Eaton M22-T-D – Frequently Asked Questions

1) Will the Eaton M22-T-D diaphragm fit my 22.5 mm pushbutton cutout?
Yes. The M22-T-D protective diaphragm is built for the 22.5 mm M22 device size, so it drops onto a standard 22.5 mm panel cutout used by M22 pilot devices. Its overall footprint is 1.3 in wide by 1.3 in long with a .67 in height, so allow that clearance around neighboring devices on a crowded panel face.
2) Can I use this Eaton M22 diaphragm over an extended or mushroom head pushbutton?
No. The M22-T-D is specified for flush pushbuttons and indicating lights only. Extended, mushroom, and emergency-stop heads sit proud of the bezel and are not what this diaphragm is dimensioned for, so for those operators you need a boot or head style intended for that profile.
3) Is this M22 diaphragm rated for washdown areas in a food plant?
It is. The M22-T-D carries IP67, IP69K, NEMA 4X and NEMA 21 environmental ratings. IP69K is the high pressure, high temperature washdown rating that food and beverage equipment gets specified to, and NEMA 4X adds corrosion resistance for caustic sanitation chemicals.
4) Does the Eaton M22-T-D have approvals I can put on a submittal for an industrial control panel?
Yes, it is CSA Certified and CE Marked, which covers the usual paperwork for specifying it into commercial and industrial control systems on both sides of the border.
5) What part number do I order for the Eaton M22 protective diaphragm?
The catalog number is Eaton M22-T-D. It is the protective pushbutton and indicating light diaphragm in the M22 modular pilot device series, ordered as a separate accessory from the operator head and contact blocks.
6) Will adding this diaphragm to an existing M22 station keep the panel sealed outdoors?
That is what it is for. The diaphragm seals at the device face against dust, moisture and contaminants on existing M22 flush pushbutton and indicating light stations, and its IP67 rating covers temporary immersion, which is the case a property manager or plant electrician cares about on an outdoor or wet-location enclosure. It only protects the operator it is fitted to, so every device in the enclosure needs its own.
7) Does the M22-T-D come in different colors or sizes?
No, it is a single item. The M22-T-D is offered in one configuration for the 22.5 mm M22 device size, so there is no color, size, or option to select when ordering.
