The Omron 61F-GPN-V50 AC240 is a socket-mounted leak detection relay from the 61F series, designed to sense conductive liquid presence or absence through an adjustable probe circuit. It operates on a 240VAC supply and provides a SPDT relay output rated for 3A at 250VAC — enough to drive a small pump, alarm horn, or PLC input directly. Sensitivity is adjustable from 0 to 50 kΩ via an onboard potentiometer, which lets you tune the detection threshold for different liquid conductivities — from deionized water (high resistance) to conductive process fluids (low resistance). This is the main tuning parameter on installation; set it too sensitive and you get false trips on condensation, too insensitive and it misses a leak.

Product details
Frequently asked questions
What is the sensitivity range of the 61F-GPN-V50 AC240?
Sensitivity is adjustable from 0 to 50 kΩ, allowing the relay to detect leaks in fluids with varying conductivity — from nearly deionized water to conductive process liquids.
What is the closest pin-compatible alternative to the 61F-GPN-V50 AC240?
The 61F-GPN-V50 AC240 is a specific variant with a 0–50 kΩ adjustable sensitivity range and 240VAC supply. Other 61F-GP variants share the same 11-pin octal socket and SPDT relay output but differ in fixed sensitivity values (e.g., 0–10 kΩ or 0–100 kΩ) or supply voltage (e.g., 24VAC/VDC). The pinout is consistent across the 61F-GP family, so swapping between them requires only a sensitivity re-check at commissioning.
