It draws an inrush resistance of 1.78 Ω and a holding resistance of 296.7 Ω at 68 °F (20 °C). The coil is supplied without a built-in suppressor module, so you'll need to add external flyback suppression (diode or RC snubber) across the coil terminals to protect the control circuit from inductive kickback. The 35 V DC control voltage (Uc) operates between 0.85 and 1.1 Uc at 131 °F (55 °C), so the coil pulls in reliably from about 29.8 V to 38.5 V DC. Drop-out occurs between 0.15 and 0.2 Uc (5.25 to 7 V DC), which means the contactor drops out cleanly on a sagging supply — no partial engagement. Closing time is 30 to 40 ms, opening 30 to 50 ms; that's standard for a power contactor coil and compatible with most PLC-driven outputs as long as the cycle rate stays under 10 operations per minute. The coil mounts directly onto the TeSys F contactor magnet assembly. No built-in suppressor means you must add an external diode (reverse-biased across the coil) or an RC snubber — without it, the inductive flyback can weld relay contacts or damage the PLC output driving it. The DC low-consumption design keeps holding power low, so the coil runs cooler than a standard DC coil of the same rating.","metaTitle":"TeSys LX4FF035 contactor coil, 35 V DC, obsolete","metaDescription":"Obsolete TeSys LX4FF035 contactor coil, 35 V DC, DC low consumption, no built-in suppressor.

You would need to cross-reference a current TeSys F-series coil with the same 35 V DC rating and mounting pattern.
