The Telemecanique LX9FG090 is a specific contactor coil from the TeSys F range, designed to mount on TeSys F contactors. It operates on a 90 V AC control circuit at 40 to 400 Hz, drawing 950 to 1180 VA inrush and 8.9 to 10.9 VA holding at 68 °F (20 °C). The coil has no built-in suppressor module, so external suppression (RC snubber or varistor) must be added across the coil terminals when driven by a PLC output or electronic timer to prevent voltage spikes from damaging the driver. Opening time is 130 ms, closing time 35 ms, with a maximum operating rate of 2400 cycles per hour at 131 °F (55 °C).
Key electrical parameters for fit
Control voltage limits: operational range is 0.85 to 1.1 Uc (76.5 to 99 V AC) at 131 °F (55 °C); dropout occurs between 0.35 and 0.55 Uc (31.5 to 49.5 V AC). This means the coil will hold in reliably down to about 77 V AC but will drop out if voltage sags below roughly 32 V AC. Average coil resistance: 6.92 Ω inrush, 220 Ω holding at 68 °F (20 °C). Heat dissipation runs 8 to 9.8 W, which must be considered in enclosure thermal calculations, especially in a densely packed panel. Ambient operating temperature range is 23 to 131 °F (-5 to 55 °C).
Deployment context
The coil is a replacement or spare part for existing TeSys F contactor assemblies — not a standalone component.
