The Omron 61F-IN AC110/220 is a High/Low Level controller from the 61F series, designed to detect and control liquid levels in tanks, reservoirs, or sumps using conductive probes. It operates on a 110/220VAC supply and provides two SPDT relay outputs (2 Form C) rated at 3A @ 200VAC, giving you independent alarm or pump control for high and low setpoints. Sensitivity is adjustable from 0 to 4kOhm, which means you can tune it for different liquid conductivities — from clean water to more conductive process fluids. The control-to-sensor distance can be up to 1km, so the controller can sit in a central panel while the probes are out at the tank.

Product details
Frequently asked questions
What is the supply voltage for the 61F-IN AC110/220?
The supply voltage is 110/220VAC, so it works on either 110V or 220V AC mains without needing a separate transformer.
What type of level control does the 61F-IN AC110/220 provide?
It is a High/Low Level controller, meaning it can monitor both the high and low liquid levels and switch relays accordingly — typically for fill or drain pump control.
What is the maximum distance between the controller and the sensor probes?
The maximum control-to-sensor distance is 1km, which allows the controller to be located in a central panel while the probes are at a remote tank.
Where can I buy the 61F-IN AC110/220 and how is it quoted?
We source and quote this part to order against an RFQ. Current pricing and availability are confirmed at quote time through our independent distribution network.
