The LX9FF065 is a specific replacement coil for the TeSys F contactor range, wound for 65 V AC 40-400 Hz control circuits. It's a low-consumption design — inrush pulls 690-855 VA at 20 °C, then drops to 6.6-8.1 VA holding, with coil resistance settling at 152.2 Ω once sealed. Opening time is 130 ms, closing 35 ms, which is standard for this frame size. This is the coil only — no built-in suppressor module, so you'll need to add a varistor or RC snubber across the terminals if driving it from a PLC output or solid-state relay. The heat dissipation runs 5.9-7.2 W, so check for adequate ventilation inside the enclosure if multiple contactors are ganged.
This part is marked obsolete by Schneider. That's a solid service life for a contactor coil — the obsolescence isn't driven by wear-out, just Schneider's platform migration.
The 65 V AC control voltage is the first thing to verify — this is not a 24 V or 110 V coil. It operates between 0.85 and 1.1 Uc (55.25-71.5 V AC) and drops out between 0.35 and 0.55 Uc (22.75-35.75 V AC). If your control transformer is putting out 48 V or 120 V, this coil won't pull in reliably or will burn up. The inrush VA figure (690-855 VA) matters for transformer sizing — a 100 VA control transformer won't handle the inrush of this coil plus others pulling in simultaneously.
