The compact R100, R101, and R103 series master short-range applications, while the medium-sized R200 and R201 series are perfect for longer-range sensing. This video shows you the specialties of both series as well as sample applications for the R20x series.

The R10x and R20x series combine several photoelectric families of sensors with efficient technologies in one housing style. They differ only in mounting method and housing design. Once you determine how you would like to mount the sensor, you can select the required functions based on the task at hand. This all-round solution provides a unique flexibility and opens up a variety of possible applications.

Pulse Ranging Technology (PRT) is a method developed by Pepperl+Fuchs that allows even large distances to be measured with high precision.

This technology is based on short laser pulses emitted by a powerful light source. A light-sensitive receiver element in the sensor detects the light pulses reflected by the object. The distance to the object is calculated precisely by directly measuring the time of flight of the light. The high energy density of the laser pulses enables long ranges to be achieved and interference to be effectively suppressed.

PRT sensors therefore offer maximum precision in distance measurement—even in demanding environments.

With the R200 distance sensor, Pepperl+Fuchs is integrating Pulse Ranging Technology into the compact design of 15 x 41.7 x 50.6 mm for the first time. This enables high-precision distance measurements where space is limited.

When measuring white objects directly, the R200 with PRT offers a range of 10 m. In the variant with a reflector, distances up to 60 m can even be measured. Find out more about the new distance sensor in this video.

Pepperl+Fuchs' Multipixel Technology (MPT) enables highly reliable and interference-free distance measurement for near-range applications. This technology combines the measuring functionality of conventional distance sensors with the proven triangulation principle.

With this geometric method, an emitter—LED or laser—emits a light beam to the object, which reflects it back. The reflected light beam is then recaptured by a light-sensitive receiver in the sensor, the multipixel array. Depending on the position of the light spot on the receiver, the distance of the object to the sensor is calculated by geometric triangulation. This is done using intelligent software algorithms.

This enables measuring and switching R10x and R20x sensors to precisely measure the position of an object and clearly distinguish it from the background.

Laser sensors are extremely precise, but they are less durable and have a lower temperature range than LED sensors. Pepperl+Fuchs uses the best of both worlds and combines the strengths of LED sensors and laser sensors with its efficient laser technology DuraBeam.

The R10x and R20x series laser sensors ensure an extended service life and provide the user with new possibilities—even at ambient temperatures up to 60° C.

DuraBeam also uses a special beam profile, which reflects a sharply contoured, circular light spot on an object at any time. Sensors equipped with eye-safe DuraBeam laser technology are ideally suited for highly accurate detection and distance measurement of small objects.
