It operates by sensing conductivity through electrodes in the liquid — when the resistance between probes drops below the set threshold (0 to 0.7 kOhm adjustable), the internal SPDT relay switches. That relay contact is rated 3A at 200VAC, enough to drive a small pump contactor or alarm. The headline spec here is the 4 km maximum distance between the controller and the sensing electrodes — that's not a typo. It means the controller can sit in a central panel while the probes are at the far end of a long tank farm or remote sump, without signal degradation. For comparison, many level relays top out at 100 m or 1 km. ## Power and mounting Powered by 110 or 220 VAC — selectable, not auto-ranging — so verify your line voltage before wiring. The screw terminals accept standard panel wire, and the housing snaps onto a DIN rail.","metaTitle":"Omron 61F-GNL AC110/220 4KM Level Controller, 4 km, SPDT, DI","metaDescription":"Omron 61F-GNL AC110/220 4KM High/Low level controller, 110/220VAC supply, 4 km max sensor distance, SPDT relay output, DIN rail mount.

This is the resistance threshold between the electrode probes — when liquid conductivity makes the resistance fall below the set point, the relay trips. Lower settings (closer to 0) work for more conductive liquids like salt water; higher settings handle less conductive fluids like deionized water."},{"question":"Where can I buy the 61F-GNL AC110/220 4KM and get a price?","answer":"This part is sourced to order against an RFQ through independent distribution.
