The LX9FL920 is a specific contactor coil from the TeSys F range, designed as a replacement or spare coil for TeSys F contactors. It operates on a control circuit voltage of 59...65 V DC and is classed as low consumption — meaning it draws less steady-state power than a standard AC or DC coil of the same frame size. Opening time is 60 ms, closing time is 20 ms. The coil has no built-in suppressor module, so you'll need to add an external RC snubber or flyback diode across the coil terminals if driving it from a PLC output or solid-state relay. Heat dissipation runs 22.8...27.8 W, which matters for panel thermal budgeting — especially if multiple contactors are ganged in a small enclosure. Inrush power at 20 °C is 733 W, but that's a transient; the hold-in power settles to 48 W at the same temperature.
Because it's a specific coil (not a universal replacement), confirm the mating contactor frame and the control voltage range before committing the line.
Installation and integration notes
The coil accepts AC control supply from 40 to 400 Hz as well as DC, but the rated voltage range is 59...65 V DC. Operational limits are 0.85...1.1 Uc at 55 °C; dropout occurs between 0.3...0.5 Uc at the same temperature. Ambient operating temperature is -5...55 °C. That's adequate for most motor-starting and resistive-load switching applications in a standard industrial panel.
