SICK Photoelectric Reflex Switch Teach-In WL0-2P431 NEW
SICK Photoelectric Reflex Switch
With the photoelectric reflex switches, the emitted light beam is reflected by a reflector and then received and evaluated by the device.
Polarization filters prevent incorrect operation when reflective objects are detected. Transparent films and shrink-wrap may influence the way in which the reflex photoelectric switches with polarization filters function. Devices with reduced sensitivity solve this problem.
The use if laser diodes allows greater scanning ranges while simultaneously maintaining a high resolution. Focus ranges can be set with high precision.
Photoelectric reflex switches for detecting transparent objects
These reflex photoelectric switches are characterized by their extremely low switching hysteresis. Even slight light attenuation between the sensor and reflector, caused by e.g. glass bottles or even PET bottles, is detected reliably.
A newly developed system check continuously corrects the switching threshold electronically to adapt to the gradual accumulation of dirt, which would otherwise lead to a system failure.
* Red-light emitter LED as alignment aid
* Outputs short-circuit protected
* Sensitivity adjustment using the Teach-In procedure
