Baumer FSDM12(Emitter) - FEDM12(Receiver) Series Sensors
Detection of objects at a great distance – through beam sensors have the longest ranges.
Monitoring of doors and entrances
Due to the good repeatability throughout the entire range, positioning of objects
Reliable detection of high-gloss objects such as mirrors, wafers or chrome-plated surfaces
Characteristics and advantage
Due to the separated configuration, long ranges with large signal excess gain can be achieved in comparison with equivalent retro-reflective systems.
The clearly defined, consistent active zone permits highly constant repeatability throughout the entire sensing distance.
The switching point is independent of the surface properties of the object.
Technology and operation
The emitter and receiver must be aimed at each other. The narrower the angle of radiation and reception, the more accurately this must be conducted.
A separate emitter sends a light beam to a separate receiver. The sensor switches when the light beam is interrupted. Since light is only traveling in one direction, much larger sensing ranges are possible when compared with equivalent sized retro-reflective sensors.
Through beam sensors are therefore preferred for installations in areas with more bad ambient conditions such as dirt, moisture or dust.
