<In case of setting the external device monitoring function to disabled>
- In order to disable the external device monitoring function, connect the auxiliary output and external device monitoring input. At such times, do not connect a load to the auxiliary output.
Note: |
Unused wires must be insulated to ensure that they do not come into contact with wires already in use. |

Test input Open: Emission halt Vs to Vs – 2.5 V (sink current 5 mA or less): Emission (Note 2) |
Notes:
1) |
Unused wires must be insulated to ensure that they do not come into contact with wires already in use. |
2) |
Vs is the applying supply voltage. |

SF-C11
SF2B series wiring diagram (Control category 2)
For NPN output (plus ground) |
- Set the safety light curtain input polarity selection switch to the NPN side and ground the + side.
Notes:
1) |
The above 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 occurs when the test (TEST) button is open, and emission occurs when the test (TEST) button is short-circuited. If not using the test (TEST) button, short-circuit T1 and T2. However, use a test rod or similar to interrupt the light in order to carry out self-diagnosis separately. |
For PNP output (minus ground) |
- Set the safety light curtain input polarity selection switch to the PNP side and ground the 0 V line.
Notes:
1) |
The above 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. |

Be sure to use the following mating cables when connecting SF-C11 to
SF2B series.
SF2B-CB05 (cable length: 0.5 m 1.640 ft)
SF2B-CB5 (cable length: 5 m 16.404 ft)
SF2B-CB10 (cable length: 10 m 32.808 ft)
SFB-CCJ10E (for emitter, cable length: 10 m 32.808 ft)
SFB-CCJ10D (for receiver, cable length: 10 m 32.808 ft)

SF-C13
SF2B series wiring diagram (Control category 2)
- Connect the safety light curtain control outputs OSSD 1 and OSSD 2 to S4 and S2 respectively and ground the + 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. |
- Connect the safety light curtain control outputs OSSD 1 and OSSD 2 to S1 and S2 respectively.
Notes:
