M22-DL-B

1. Overview

The Eaton M22-DL-B is a blue illuminated flush-mount momentary pushbutton actuator belonging to the Eaton (Moeller) M22 RMQ-Titan modular pushbutton family. It carries Eaton article number 216931 (EAN 4015082169312) and is manufactured in Germany. The M22 series is Eaton's industrial-grade IEC 22.5mm pushbutton platform, distinguished by its modular snap-together construction that allows field assembly of actuators, LED elements, contact blocks, and mounting adapters. The "-DL-B" suffix decodes as: D = flush (flat) pushbutton, L = illuminated, B = blue lens/button color; the bezel is titanium-colored plastic (not chrome metal — the chrome-bezel variant is the M22M-DL-B from the M22M metal series).

2. User Sentiment

No forum or community review sentiment was found for this product specifically. Distributor and technical sources universally describe it as a reliable, industry-standard industrial control component. The modular M22 platform is praised for simplifying inventory stocking and enabling on-the-job customization without pre-built configurations. The product is listed as discontinued by at least one distributor (OnlineComponents) though it remains available from 18+ distributors worldwide (per Octopart), and complete pre-assembled kit variants (blister packs) continue to be listed actively by Eaton.

3. Real-World Applications

The M22-DL-B is used in machine control panels, industrial control stations, and operator interfaces across a broad range of industries. Real-world assembly configurations with 1NO (M22-K10) or 1NC (M22-K01) contact blocks cover machine tool functions, conveyor controls, and process equipment. Distributor applications cited include stop signals on public transit vehicles, industrial process control, and general factory automation. The -25°C to +70°C operating temperature range and IP67/IP69K rating make it suitable for washdown environments and outdoor enclosures (NEMA 4X, 13).

5. Ordering & Compatibility

The M22-DL-B is sold as the actuator/lens element only; a complete functional pushbutton requires: (1) M22-DL-B actuator, (2) M22-A mounting adapter, (3) an LED element (M22-LED-B for 12–30V or M22-LED230-B for 85–264V), and (4) a contact block (M22-K10 for NO, M22-K01 for NC). Pre-assembled blister-pack kits include Eaton part 132614 (M22-DL-B-K10LED-BVP, 12–30V) and 132617 (M22-DL-B-K10LED230-BVP, 230V). US street pricing is approximately $12–$15 per actuator (quantity 5–25+); European pricing is approximately €15.33 (Netherlands). Available from 18+ global distributors including DigiKey, Newark, RS Components, TME, Grainger, Automation24, Kempston Controls, and Farnell. The yellow sibling is M22-DL-Y (NSN 5930-01-569-6748); the metal-bezel blue variant is M22M-DL-B-K11-B.

6. Known Issues

At least one distributor (OnlineComponents) flags the M22-DL-B as "discontinued" though it remains widely stocked globally and Eaton continues to list complete kit variants (blister packs) with updated part numbers. The actuator-only nature of the M22-DL-B is a common sourcing confusion — buyers must separately specify and purchase LED elements and contact blocks, which are not included. No electrical or reliability issues were reported in available sources.
