Sensors are available in plastic and stainless steel, and special NAMUR versions enable use in hazardous areas.

thru beam sensors

Extremely long sensing ranges and high signal strengths can be achieved with P&F’s thru-beam sensors because the light emitted from the emitter reaches the receiver directly. 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

P&F retro-reflective sensors provide a longer sensing range when compared to diffused sensors. In some units a visible red LED is used which aids in the installation and alignment of the reflector. A polarizing filter enables the trouble-free detection of glossy and high reflective objects.

Their clear object detection sensor is a special retro-reflective mode photoelectric sensor that detects clear objects ordinary retro-reflective sensors may not.

diffuse mode sensors

Excellent for part presence and product height applications, P&F’s diffuse mode sensors, also known as proximity sensors, are very useful in space restrictive locations. Available in a variety of sensing modes including; background suppression, foreground suppression and background evaluation.

fiber optic sensors

P&F fiber optic sensors provide a sensing solution for applications involving small targets or unfavorable conditions. Fiber optic sensors & cables can be used in much smaller areas, in harsher environments, at temperature extremes that ordinary photoelectric sensors could not withstand.

These fiber optic sensors come in a variety of sizes and shapes ranging from small DIN-rail mountable units to 18mm cylindrical housings to full-size limit switch housings. The sensors are available with numerous outputs, digital displays and a wide assortment of cables to choose from.

contrast sensors

P&F contrast sensors are characterized by a low contrast resolution, a high degree of switching reliability when differences in contrast are minimal, short response times, and insensitivity to fluctuations in height and angle on the material web. These sensors are used for precise object positioning in printing machines, packaging plants, and labeling machines in the food, beverage, and pharmaceutical industries.

color sensors

P&F color sensors operate on multicolored backgrounds with an exceptional degree of reliability. The sensor periodically scans the target material on the R, G, B color channels in order to detect the taught in color. Three different colors can be taught in and recognized in parallel. Color sensors are used to identify minute color variations for sorting, positioning, and quality control.

distance sensors

P&F offers a complete sensor family based entirely on the superior Pulse Ranging Technology (PRT). The modern Pulse Ranging Technology (PRT) delivers better parameters at a lower cost. These sensors offer long range, accuracy and insensitivity to extraneous.

Distance sensors are available in several formats including’ 2-D laser scanners, multi-ray LED scanner, also known as 2-D LIDAR sensor, multi-layer 3-D LIDAR sensors, and DuraBeam laser technology.

retro-reflective ultrasonic sensors

P&F offers retroreflective and diffuse mode ultrasonic sensors. With diffuse mode sensors, the runtime of the ultrasonic signal from the sensor to the object is evaluated. Tthe measured object distance is provided either as an analog signal, a binary switching signal, or in digital form via an interface.

In retroreflective mode, the ultrasonic signal is constantly reflected by a permanently installed reflector. Any change to the ultrasonic signal caused by an object located between the sensor and reference reflector results in an output change.

thru-beam ultrasonic sensors

P&F thru-beam ultrasonic sensors use separate emitter and receiver transducers. Their significantly higher switching frequency also makes thru-beam sensors suitable for a wide range of high-speed applications. Other features include; reliable detection of transparent materials, adjustable sensitivity and available stainless steel housings.

double sheet sensors

P&F double sheer sensors quickly and reliably detect a double sheet or a splice in the material. Thin papers with a density of 10 g/m² up to cardboard with a density of 2000 g/m² can be monitored as well as the detection of thin plastic or metal films. An automatic adjustment for the switching thresholds allow for changing ambient conditions.

inclination sensors

Pepperl+Fuchs’ inclination sensors reliably detect inclination angles in factory automation and mobile equipment applications. They are an ideal solution for leveling mobile work platforms, for instance. The sensor continuously monitors the platform’s incline and indicates when readjustment is necessary.

acceleration sensors

F99 series acceleration sensors monitor strong vibration and acceleration in plants. This makes them an ideal solution for monitoring a wind turbine installation. When a set mechanical vibration limit is exceeded, the system shuts off to avoid damage.

inertial measurement unit

The F99-Fusion inertial measurement unit has been specially developed for inclination and acceleration detection in dynamic applications. It provides 360° measurement along six axes. An intelligent Sensor Fusion Algorithm compensates for external acceleration and opens up new possibilities.

In positioning tasks in particular, the absolute encoders relieve the controller of computation tasks and keep costs down by eliminating the need for additional input components. The Pepperl+Fuchs rotary encoder portfolio includes a varied range of current interfaces for absolute encoders including Parallel, DeviceNet, Ethernet, PROFIBUS, PROFINET and AS-interface.

incremental encoders

P&F incremental rotary encoders supply a certain number of pulses for each shaft revolution. Speed is measured by counting the pulses for a period of time.Dual channel quadrature output encoders feature two signal outputs that are 900 out of phase with each other. This permits the controller to determine direction of rotation and perform bi-directional positioning tasks.

In addition, three-channel incremental encoders have a third signal channel (known as “zero”, or reference, signal) that provides a single pulse for each revolution.

cable pulls

P&F cable pulls enable a rotary encoder to measure linear motion by providing a cable that is pulled in a straight line by the application.
