The LX9FH0602 is a specific replacement coil for the TeSys F contactor range, wound for 60 V AC control at 40 to 400 Hz. It is a low-consumption variant, meaning the hold-in power drops to 8 to 10 VA once the contactor is sealed, versus the 560 to 660 VA inrush at pickup. That inrush figure matters for transformer sizing in the control circuit — a 60 VA control transformer will not support this coil on its own; plan for the inrush peak. The 25 ms opening time and 45 ms closing time are the mechanical stroke durations at rated voltage. For a safety circuit timing study, the opening time is the relevant number — it defines how fast the main poles break under fault conditions. The closing time governs how quickly the contactor can re-energize a load after a momentary dip.
Control circuit and suppressor note
The coil is delivered without a built-in suppressor module. That means the end user must add an external RC snubber or varistor across the coil terminals if the control circuit contains solid-state outputs or PLC relay modules. Without suppression, the inductive kick from the coil at drop-out can exceed 1 kV — enough to damage a 24 V DC output card sharing the same panel. The datasheet's recommended suppressor part number is not listed here, but any standard 60 V AC RC suppressor rated for the coil's VA will work. Verify free-wheel diode polarity if using a DC-suppressed circuit on an AC coil — a diode will short the AC half-cycle.
Thermal and mechanical limits
Heat dissipation runs 8.4 to 10.4 W once the coil is sealed. In a densely packed panel with multiple TeSys F contactors side by side, that thermal load adds up — allow for natural convection or forced airflow if the ambient inside the enclosure exceeds 40 °C. The rated operating range is -5 to 55 °C ambient; the mechanical durability is 10 million cycles, and the maximum operating rate is 3600 cycles per hour at 55 °C. That rate is achievable only with the coil at full rated voltage and the contactor unloaded — derate for motor switching duty.
