Schmersal CSS8-180-2PD-M-ST Coded Safety Switch

Schmersal CSS 8-180-2P+D-M-ST is a coded, non-contact safety switch with an integrated M12 connector (8-pin) designed for series-wiring in safety circuits and intended for machine guarding in tight, multi-point installations, with a coded magnetic profile that enhances reliability in chained configurations. The 101209595 variant provides two short-circuit-tested PNP safety outputs and a diagnostic output, plus an LED indicator, all in a thermoplastic IP65 enclosure for robust industrial use. It operates from a 24 V DC supply, tolerates -25 to +60 C, supports a maximum sensor-chain length of 200 meters, and enables self-testing of up to 16 sensors in a single series to ensure continuous safety monitoring across complex guard networks. The ST variant offers a connector-equipped solution that simplifies installation and wiring in multi-point safety configurations, while its high switching point repeatability and misalignment resistance help maintain consistent safety performance in demanding production environments. Typical applications include guarding access to automated machinery, doors and gates on production lines, and other safety-critical interlock points where reliable, coded signaling and diagnostics are essential.
