The LX9FH0362 is a specific contactor coil from the TeSys F range, designed for 36 V AC control circuits at 40-400 Hz. It is a low-consumption coil without a built-in suppressor module, meaning you need to add external suppression (RC snubber or varistor) across the coil terminals if driving it from a PLC output or electronic controller — the lack of internal suppression means the coil's inductive kickback is unmanaged until you add it.
The coil pulls 560-660 VA inrush at 68 °F (20 °C) across 40-400 Hz, then settles to 8-10 VA holding. That inrush current matters for transformer sizing in the control panel — a 36 V control transformer must handle the momentary surge without dropping below 0.85 Uc (30.6 V) or the coil may chatter on pickup. The holding power is modest, so continuous heat dissipation runs 8.4-10.4 W; in a densely packed panel, that adds up but is manageable with basic ventilation. Opening time is 25 ms, closing time 45 ms. That's typical for a contactor coil of this size — fast enough for motor starting but not for high-speed switching. The control circuit is AC low-consumption type, with operational limits of 0.85-1.1 Uc (30.6-39.6 V) at 131 °F (55 °C) and dropout at 0.35-0.55 Uc (12.6-19.8 V). The wide dropout margin means the coil releases reliably even on a sagging control supply — useful if your panel shares a transformer with other loads. Coil resistance measures 1.88 ohms inrush and 41.8 ohms holding at 68 °F (20 °C). The inrush resistance is essentially the DC resistance of the copper winding before the armature moves; once the contactor seals, the holding resistance rises as the magnetic circuit changes. This is normal for AC-operated contactor coils.
