Basic characteristics of safety light curtain sensor

From the role of the light curtain safety device itself, it is known that it is the part that directly contacts the measured object and the window for information input. The basic characteristics of the light curtain sensor refer to the characteristics of the relationship between the sensor’s output and input, which are generally divided into The static characteristics and the static characteristics of the dynamic sensor refer to the static input signal between the output and the input of the infrared curtain sensor.

1. Check whether the optical curtain is firmly fixed on the equipment to be equipped, whether the transmitter and receiver of the light curtain sensor are in the same plane, and the protection area bordered by the transmitter and receiver should be one of the planes rectangle;

　　2, check whether the transmitter and receiver of the light curtain safety barrier are correctly assembled with their respective cables, and whether the cable terminals are accurately and firmly connected to the power supply and control unit;

3. Power on the safety curtain sensor. At this time, the light curtain sensor starts self-checking, synchronization and self-calibration. After about 1 second, the transmitter indicator is stable and the receiver indicator lights are all off, indicating that the light curtain sensor enters the normal working state. .
