Product Information

Full details

This Eaton RMQ-Titan pushbutton box is designed for industrial control applications requiring straightforward start/stop functionality. Its key benefit is providing a robust, clear two-command interface (start/stop) with high protection ratings. A potential caveat is its fixed contact configuration and reliance on external power for operation. Key features include dual-color pushbuttons, IP67/IP69K sealing, and compatibility with a wide voltage range.

Extended Product Information

FAQs

What does IP67/IP69K rating mean for this pushbutton box?

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

Can I change the number of NC/NO contacts?

This specific model comes with a fixed configuration of 2 Normally Open and 2 Normally Closed contacts. While the contact blocks themselves can sometimes be replaced with different types, the fundamental count for this unit is set.

What is the purpose of the 'I' and 'O' symbols?

These are standard industrial symbols. 'I' (often illuminated or associated with green) typically signifies 'ON' or 'Start', while 'O' (often illuminated or associated with red) signifies 'OFF' or 'Stop'.

What voltage range does this pushbutton box operate on?

It operates on AC control supply voltages from 115 to 500V (at 50/60Hz) and DC control supply voltages from 24 to 220V.

Is this product suitable for emergency stop applications?

While it features a red 'Stop' button, it is not a certified emergency stop device (which typically requires a mushroom-head actuator and specific safety standards compliance). It can be used as a standard stop button within a larger control system.

How do I install this into my control panel?

The unit requires a standard 22mm diameter hole in your panel. It is then secured from behind using a locking ring or similar mechanism, ensuring a tight seal.

Troubleshooting

Pushbutton does not respond (no start/stop action)

Verify that the correct control supply voltage is applied to the terminals. Check wiring connections for looseness or incorrect placement. Ensure the appropriate contact blocks are correctly installed.

Incorrect contact behavior (e.g., NC contacts not opening)

Confirm the wiring is connected to the correct NO and NC terminals. Check if the corresponding button is stuck in the pressed position or if the contact block is damaged.

Button is difficult to press or stuck

Inspect the button area for debris or obstructions. Clean gently with a damp cloth. If the issue persists, the internal mechanism may be damaged and require replacement.

Unit is exposed to water/dust ingress despite sealing

Check that the enclosure is properly closed and sealed. Inspect the gasket around the mounting cutout and the enclosure seam for damage. Ensure the IP rating is suitable for the specific application's exposure level.

Pros and Cons

Pros

  • Offers clear visual distinction between start and stop functions.
  • Provides a versatile contact configuration (2 NO, 2 NC).
  • High IP rating ensures reliability in dusty or wet environments.
  • Broad voltage range accommodates diverse power systems.
  • Durable construction suitable for industrial settings.

Cons

  • Fixed contact configuration cannot be altered.
  • Requires external power supply for operation.
  • Limited to basic start/stop functions; not suitable for complex control.
  • Plastic enclosure may be less resistant to impact than metal alternatives.
  • Requires a specific 22mm cutout, limiting retrofitting into other sizes without modification.

Setup, Compatibility & Care

Setup:

  1. Panel Mounting: Mount the pushbutton box into a standard 22mm diameter cutout on a control panel.
  2. Wiring: Connect the control supply voltage to the appropriate terminals based on the desired operating voltage (AC or DC) and the configuration of the 2 NO and 2 NC contacts.
  3. Circuit Integration: Wire the NO and NC contacts into your control circuit as required for your specific application (e.g., interlocking, signaling).

Compatibility:

  • Cutout Size: Requires a 22mm mounting hole.
  • Voltage: Compatible with AC (115-500V, 50/60Hz) and DC (24-220V) control circuits.
  • Accessories: Compatible with Eaton M22 series accessories, including contact blocks (e.g., M22-I2-M1).

Care:

  • Cleaning: Clean the exterior with a slightly damp, soft cloth. Avoid using solvents or abrasive cleaners which could damage the plastic enclosure or markings.
  • Inspection: Periodically inspect the buttons and enclosure for any signs of physical damage or wear.
  • Connections: Ensure electrical connections remain clean and secure.
