B5W-LB series Light Convergent Reflective Sensor Connection without Load (Digital only) Precautions for Correct Use Do not connect the power supply to the Sensor with no load connected, otherwise the internal elements may explode or burn. Always connect a load when wiring. ● Mounting (1) Ambient light may cause the sensor to malfunction. Vcc In such case, mount the sensor at an angle that ambient light does not enter the receiver lens.
