The TeSys LX9FK916 is a specific contactor coil for the TeSys F contactor range, designed to operate on a 35...38 V DC control circuit with low consumption. It draws an inrush power of 550 VA at 20 °C and holds in at 31 VA, with a heat dissipation of 15...18.3 W during continuous operation.
The 35...38 V DC control voltage is the nominal operating band — the coil will pick up reliably between 0.85 and 1.1 Uc (roughly 30 to 42 V DC at 55 °C) and drops out between 0.3 and 0.5 Uc (about 10.5 to 19 V DC). That dropout margin is what keeps the contactor from chattering on a sagging 24 V bus. Opening time is 60 ms, closing 50 ms — fast enough for most motor start/stop sequences but not for high-speed jogging. The 3600 cycles/hour maximum at 70 °C matches typical conveyor or pump duty.
For a BOM replacement, the closest functional match would be a TeSys F coil with the same 35...38 V DC rating and low-consumption design, but pinout and mounting footprint should be verified against the existing contactor.
As a specific coil for the TeSys F range, it mounts directly onto the contactor's magnet system — no adapter plate needed. The coil technology is without built-in suppressor module, so if your circuit requires flyback suppression (e.g., PLC-driven outputs), you'll need an external RC snubber or diode across the coil terminals.
