What is the AMISCO 3009MA220W2 coil?

An ATEX-certified encapsulated solenoid coil from AMISCO in Italy — order number 3009MA220W2 — built for hazardous-area valve service, and the marking block on the moulding is the whole story: II 2G Ex mb IIC T5 Gb / II 2D Ex tb IIIC T95°C Db · TÜV IT 13 ATEX 030 X · IECEx IMQ 22.0004 X · CCC Ex mb IIC T5 Gb / Ex tb IIIC T95°C Db — gas and dust certification for both ATEX and IECEx schemes plus CCC, on an encapsulated ("mb") coil. Electrically it is U = 220 VAC, I = 14.6 mA, ambient −20 to +50 °C, IP66, from AMISCO i-20057 (MI) ITALY with CE. The coil is a black moulded body with the metal threaded collar for the valve armature tube, an Ex-marked top face, and — the part fitters appreciate — a 3-metre screened cable moulded in (brown / blue / green-yellow earth over a braided shield), so the hazardous-area wiring is a gland and a terminal, not a connector you must certify. Four sets, new in the AMISCO factory bags (Avvolgimenti elettrici — electrical windings), recorded 23 December 2025 at about 1 kg as recorded, one-year warranty. Seven photos plus the warehouse video below.

Reading the "explosion-proof" honestly

The marking says something more specific than the headline: Ex mb is encapsulation — the coil is potted so that no ignitable interior exists, which is a different (and in many ways friendlier) protection concept than a flameproof enclosure. For the buyer this means three practical things. You may fit this coil anywhere the Zone 1 / Zone 21 (2G/2D) classification applies without a heavy Ex-d housing — the moulding is the certification. The 3 m screened cable is part of that certified arrangement: route it through a certified gland into your junction box, land the green-yellow earth on the shield and the earth point both, and keep the screen continuous — an uncertified plug-in connector would undo the Ex rating. And the numbers matter when you replace like-for-like: 220 VAC at 14.6 mA is a low-draw AC coil, and the sister versions in the 3009 family change voltage and letter (the MD-type DC24V coil is the common alternative), so match the full order number to your valve's duty, not just the connector shape. All four sets here are factory-bagged Italian production with the marking crisp on every moulding.

Bag label close-up — The AMISCO bag label: red brand block, Avvolgimenti elettrici, and the coil set with its 3 m cable below.

Cable end detail — The cable end: brown, blue and green-yellow conductors over the copper braid shield — the screened lead the Ex approval expects you to land correctly.
