KL3-SS QC-M23 Guard Locking Safety Switch with M23 Quick Connect

The KL3-SS QC-M23 guard-locking safety interlock features a slimline, mirror-polished 316 stainless steel body and a holding force of up to 3000 N, helping keep medium to large guard doors securely closed until hazards have been removed.

The integrated M23 connector reduces installation time, minimises wiring errors, and makes maintenance or replacement faster and more reliable.

The KL3-SS is suitable for applications requiring strict washdown procedures, including high-temperature, high-pressure washing and exposure to corrosive cleaning chemicals.

Body manufactured from mirror-polished 316 grade stainless steel
Holding force up to F1Max 3000 N / 300 kg
Power-to-unlock interlock function
Rotating head with up to 8 actuator entry positions
Ingress protection up to IP69K (connector rated to IP67)
Connectivity via M23 12way male quick connect
