NKK Switches High Security Keylock CKL12BTW01-044

The CKL series is a high-security keylock with a 19mm bushing, available in flat or tubular key styles, designed for applications requiring rugged construction and high reliability. It features a vertically rotating switching mechanism with self-cleaning silver contacts, rated for 3A at 250V AC resistive load, and a mechanical life of 30,000 cycles. Contact resistance is 20 milliohms maximum, insulation resistance is 1,000 megohms minimum at 500V DC, and dielectric strength is 1,500V AC between contacts and case. The housing is zinc alloy with chrome plating, and the base is LCP. Operating temperature ranges from -25°C to +70°C. Mounting torque is 1.5 Nm maximum. The switch has a 90° angular throw for 2-position operation and a break-before-make contact timing. Terminals are solder lugs with epoxy sealing. Electrostatic discharge protection is not specified for CKL models.
