Schmersal CST180-2 is a coded safety switch with a trapped-key interlock designed to secure access to industrial machinery by locking the guard and requiring the correct key to release the interlock before the door can be opened. The CST180-2 KPL variant corresponds to Schmersal part number 101179574, representing the CST 180-2 configuration offered by Schmersal. Used with compatible actuators and safety circuits in guard-locking applications, it helps meet machine-safety requirements by ensuring that a hazardous state cannot be left unchecked when the access door is open.
