Non-contact safety sensors

4.2.1

Magnetic safety switches (e.g. SICK RE)

The contact symbols in this chapter show the switching status while the switch is
actuated (e.g. while the door is closed).
Magnetic safety switches with equivalent inputs (e.g. SICK RE13, RE27)
Electrical connection: Example from Setting and Monitoring Tool with WS0-XTIO
Connected to test output
Magnetic safety switches with complementary inputs (e.g. SICK RE11, RE21,
RE31, RE300)
Electrical connection: Example from Setting and Monitoring Tool with WS0-XTIO
Connected to test output
Function
Testing
Series connection/
cascading
Discrepancy time
Further information is available in the manuals of the SICK magnetic safety switches
or in the manuals of devices used.
4.2.2

Inductive safety switches (e.g. SICK IN4000 and IN4000 Direct)

Electrical connection: Example from Setting and Monitoring Tool with WS0-XTIO
IN4000
IN4000 Direct
(with OSSD)
Function
Testing
Series connection/
cascading
Further information is available in the manuals of the SICK inductive safety switches or
in the manuals of devices used.
Possible
Possible; observe the max. line resistance of 100 Ω and the
correct setting of the test impulse time
Default: 1.5 s. See Setting and Monitoring Tool.
Necessary on IN4000
IN4000 direct cannot be cascaded
IN4000: up to 6 sensors per input
Max. off-on delay of the cascade 10 ms (otherwise the test gap
will lead to switching off)
Observe the max. line resistance of 100 Ω and the correct setting
of the test pulse time
Channel 1: Contact between X1 and I1
Channel 2: Contact between X2 and I2
NC contact between X1 and I3
NO contact between X2 and I4
Notes
Test input TE (IN4000) at X1
Output A (IN4000) at I1
OSSD1 (IN4000) at I3
OSSD2 (IN4000) at I4
