Why Choose the Ilme CKF03 Female Insert?

The Ilme CKF03 is a compact female multipole connector insert with 3 poles plus protective earth, designed for dependable electrical connections in industrial machinery, automation equipment and control systems. Part of the Ilme CK connector series, it uses the compact size 21.21 format and provides screw-terminal termination for straightforward field wiring.

Rated at 10 A, the CKF03 provides three female power or signal contacts together with a dedicated protective earth connection. Its screw-terminal design allows conductors to be securely terminated without specialised crimping equipment, making installation and maintenance practical for machine builders, panel manufacturers and industrial electricians.

The insert is intended for use with compatible Ilme size 21.21 hoods and housings, allowing a complete protected multipole connector assembly to be created. Its compact dimensions make it particularly suitable for machinery and equipment where installation space is restricted but a robust detachable electrical connection is required.
