Eaton M22-AK01 Contact Element 1NC 216503

Contact element for Eaton M22 series pushbuttons and pilot devices, providing one normally closed (NC) contact. This front-fixing element snaps onto compatible actuators without tools, ensuring fast installation and secure retention. Screw terminals accept solid conductors from 0.5 to 2.5 mm² and stranded conductors with ferrules from 0.5 to 1.5 mm².

Advantages

Rated for 500 V AC and 250 V DC, the M22-AK01 handles operational currents up to 6 A (AC-15, 230 V) and 3 A (DC-13, 24 V). Mechanical durability exceeds 5 million operations, while electrical durability exceeds 0.5 million operations. The compact design fits standard 22.5 mm mounting holes and integrates seamlessly with the M22 modular system.

Suitable for

• Industrial control panels and machine interfaces
• Start/stop circuits, emergency stop functions, and status indication
• Applications requiring reliable switching in harsh environments
