  • Details: PIR20/31 sw


    The PIR20 passive infrared scanner enables problem-free detection of people. It detects movement as soon as the temperature differential between an object and its environment is greater than ± 0.5°C. The detection range can be accurately set by means of zoom adjustment and lens apertures. The PIR20 detects people approaching as a door.

Opening Doors Made Easy—ECHO Radar Motion Sensors by Pepprel+Fuchs

Opening Doors Made Easy—ECHO Radar Motion Sensors

The new radar motion sensors from Pepperl+Fuchs enable automatic doors and gates to be opened reliably and cost-effectively. Based on powerful 24 GHz technology with microprocessor control, the ECHO radar sensors detect people and objects even under difficult conditions. Two different versions are available for different applications and areas of use: the standard ECHO-D variant and the basic ECHO-M variant

The Ideal Solution for Every Door

The ECHO-D opening impulse sensor with dual antenna offers all standard functions for the efficient operation of automatic doors. The radar sensor is approved worldwide for the detection of moving objects on automatic doors. Whether cross-traffic suppression, direction detection or slow-motion mode: the ECHO-D can be flexibly configured for a wide range of detection tasks. As a highlight, remote control enables particularly convenient operation. Furthermore, a high level of interference immunity makes the sensor insensitive to environmental influences such as rain, fluorescent lights or vibrations. This ensures smooth operation in outdoor areas without additional protective measures.


The ECHO-D radar motion sensor reliably detects moving objects on swing doors worldwide.

The economical ECHO-M opening impulse sensor is equipped with a mono antenna. This sensor is suitable for basic applications in regions where simple motion detectors are permitted on revolving and sliding doors. From design to manufacturing, Pepperl+Fuchs guarantees compliance with the highest quality standards so that the devices always reliably detect the presence of people and objects.

ECHO Radar Motion Sensors Highlights
  • Opening impulse sensors for reliable detection of persons and objects at automatic doors —with powerful 24 GHz technology
  • Two versions available for different applications and areas of use
  • Increased durability due to solid electronic and mechanical design
  • Quick and easy commissioning by remote control or push buttons and visible angle mark
  • Especially compact housing and customizable color—for discreet integration into any door design
Robust Construction
  • Robust Construction, Discreet Design, Simple Commissioning

    Due to a robust electronic and mechanical design, the ECHO opening impulse sensors impress with high durability and tamper resistance. The solid-state relays provide increased switching frequency compared to mechanical relays, maximizing service life. In addition, the devices can only be opened by trained personnel, protecting them from tampering by passers-by.

    The radar motion sensors are quick and easy to commission: Large, highly visible push buttons allow sensitivity to be set with one hand. The detection field can be changed by simply rotating the antenna horizontally or vertically. A visible angle mark and an acoustic signal provide additional convenience in handling.

    Large push buttons, a rotatable antenna and a visible angle mark—these features make commissioning of the ECHO radar motion sensors particularly easy.

    With their miniature cubic housing, the ECHO sensors can be seamlessly integrated into any door design. Different cover colors allow the sensors to blend discreetly into their surroundings. In addition, the motion sensors offer maximum flexibility during installation: besides wall and ceiling mounting, it is also possible to recess the sensors completely into the ceiling using a ceiling mounting kit. Forglass or steel doors where rear mounting is not an option, two side cable entries can be used. In this way, the opening impulse sensors adapt perfectly to many different installation environments.
