It is the replacement coil for TeSys F contactors that use a DC-operated latch-and-unlatch scheme. Operating time is 50...100 ms unlatching and 40...80 ms latching. Average coil resistance is 28.25 Ω latching and 313.6 Ω unlatching at 20 °C. That resistance split is typical of a dual-winding or economizer circuit: the latching winding pulls in the armature, then the higher-resistance unlatching winding holds it with lower power draw. This part is marked obsolete by the manufacturer. We can quote this against an RFQ from our multi-source channel. Because it is obsolete, lead time and availability vary; a firm order with a quantity and target date is the fastest way to get a committed position. ## Mechanical endurance and operating rate That is a standard endurance figure for a contactor coil in a TeSys F frame — suitable for frequent starting applications like conveyors or pumps, but not for continuous high-speed pick-and-drop.","metaTitle":"TeSys LX0FK057 contactor coil, 127 V DC low consumption","metaDescription":"TeSys F LX0FK057 contactor coil, 127 V DC low consumption.
