The Omron 61F-GP-NH AC110 is a high/low level controller from the 61F series, designed for conductive liquid level detection in tanks, sumps, and process vessels. It operates on 110VAC supply and provides a SPDT relay output (2 Form C) rated at 3A @ 250VAC. Sensitivity is adjustable across 10kOhm to 40kOhm, matching the conductivity of the target liquid — lower resistance for high-conductivity fluids like salt water, higher for deionized or low-conductivity media.
Fit & Integration
The controller mounts to an 11-pin octal socket (sold separately) — standard for panel or enclosure integration. Termination is plug-in, making field swap or replacement straightforward without rewiring the base. The 50m maximum distance between controller and sensor electrode allows the electronics to sit remote from the tank, with the probe at the vessel. Operating temperature range of -10°C to 55°C covers most indoor industrial environments but not extended outdoor or freezer duty.
