EATON M22-CK01 kontaktný prvok, 1 rozpínací, predná montáž, pružinová svorka

Emergency stop circuits, mode selector stations, and status lamps all rely on precise switching behind the control panel. The EATON M22-CK01 contact element is purpose-built for M22 series pushbuttons and pilot devices, offering a single normally-closed contact in a front-mount package that snaps directly into the actuator. Its spring-cage terminal accelerates wiring and ensures a vibration-proof connection.

Why choose it

Eaton's M22 line is known for modular flexibility and robust engineering. This contact element inherits that heritage, providing consistent switching under industrial temperature extremes. The spring-cage terminal eliminates the need for periodic re-tightening, reducing maintenance across the machine's lifetime. With approvals for international markets, it simplifies panel assembly and keeps your equipment compliant.

Ideal use cases

• Emergency stop circuits in control panels and machinery
• Status feedback for pilot lights and PLC inputs
• Selector switches in motor starter stations
• Automation equipment with front-mounted control devices

Good to know

This contact element is rated for over 5 million mechanical operations, but the electrical load life depends on switching current and voltage. Always derate appropriately for inductive loads. When installing, the spring-cage terminal accepts up to 2.5 mm² conductors; use the correct screwdriver to open the cage and insert the wire without stripping too much insulation. The front mounting design allows quick assembly without special tools, making it a technician-friendly choice for both new builds and retrofits.
