The LC1FK43M22 is marked obsolete by the manufacturer, with a lifecycle stage of eol_hot — meaning production has ended and no further orders are being accepted from the factory. For a BOM line that requires this exact order code, the only sourcing channel is the independent surplus and broker market.
What the Description Tells You
The description CONT 3P 2F2O 220V-50HZ decodes as a three-pole contactor with two normally-open and two normally-closed auxiliary contacts, powered by a 220 V 50 Hz coil. The 2F2O aux contact block is built in, not a separate add-on, so the overall depth on the DIN rail is fixed.
Deployment Context
Snap-on DIN-rail mounting suits it for standard panel integration. The 220 V 50 Hz coil means it is intended for European or 50 Hz mains supply regions — not a 60 Hz or 24 VDC control circuit.
