The Omron 61F-GP-N AC220 is a conductive-type level controller from the 61F series, designed for high/low level detection in tanks, sumps, and reservoirs. It operates on a 220VAC supply and uses a relay output (SPDT, 2 Form C) rated at 3A @ 250VAC to switch pumps, valves, or alarms. Sensitivity is adjustable from 0 to 4kOhm, which lets you tune the detection threshold for different liquid conductivities — from clean water to more conductive process fluids. The control-to-sensor distance can run up to 1 km, making this suitable for remote tank farms or deep wells where the controller sits in a panel far from the probes. It mounts on an 11-pin octal socket (sold separately), so replacement is a plug-in swap — no rewiring at the terminal block. The operating range is -10°C to 55°C, which covers most indoor industrial environments.
Lifecycle & Sourcing
The 61F-GP-N AC220 is listed as Active in production, so it remains a standard catalog item through Omron's distribution channel.
