  • PNP output type

  • Through-beam type emitter

  • Connector type


    ▪ Turns to Light ON mode when the white wire is connected to +V or not connected and to Dark ON mode when connected to 0 V (for NPN). To use without connecting, disconnect and wrap individually with insulating tape, and do not connect it to any other terminal.
    ▪1 to 4 are connector pin No.


    ▪ When using a switching regulator for the power supply, be sure to ground the frame ground terminal.
    ▪ Because wiring sensor wires with high-voltage wires or power supply wires can result in malfunctions due to noise, which can cause damage, make sure to wire separately.
    ▪ Avoid using the transient state while the power is on (approx. 100 ms).
    ▪ The connector direction is fixed as the drawing below when you use L-shaped connector cable. Be aware that rotation is not possible.
