Tips: Problems of proximity sensor's indicator light
Indicator light has a signal prompt without signal output, or signal light is on without signal changes, or indicator light keeps blinking. All indicate that there is an abnormal condition or bad phenomenon. The reasons are as follows:
- Sensor and device wiring error, working voltage error, equipment short circuit and others lead to damages and breakdown caused by the burning of circuit inside sensor
- Poor connection or unstable short circuit that occurs in the device circuit makes non-destructive damages inside the sensor.
- There is no protection function in sensor itself. Because connection error or short circuit directly makes the sensor not available.
M12 proximity sensor can detect nonmetal (or metal), plastic, water, liquid level and powder height, with small size, long life, cheap price, unshielded type installation, anti-interference ability, 5mm detection distance, manufacturer direct sale.
