The 61F-GP-N AC24 .: The Omron 61F-GP-N AC24. is a conductive-type level controller for high/low detection in water or chemical tanks. It switches a relay when the probe resistance crosses the adjustable 0 to 4 kOhm threshold — useful for fill-empty control, overflow alarms, or pump protection on a clean or slightly conductive liquid. Runs on 24 VAC supply and switches a SPDT relay rated 3 A at 250 VAC, enough to drive a small contactor or pilot lamp directly. The 1 km maximum distance between controller and sensor head means the sensing electrodes can sit at the far end of a large tank farm without a separate amplifier. Mounts into an 11-pin octal socket — standard panel layout, easy swap without rewiring. Operating range -10°C to 55°C covers most indoor plant-floor environments.

Frequently asked questions
Where can I buy the 61F-GP-N AC24. and get a price?
The 61F-GP-N AC24. is sourced to order against an RFQ through independent distribution. Submit a request for current pricing and availability — stock and lead time are confirmed at quote time.
What does the 0 to 4 kOhm sensitivity mean for my application?
The adjustable sensitivity sets the resistance threshold at which the relay switches. Set it low (near 0 ohms) for highly conductive liquids like salt water or caustic solutions; set it higher (up to 4 kOhm) for low-conductivity media like deionized water or light condensate. The probe resistance must fall below the set point to trigger the output.
What is the maximum distance between the controller and the sensor?
The 61F-GP-N AC24. supports up to 1 km between the controller and the sensing electrode. This lets the electronics sit in a central panel while the probes reach remote tank locations.
