Why Choose the Ilme CKSHM04 SQUICH Male Insert?
The Ilme CKSHM04 is a compact male industrial connector insert with 4 poles plus protective earth (4P+PE), featuring Ilme's SQUICH® spring terminal connection without tools. Part of the CKSH series and designed for the size 21.21 format, it provides fast and dependable conductor termination for machinery, automation and industrial control applications.
Rated at 10 A and 400 V, the CKSHM04 has a rated impulse withstand voltage of 4 kV at pollution degree 3. It is also rated at 10 A and 690 V at pollution degree 2, while its SQUICH® terminals accommodate conductors from 0.14 to 2.5 mm², equivalent to AWG 26–14.
The insert uses turned silver-plated male contacts within a self-extinguishing polycarbonate insulating body. With an operating temperature range of -40 to +125 °C, insulation resistance of at least 10 GΩ and a mechanical life of at least 500 mating cycles, the CKSHM04 provides a robust solution for professional industrial connector assemblies.

Fast Tool-Less Industrial Connectivity with SQUICH®
Ilme's SQUICH® technology uses spring terminals to provide fast conductor termination without conventional terminal screws. The CKSHM04 therefore helps reduce wiring time while providing consistent spring-force contact pressure, making it particularly useful for machine builders, panel manufacturers and OEMs producing repeatable industrial assemblies.
The 4P+PE configuration provides four current-carrying male contacts together with a dedicated protective-earth connection. When fitted into a compatible Ilme size 21.21 enclosure, the CKSHM04 forms part of a compact detachable connector system that can achieve high ingress protection levels for demanding industrial installations.
Typical Applications
- Industrial machinery and automation systems.
- Control panel and machine interfaces.
- Motor and actuator connections.
- Industrial power and control wiring.
- Production and process equipment.
- OEM machinery requiring compact 4P+PE connections.
