The LX1FK080 is a replacement coil for Schneider Electric TeSys LX1F series contactors, rated 80 V AC at 50/60 Hz. It is a bare coil — no built-in suppressor module — so you will need to add a separate RC snubber or varistor across the terminals if driving it from a PLC output or electronic controller. Opening time runs 100 to 170 ms; closing time is 40 to 75 ms. The coil draws 4.83 Ω inrush and 84.7 Ω holding at 20 °C, which matters for sizing the control transformer and verifying the drive circuit can deliver the peak inrush current without voltage sag.
The coil operates reliably between 0.85 and 1.1 times the rated control voltage (68 to 88 V AC) at 55 °C, and drops out between 0.3 and 0.5 Uc (24 to 40 V AC). That dropout range is wide enough that a marginal control supply or a long cable run with voltage drop should still release the contactor cleanly. For a coil that will see frequent cycling — say a pick-and-place or a rapid reversing application — that rate limit is the binding constraint, not the total cycle count. If the panel sits in an unconditioned space that sees higher ambient, the coil temperature rise from self-heating plus the environment may push the insulation beyond its rating — derate the operating rate or add forced ventilation.
Integration notes
This coil snaps onto the LX1F contactor magnet assembly. The control circuit is AC only — 50/60 Hz — so do not apply DC to it; the impedance and dropout characteristics are designed for sinusoidal AC, and DC operation will overheat the coil or fail to drop out.
