Retro-Reflex Sensors for Clear Glass Recognition allow for reliable recognition of clear glass and transparent objects. The transmitter and the receiver are integrated into a single housing and a reflector is required. If the light beam between the sensor and the reflector is interrupted by an object, the output is switched. Glossy objects such as mirrors, chrome plated or other reflective surfaces can be reliably recognized thanks to the integrated polarization filter.
This type of sensor adjusts self-dependently. That means that once the desired switching distance is set, the sensor readjusts it automatically if conditions like contamination, temperature or ageing change.
Four sensors are placed in one housing, that are OR-connected. The output switches if one of the light beams is interrupted, so a wider area can be monitored. Also clear glass objects and foils can be detected securely.
Sensor functions can be activated and scanning results can be acquired via the RS-232 interface.
Adjustments are performed with a potentiometer. With Teach-In versions, adjustments are made with the appropriate keys, externally or via the RS-232 interface.
