ABB MKEY8Z Rope Safety Switch Pull Guard 240V 3 Amp

ABB MKEY8Z Rope Safety Switch Pull Guard is a stainless-steel mechanical safety interlock in ABB's MKEY family, designed for rope-activated machine protection along conveyors, presses, and other industrial equipment, where a pull rope provides a controlled, hands-free shutoff. The unit uses a 2NC contact block configuration for safety interlocking and locking functions, delivering two normally closed circuits that help secure access to hazardous zones. In the power-to-unlock variant, typically wired for 24 V DC, the MKEY8Z variant is IP69K protected and built for demanding environments, with a robust mechanical hold rated up to 2000 N and a stainless-steel housing/head option. All MKEY safety switches are supplied with the appropriate standard key (except MKey9), supporting safe operation and authorized release of the interlock during maintenance.
