It's the part you swap when the coil on a FK contactor opens or the control voltage drops out; no built-in suppressor module, so plan for an external flyback diode or RC snubber across the coil terminals if your PLC output or relay can't handle the inductive kick. Operating time runs 45 to 60 ms on opening and 50 to 60 ms on closing — that's standard for a DC coil this size, but if your safety circuit demands faster break, this won't meet a sub-30 ms window. The holding resistance sits at 1917 ohms at 20 °C, with an inrush resistance of 7.47 ohms at the same temperature; that inrush-to-hold ratio means the coil draws a healthy surge on pickup, so size your 90 V DC supply to handle the momentary load without dropping below the 0.85 Uc operational limit. Drop-out threshold is 0.2 to 0.35 Uc at 55 °C — roughly 18 to 31.5 V DC — so the contactor stays in during a brownout down to about a third of nominal.","metaTitle":"TeSys LX4FK090 contactor coil, 90 V DC, active","metaDescription":"TeSys LX4FK090 contactor coil for FK series, 90 V DC control, active lifecycle.
