The LX9FK913 is a specific contactor coil from the Schneider Electric TeSys F range, designed as a replacement or spare coil for TeSys F contactors. It operates on a control circuit voltage of 30...32 V AC or DC, with a 60 ms opening time and a 20 ms closing time — the opening speed matters for arc extinction on inductive loads, so if you're swapping a coil in a motor-starting circuit, that 60 ms is what governs contact separation.
Control circuit and coil technology
This coil is supplied without a built-in suppressor module, so you'll need to add an external RC snubber or varistor across the coil terminals if the control circuit drives inductive loads or if you're seeing noise on the PLC output. The control circuit type accepts AC 40...400 Hz or DC low consumption, meaning it works on standard 50/60 Hz line or DC supplies without derating. Inrush power hits 470 W at 20 °C, then settles to a hold-in consumption of 29 W — that inrush spike is brief but enough to sag a small 24 VDC supply if you're firing multiple coils simultaneously.
Operating limits and durability
Rated for an ambient temperature range of -5...55 °C, so it's fine inside a ventilated panel but not for direct outdoor exposure. The control voltage limits are tight: operational range is 0.85...1.1 Uc at 55 °C, and drop-out occurs between 0.3...0.5 Uc — meaning if your DC supply dips below about 9 V (on a 30 V nominal), the coil drops out and the contactor opens.
