing steps. Photoelectric contrast sensors are specially designed for such detection tasks.

Light Grids

Light grids are ideal for applications where wider areas need to be monitored. Light grids are much easier to mount, install, and align and are therefore preferred to multiple individual photoelectric sensors. Application areas range from controlling the width, height, and profile of pallets in material handling facilities to detecting position-independent objects, controlling overlap on larger conveyed goods, and monitoring elevator doors.

Distance Sensors

Even the smallest model is suitable for a wide range of measuring and positioning tasks. It operates using laser triangulation and an analog output. All other sensors from the VDM series use Pulse Ranging Technology, offer long sensing ranges, and achieve extremely accurate measurement results. PRT uses high-intensity light pulses to provide a high degree of operating reliability, even under difficult ambient conditions with exposure to ambient light and dust.

Optical Data Couplers

The optical data couplers were designed to establish wireless communication with stock feeders, industrial trucks, automated transportation systems, overhead conveyors and docking stations. Mechanical and problematic RF- and Wi-Fi-based transmissions are avoided as a result. Devices with a variety of operating ranges and transfer rates are available.

Photoelectric Safety Sensors

Personnel protection is becoming increasingly important in automated processes. Wherever machines perform high-risk movements, the relevant health and safety regulations must be observed. Even if the operator is momentarily distracted, shearing, crushing, and impact injuries must be prevented.

Special Sensors

Pepperl+Fuchs developed a number of industry-specific special devices for applications that are functionally not covered by the standard program. The application-specific sensors offer completely new possibilities in optical sensor technology for the user searching for the “right" solution.

Sensors for Automated Accesses and Entrances

Nowadays, it is hard to imagine life without escalators, automatic doors, gates, barriers, and elevators. As if by magic, they open automatically, detect obstacles, and appear to react quite naturally to approaching people and objects.

Photoelectric Sensor Accessories

An extensive selection of accessories complements our photoelectric sensors product line, with application-specific fiber optic cables, mounting brackets, and a broad range of reflectors.

Industrial Vision


Image processing is one of the most crucial and challenging sensor technologies of the future. Until recently, integrating vision sensors into practical applications was difficult and extremely expensive. Today, vision sensors can be implemented in a wide variety of industries and applications, offering cost advantages over standard solutions in difficult sensing environments. The available devices and systems range from barcode imagers to vision sensors and system solutions that are adapted to the application requirements. The complexity of the solution and the cost of integration vary with each use. Each technology has advantages that are best suited for the application at hand. As one of the few suppliers of industrial vision systems, we can accommodate a wide variety of image processing requirements for machine builders as well as for unique system solutions in plant engineering.

Ultrasonic Sensors


In industrial applications, ultrasonic sensors are characterized by their reliability and outstanding versatility. Ultrasonic sensors can be used to solve even the most complex tasks involving object detection or level measurement with millimetre precision, because their measuring method works reliably under almost all conditions.
No other measuring method can be successfully put to use on such a wide scale and in so many different applications. The devices are extremely robust, making them suitable for even the toughest conditions. The sensor surface cleans itself through vibration, and that is not the only reason why the sensor is insensitive to dirt. The physical principle—the propagation of sound—works, with a few exceptions, in practically any environment.
The measuring method employed by ultrasonic sensors has been viewed as an excessively complex technology, and only used as a “last resort” ... as a solution for particularly difficult applications. Those times have long since passed!
Ultrasonic sensors have proven their reliability and endurance in virtually all industrial sectors.

Rotary Encoders


Rotary encoders can be used in all applications that require monitoring rotation rate, speed, acceleration and direction. These sensors can be utilized in many applications found in mechanical engineering, the conveyor industry, material handling and the packaging industry. You are certain to find a suitable rotary encoder for your application from our broad product offering. In automation, rotary encoders are used as sensors for angle, position, speed and acceleration. Linear motion can also be measured through the use of spindles, gear racks, measuring wheels or cable pulls. Rotary encoders convert a mechanical input into electrical signals, which can be processed by counters, tachometers, programmable logic controllers and industrial PCs.

Whether leveling cranes, monitoring front-loader tilt, or controlling elevators—there are many applications for Pepperl+Fuchs’ inclination and acceleration sensors. They ensure precise measurements, even in harsh conditions. An innovative, two-piece mounting concept makes the F99 series extremely robust: a rugged metal mounting bracket provides the sensor module with impact protection and enables quick and easy replacement of the sensor module if needed. Once installed, the bracket can stay in place without need for new adjustment or calibration. With its corrosion-resistant aluminum housing, the one-piece F199 inclination sensor is just as robust and measures inclination from 0 to 360° with ±0.15° accuracy. Our inclination and acceleration portfolio offers sensors for each of your needs.
