Through-beam photoelectric sensor
VE/VR
DELTA
The emitter VE unit emits a high intensity, visible beam of modulated red light. This beam is detected by the photosensitive diode fitted with an optical filter and whose signal is processed by the incorporated circuitry of the receiver VR. The output changes state depending on whether the modulated beam is interrupted or not.
Beam modulation, special optical filter and automatic correction make the sensor insensitive to ambient light.
