KL3-SS-RR QC-M23 Guard Locking Safety Switch with Rear Release and 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 3000N to keep medium to large guard doors closed until hazards have been removed. A non-latching manual escape release is provided to enable quick release of the switch lock in case of emergency. The integrated M23 connector reduces installation time, minimizes 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.
