M22-D-G

1. Overview

The Eaton M22-D-G (article number 216596, EAN 4015082165963) is a non-illuminated, flush-mount, momentary pushbutton actuator in the RMQ-Titan M22 22.5mm modular control system. It features a green actuator cap and a titanium-colored (silver-gray) plastic bezel. "RMQ-Titan" is the series family brand name; the orderable part number is M22-D-G, not "RMQ-M22-D-G." Originally produced by Moeller (Klöckner-Moeller), the product was rebranded Eaton after Eaton's acquisition of Moeller, and is also sold under the Eaton Cutler-Hammer brand in North America. The M22 platform is a heavy-duty industrial modular pilot device system with a wide ecosystem of actuators, contact blocks, LED elements, and mounting accessories.

Important: The M22-D-G is an actuator and bezel only. It does not include electrical contacts and cannot switch a circuit on its own. A separate M22-A fixing adapter and at least one contact block (M22-K10 for normally open, M22-K01 for normally closed) must be added to form a functional switch. Up to 6 contact blocks can be stacked on a single actuator.

2. User Sentiment

No dedicated user review forums or community threads specific to the M22-D-G were found in web searches. The product's long-standing availability across a very broad distributor network (RS Components, Newark, Conrad, Automation24, TME, and many regional distributors across Europe, Asia-Pacific, and the Americas) suggests it is a well-established industry staple with stable demand. One UK distributor (Rapid Online) listed it as discontinued at their outlet, though Eaton continues to list it as active and it remains broadly stocked. The product's 13,500,000 mechanical operation rating and IP69K certification position it as a high-durability choice compared to standard industrial pushbuttons, and its modular snap-on assembly is noted as reducing cabinet assembly time.

3. Real-World Applications

The M22-D-G is suited for industrial control panels, machine tool control stations, factory automation lines, and process control equipment. Its IP66/IP67/IP69K rating makes it particularly appropriate for food and beverage processing, dairy, pharmaceutical, and chemical industries where high-pressure washdown cleaning is routine. The flush actuator profile reduces the risk of accidental activation in crowded panel environments. It is used in both panel-mount configurations and in Eaton's M22-I1 plastic surface-mount enclosure (giving complete control stations such as the M22-D-G-X1/KC10/I). Operating temperature range of -25°C to +70°C covers outdoor and refrigerated-facility installations.

5. Ordering & Compatibility

The M22-D-G (216596) is an actuator-only component. To build a functional pushbutton switch, order the following separately:

• M22-A — fixing adapter (mandatory; mounts actuator to panel and provides rear housing for contact blocks)
• M22-K10 — normally open (NO) contact block
• M22-K01 — normally closed (NC) contact block
• Other contact blocks: M22-K11 (1NO+1NC), M22-K20 (2NO), M22-K02 (2NC), M22-K21, M22-K12

Automation24 offers a convenience bundle set (M22-D-G/-A/-K10) pre-combining the actuator, adapter, and one NO contact block. Pre-assembled complete devices are also available under part numbers like M22-D-G-K10 (actuator with K10 attached) or M22-D-G-K11. The metal-bezel equivalent is M22M-D-G; the stainless-steel slim variant is M22S-D-G (article 216597 — different PN).

Indicative pricing: €2.76–€8.39 (Europe, ex-VAT, varies by distributor); ~USD $9.38 (US, some retailers); ~INR 1,110 ex-GST (India). Available through RS Components, Newark, Conrad, Automation24, Shortec, Elstila, and many industrial distributors worldwide.

6. Known Issues

No significant issues or quality complaints were found in available sources. One UK distributor (Rapid Online) lists the M22-D-G as discontinued at their outlet, though the product remains current and actively stocked at Eaton and the majority of global distributors — this likely reflects that retailer's own sourcing decision. Practitioners should note that the M22-D-G is an actuator-only part and ordering it without the M22-A adapter and a contact block is a common purchasing mistake; Automation24's set bundles help mitigate this. The "RMQ" prefix in some catalog slugs and older Moeller documentation is a series label, not part of the orderable PN — searching for "RMQ-M22-D-G" may return fewer or muddied results; the correct search term is M22-D-G or article 216596.
