The Omron 61F-GPN-V50-AC220 is a leak detection relay from the 61F series, designed to monitor conductive liquid levels or detect moisture paths. It operates on a 220VAC supply and features adjustable sensitivity from 0 to 50kOhm, allowing it to trigger on different liquid conductivities or leak thresholds. The relay output is SPDT (2 Form C) rated at 3A @ 250VAC, suitable for driving alarms, pumps, or control logic. The adjustable sensitivity means you can set the detection threshold to ignore false triggers from condensation or high-resistance films while still catching a real leak. This is critical in food-and-bev or chemical process lines where the fluid conductivity varies.
The relay mounts via an 11-pin octal socket (plug-in termination style), which simplifies panel wiring and allows quick replacement without disturbing the field wiring. The socketable form factor is standard for DIN-rail or panel-mount octal sockets — common in control cabinets for water treatment, sump monitoring, and leak detection systems. The SPDT contacts give you both normally-open and normally-closed switching for fail-safe wiring (e.g., alarm on open circuit).
