It operates on a 100 V AC control circuit at 40...400 Hz and is built for low consumption — meaning less heat dumped into the panel over the duty cycle. The coil draws 560...660 VA inrush at 68 °F (20 °C) and settles to 8...10 VA holding at the same temperature. That inrush-to-hold ratio is typical for AC-operated contactor coils; the holding power is low enough that a standard control transformer can supply multiple coils without sagging the rail. Coil resistance measures 15.11 Ω inrush and 330 Ω holding at 68 °F (20 °C). The wide difference between inrush and holding resistance is what creates the magnetic pull-in force, then drops to a lower holding current to keep the contactor sealed without overheating. ## Timing and Thermal Behaviour Opening time is 25 ms, closing time is 45 ms. That 20 ms difference is normal for AC coils — the closing stroke has to overcome spring force and seat the armature, while opening is just spring return after the coil drops out. Heat dissipation runs 8.4...10.4 W depending on the operating point. That's the power the coil dissipates as heat in the enclosure; if you're packing multiple contactors in a sealed panel, that thermal load adds up and may need derating or forced ventilation above the 131 °F (55 °C) upper ambient limit. That rate is fast enough for most repetitive machine cycles — a conveyor indexing every second, for example — but sustained high-speed switching will heat the coil and reduce the thermal headroom. ## Control Voltage and Drop-Out Margins The coil is rated for 100 V AC control voltage, with operational limits of 0.85...1.1 Uc at 131 °F (55 °C) — so it holds in reliably down to 85 V and up to 110 V. Drop-out occurs between 0.35...0.55 Uc, meaning the contactor releases somewhere between 35 V and 55 V. That wide drop-out band is intentional: it prevents nuisance drop-out from a brief voltage sag, but if your control transformer sags below 35 V, the contactor drops and you lose the load. There is no built-in suppressor module on this coil. That means the inductive kickback from the coil when it de-energizes is unfiltered — you need an external RC snubber or a free-wheeling diode across the coil terminals if your PLC output or relay driving it can't handle the back-EMF. Check the coil suppression requirements against your control circuit before wiring. Because it is a specific contactor coil — not a universal replacement — verify that the mechanical interface and stroke match the TeSys F contactor frame you are fitting it to. The LX9FH prefix is the coil family for the F frame; the 1002 suffix indicates the 100 V AC variant. If your contactor is a TeSys F model, this is the correct coil. If you are working with a different TeSys frame (D, K, or another), the mechanical fit and electrical ratings differ.","metaTitle":"TeSys LX9FH1002 Contactor Coil, 100 V AC, Low Consumption","metaDescription":"TeSys F specific contactor coil, 100 V AC 40-400 Hz low consumption.
