KL1-SS QC-M12 Guard Locking Safety Switch with M12 Quick Connect

The KL1-SS QC-M12 guard locking safety interlock features a compact 316 stainless steel body, making it well suited for demanding industrial environments where strength, durability, and corrosion resistance are important. With a holding force of up to 2000N, the KL1-SS is designed to help keep medium to large guard doors securely closed until hazardous movement has stopped or access is safe. Its robust construction makes it ideal for applications where reliable guard locking is required, while the compact design allows it to be fitted to machinery where space may be limited.
