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
Note: The sensor recognizes at the VTH → VTL edge of an external trigger that the external trigger has been input.

Notes: 1. The output transistor has an open collector structure.
•Detection status: Output transistor ON (connected to GND)

2.The status of the external trigger input is as follows:
•Open at the high level
•GND (less than 0.8V) at the low level
