Coil for TeSys F contactors — what fits and what doesn't
The LX9FJ929 is a specific replacement coil for the TeSys F contactor range. It's the part you swap when the coil burns open or the control voltage changes on an existing contactor — not a standalone contactor itself. Rated for 157-175 V DC or 180 V AC 40-400 Hz, so it handles both a DC control bus and an AC control transformer on the same coil, but not simultaneously. Opening time is 60 ms, closing time 20 ms. That matters when you're sequencing contactors in a star-delta start or reversing drum: the slower open gives the arc time to clear, the fast close keeps arcing duration short on make. No built-in suppressor module. That means you need an external flyback diode for DC control or an RC snubber for AC if the PLC output or relay driving it doesn't have one onboard. The coil draws 500 VA inrush at 20°C, dropping to 23 VA hold-in — size the control transformer for the inrush, not the sealed VA.
Electrical and thermal limits for panel integration
Heat dissipation runs 11.4 to 13.9 W when sealed. That's not trivial in a crowded enclosure — account for it in the thermal budget, especially if the contactor is mounted next to other heat sources like power supplies or drives. That suits high-cycle applications like conveyor sortation or packaging lines where the contactor cycles every second. Drop-out voltage is 0.3 to 0.5 Uc at 55°C — the coil drops out cleanly between 47 and 87 V DC, so it won't chatter on a sagging bus.
What the category code tells you
The category 22341 maps to contactor accessories — specifically coils for the TeSys D, K, and F ranges. This LX9FJ929 is the F-range variant, physically larger than the D/K coils and with higher inrush. Don't cross-fit a D-range coil into an F contactor; the mounting flange and magnetic circuit are different.
