Notes: 1. The thin short type is only available for 5V DC.

2.The ratio between the 4 operating modes (*a to *d) depends on the external trigger period and detector time, and the current consumption corresponds with this varying ratio.

4.The output transistor is open collector.

The output transistor is turned ON by the sensor detection status and turned OFF by its non-detection status.

Notes: 1. Circuit stability time : Max. 12 ms

2.During the time taken for the circuit to stabilize after the power is turned on, the ON/OFF status of the output transistor is not determined by whether the sensor is in the detection status or non-detection status.
