Eaton M22-AK11 Auxiliary Contact Block, 1NO+1NC, Front Mounting, Screw Terminals

An auxiliary contact block from the Eaton M22 series, engineered for reliable signal and control circuit switching with one normally open (NO) and one normally closed (NC) contact. Its front mounting design enables quick, tool-free installation onto compatible M22 pushbuttons and selector switches, while screw terminals provide a secure, maintenance-free connection. With a rated insulation voltage of 500 V AC and an operational current of 6 A at 230 V AC (AC-15), this contact block handles demanding industrial control tasks with ease.

Advantages

The M22-AK11 delivers exceptional durability with a mechanical lifespan exceeding 5 million operations and an electrical lifespan of over 500,000 operations. Its silver alloy contacts guarantee low contact resistance and high switching reliability, even in harsh environments. The IP20 terminal protection safeguards against accidental contact, and the wide operating temperature range from -25°C to +70°C ensures consistent performance in diverse conditions. The compact design integrates seamlessly into control panels, saving valuable space.
