Product Information

Full details

This guide is for industrial safety professionals and machine operators who need reliable emergency stop functionality. The Eaton M22 Series Mushroom Push Button offers a robust, IP67-rated solution for immediate machine shutdown, with a simple twist-to-release mechanism. A key consideration is its single STOP function, meaning it's designed solely for emergency stops and not for general operational control.

FAQs

What is the primary function of this button?

This button is exclusively designed for emergency STOP functions, allowing for immediate shutdown of machinery in hazardous situations.

How is the button reset after activation?

The button is reset by twisting it. The direction of the twist (usually clockwise) may vary slightly based on the specific contact block installed, but 'twist-to-release' is the standard mechanism.

Does this product include the electrical contact block?

No, the Eaton M22 Series Mushroom Push Button actuator is sold separately from its corresponding contact block. You will need to purchase a suitable latching contact block for the STOP function.

What does the IP67/IP69K rating mean?

IP67 means the button is protected against dust ingress and can withstand immersion in water up to 1 meter for 30 minutes. IP69K provides protection against high-pressure, high-temperature spray downs, making it suitable for frequent washdowns.

Can this button be used for normal ON/OFF operations?

No, this button is specifically designed and intended for emergency STOP functions only. It features a latching mechanism that is not suitable for regular operational control.

What is the required hole size for mounting?

The button requires a standard 22.5mm diameter hole for mounting in control panels.

Troubleshooting

Button does not reset after twisting

Check if the internal mechanism is obstructed or damaged. Ensure the correct type of latching contact block is properly seated.

Machine does not stop when button is pressed

Verify that the contact block is correctly installed and wired. Check the continuity of the safety circuit and the wiring connections to the contact block.

Button feels loose or wobbly

Ensure the mounting nut or locking mechanism on the back of the actuator is tightened securely to the control panel.

IP67/IP69K protection is compromised

Inspect the sealing O-ring and the mounting surface for damage. Re-tighten the mounting securely if necessary, or replace the seal if damaged.

Pros and Cons

Pros

  • High level of protection against dust and water (IP67/IP69K).
  • Intuitive twist-to-release reset for quick operational recovery.
  • Large, prominent mushroom head for fast and accessible emergency activation.
  • Designed specifically for critical emergency stop functions, enhancing safety.
  • Standard 22.5mm mounting size for broad compatibility with control panels.

Cons

  • Limited to a single STOP function; cannot be used for other control operations.
  • Requires a separate contact block for electrical switching (not included).
  • Twist-release mechanism may require specific user training to ensure correct operation.

Setup, Compatibility & Care

Setup:

  1. Ensure the control panel has a 22.5mm diameter mounting hole.
  2. Mount the button actuator into the panel, securing it according to the panel's design (typically with a locking ring or screws).
  3. Connect the appropriate Eaton M22 series contact block (sold separately) to the rear of the actuator. This button requires a contact block with a latching switching function.
  4. Wire the contact block into your machine's safety circuit according to electrical schematics and safety standards.

Compatibility:

  • Designed for use with Eaton M22 series control components.
  • Requires a compatible latching contact block for the STOP function.
  • Suitable for panels requiring a 22.5mm mounting diameter.

Care:

  • Clean the exterior with a soft, damp cloth. Avoid abrasive cleaners or solvents.
  • Periodically check that the button actuates smoothly and the twist-to-release mechanism functions correctly.
  • Verify the IP rating seal is intact if the unit has been removed and reinstalled.
