Wiring diagram of SF-C11 and SF4B / SF4B-G series or SF2B series (Control Category 4 or 2)

For PNP output (minus ground)

Set the safety light curtain input polarity selection switch to the PNP side and ground the 0 V line.

Wiring diagram of SF-C11 and SF4B / SF4B-G series or SF2B series (Control Category 4 or 2)

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, in case of SF2B series, use a test rod or similar to interrupt the light in order to carry out self-diagnosis separately.

For NPN output (plus ground)

In the above diagram, set the safety light curtain input polarity selection switch to the NPN side and ground the + side.

When connecting the SF-C11 to the safety light curtains, make sure to use the 8-core connection cable with a connector. Refer to the SF4B / SF4B-G series and SF2B series pages for details. SFB-CB□, SF2B-CB□, SFB-CCJ10□

For PNP output (minus ground)

Wiring diagram of SF-C12 and SF4B series (Control category 4)

Set the two safety light curtain input polarity selection switches to the PNP side and connect the F.G. terminal to the 0 V line.

Note:	The above diagram is when using manual reset. If automatic reset is used, connect a normal close-type pushbutton switch between T1 and T2 and leave between X1 and X2 open.

For NPN output (plus ground)

In the above diagram, set the two safety light curtain input polarity selection switches to the NPN side and connect the F.G. terminal to the + side.

When connecting the SF-C12 to the safety light curtains, make sure to use the 12-core connection cable with a connector.
Refer to the SF4B / SF4B-G series pages for details.

For PNP output (minus ground)

Set the output 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 X12 and X22, and connect them to X13 and X23 as shown by the dotted lines. In this case, a reset (RESET) button is not needed. Terminals X31 to X32 are for manual reset only.
2)	Use a momentary-type switch for the reset (RESET) button.

For NPN output (plus ground)

Set the output polarity selection switch to the NPN side and ground the + side of the power supply input.

Notes: 1)	The left diagram is when using manual reset. If automatic reset is used, disconnect the lead from X12 and X22, and connect them to X13 and X23 as shown by the dotted lines. In this case, a reset (RESET) button is not needed. Terminals X31 to X32 are for manual reset only.
2)	Use a momentary-type switch for the reset (RESET) button.

・	When connecting the SF-C14EX to the safety light curtains, make sure to use the following connecting cable. SFB-CB05-EX (Cable length: 0.5 m 1.640 ft) SFB-CB5-EX (Cable length: 5 m 16.404 ft) SFB-CB10-EX (Cable length: 10 m 32.808 ft)
・	If the NO (Normally Open) contact switch is used as a muting sensor,wire it as shown in the figure below.
・	If the emergency stop switch is not used, short-circuit between the terminals S11 to S12 and S21 to S22 directly.
