Transponder-Coded Safety Switch CTP/CTA-L1/2-BR
12.2.

Series connection with Y-distributors

The series connection is shown here based on the example of the version with plug connector M12. The switches are con-
nected one behind the other with the aid of pre-assembled connecting cables and Y-distributors. If a safety door is opened
or if a fault occurs on one of the switches, the system shuts down the machine.

12.2.1. Maximum cable lengths

For devices with IMP/IMM inputs, switch chains are permitted up to a maximum overall cable length of 200 m taking into
account the voltage drop as a result of the cable resistance (see table below with example data and case example).
