Optical sensor VISOLUX RL 21-8-800-1419/44
reflection light barrier VISOLUX RL 21-8-800-1419/44 Voltage: 10-30V Optical sensors are another type of proximity sensors that work based on sending and receiving modulated light. Modulated light is pulses with a frequency between 5-30 kHz and the use of modulated light increases the detection range of the sensor and also reduces the effect of ambient light on the sensor.
