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.
HOW TO USE
• Wiring diagram of connector
NPN output type
(No connection)
PNP output type
(No connection)
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)
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.
3. 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.
