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.
Lifecycle & sourcing
Because it is an active, socketed controller with a common pinout, sourcing is straightforward — quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time; the 61F series has been in production for years, so supply is generally stable.
