ASCO (Emerson) 400904-541
ASCO CM22 spade-plug solenoid coil, 2,5/3 W class
ASCO 400904-541 is the 12 V DC entry in ASCO's CM22 2,5/3 W replacement-coil table for its 108, 109, 189 banjo and 551 series valves; 12 V DC sits outside ASCO's published standard voltages for that range, which are 24 V and 48 V DC. This Airtac CDA092F matches it on voltage - 12 V DC, 10,8-13,2 V - and draws 2,5 W, but it is temperature classification B rather than ASCO's class F, and its PHI 9,0 mm coil bore and 4V210-005-P3 connector are made for Airtac 3V1, 3V200/300, 4V200/300/400, 4M200/300 and ESV200/300/400/600 valves. It is an electrical counterpart, not a mechanical drop-in; check the coil bore and terminal arrangement against your valve before ordering.
