Notes: 1. The output transistor has an open collector structure.
Detection status: Output transistor ON (connected to GND)
Non-detection status: Output transistor OFF (open state)
Notes: 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
Under no circumstances must a high-level voltage be applied.
Notes: 3. In the case of the external trigger type, to maintain the power supply
noise performance, be certain to connect a capacitor (33µF or more) to
the sensor power supply input terminal in order to stabilize the power
supply voltage.
