It is the FK-type coil that mates with the corresponding TeSys contactor frame — the part you order when the original coil on a 65 V DC line has failed or you are stocking a spare for a critical motor starter. The 65 V DC control voltage is the key fit parameter: if your panel runs a 65 V DC control bus, this coil drops straight in. Operating time is 40 to 50 ms on opening and 60 to 70 ms on closing, which is typical for a DC-operated contactor coil in this frame size. The coil ships without a built-in suppressor module, so you will need to add an external flyback diode or RC snubber across the coil terminals if your circuit does not already include one — standard practice for DC coils to protect the control contacts from inductive kickback. ## Control voltage limits and temperature range The coil holds in reliably between 0.85 and 1.1 times Uc at 131 °F (55 °C), so for a 65 V DC nominal supply it will pick and seal from about 55 V up to 71.5 V. Drop-out occurs between 0.2 and 0.35 Uc — roughly 13 to 23 V DC — meaning a significant brownout is needed before the contactor drops out. Ambient operating temperature spans -5 to 55 °C (23 to 131 °F), which covers most indoor panel environments but not extended high-heat zones near furnaces or ovens without derating. ## Integration note The LX4FL coil mounts directly onto the TeSys contactor magnet assembly — no adapter plate, no wiring harness modification needed if the existing contactor frame is the same series. Verify the contactor body part number against the TeSys compatibility table before ordering; the FK coil designation narrows it to the specific frame size. Single unit per package, so order the quantity you need for the number of contactors you are servicing.","metaTitle":"TeSys LX4FL065 Contactor Coil, 65 V DC, Active","metaDescription":"TeSys LX4FL065 contactor coil, 65 V DC control voltage, 40-50 ms opening / 60-70 ms closing.
