CO2 Impact

By purchasing a refurbished or surplus part like this Eaton M22-K01, you are actively contributing to a more sustainable circular economy. Reusing this component avoids the production of a new one, saving an estimated 1.0 kg of CO2. This saving is comparable to the emissions from driving a standard car for 5 kilometers.

FAQ

What is the difference between the M22-K01 and the M22-K10?

Answer: The last two digits indicate the contact configuration. The M22-K01 has one normally closed (NC) contact and zero normally open contacts. Conversely, the M22-K10 has one normally open (NO) contact and zero normally closed contacts. The actuator color also differs, with red typically indicating NC (K01) and green indicating NO (K10).

Can I stack multiple M22-K01 contact blocks on a single M22 pushbutton actuator?

Answer: Yes, the Eaton M22 series is modular. You can stack up to six contact elements in total on a single M22 operator head, allowing for complex circuit control from one button.

What are Cage Clamp terminals and what is their advantage?

Answer: Cage Clamp terminals are a type of screwless connection technology. You insert the stripped wire into an opening and a spring-loaded clamp provides constant, secure pressure. The main advantages are faster installation time, resistance to vibration, and a reliable connection that does not require periodic retightening.
