Features
Retro-reflective area sensor with 6 light beams in standard photoelectric- sensor enclosure Connection compatibly replaces single beam photoelectric sensor Reliable detection of the front edge of the object irrespective of its shape and position Constant object detection from 12 mm within the entire detection area Reliable detection of all surfaces irrespective of the object texture Switches when contrast difference 10% Bright, highly visible transmitter beams, guarantee convenient alignment of the sensor Product information The RLG28 retro-refl ective area sensor contains several transmitters and receivers in one housing and with a reflector positioned opposite forms a 60 mm detection area over a sensing range of 0,6 m. When the light beams are interrupted by an object, the switching function is triggered. The smallest detectable object size is 12 mm. The RLG28 switches at a 10% contrast difference with a response time of 1 ms. An intelligent gain control compensates for effects such as dirt, misalignment, and temperature.
