M22-DL-Y

1. Overview

The Eaton (Moeller) M22-DL-Y is an illuminated flush pushbutton actuator from the RMQ-Titan M22 command system, a premium 22.5mm modular industrial operator platform. The "DL" designation decodes as D = flush pushbutton actuator, L = illuminated (with lamp/LED provision); "-Y" = yellow lens. It is an actuator-only component: it provides the mechanical operator and yellow translucent lens cap, but requires a separate LED element (M22-LED-... or M22-FLED-...) for illumination and one or more contact blocks (M22-K10 for 1NO or M22-K01 for 1NC) plus a fixing adapter (M22-A) to form a complete pilot device assembly. Eaton article number is 216929, EAN 4015082169299. The M22-DL-Y carries a chrome-silver titanium-colored plastic bezel (front ring in titanium color, not chrome metal) — the metal bezel variant is M22-DL-Y-... with a metal body; the all-plastic-bezel version is the M22S-DL-Y.

2. User Sentiment

No dedicated forum or end-user review discussions were found for this specific part number in the indexed sources. Distributor descriptions uniformly describe the M22 series as "industrial heavy-duty" and "ergonomically designed," positioning it for demanding automation environments. The 5,000,000 mechanical operation lifespan and IP69K rating are frequently highlighted as key selling points by sellers across multiple countries (US, UK, DE, PL, CZ, CN, JP). The LED illumination life of up to 100,000 hours (noted for complete M22 LED assemblies) is cited as a major advantage over incandescent alternatives. No significant negative user feedback was found in available sources.

3. Real-World Applications

The M22-DL-Y is used in industrial control panels, machine operator interfaces, and automation equipment across all industrial sectors. It has confirmed NSN procurement (NSN 5930-01-569-6748), indicating use in US military/government equipment. Distributors in Poland, Czech Republic, Spain, Mexico, Thailand, China, UK, US, Japan, and Australia stock the product, reflecting its use in global manufacturing and process automation. Common applications include conveyor controls, CNC machine panels, process plant HMI panels, and heavy machinery operator stations requiring IP67/IP69K washdown-rated controls.

6. Known Issues

Bezel material confusion is a minor catalog data-quality issue: some US distributors (RS Online US, Elliott Electric, Cooper Electric) describe the bezel as "Silver" or "SIL-BZL," while Eaton's own regional pages (CN, PL, MX) and Czech/Czech sources consistently say "titanium" colored plastic front ring — not chrome metal. This is the same component described differently: the bezel is a titanium-colored (silver-gray) plastic ring, not a metal chrome bezel (which would be the M22-DL-Y with optional M22-XBB metal collar). No functional issues or recall notices were found in any source. The Eaton Netherlands page (eaton.com/nl) displays a "serial number not recognised" note, which appears to be a regional CMS quirk and does not indicate a product validity issue.
