Compact Type 4 Safety Beam Sensor ST4
I/O Circuit and Wiring diagrams
ST4-C11
In case of PNP output
・Set the output polarity selection switch to the PNP side. |
 |
|
Notes:
1) |
The left diagram is when using manual reset. If automatic reset is used, disconnect the lead from X2 and connect it to X3. In this case, a reset (RESET) button is not needed. |
2) |
Use a momentary-type switch as the reset (RESET) button. |
3) |
Emission halt input is for stopping emission when open, and emitting when short-circuited. If not using the test button, short-circuit T1 and T2. |
KA, KB: |
Force-guided relay or magnetic contactor |
In case of NPN output
・Set the output polarity selection switch to the NPN side. |
