The Omron 61F-G1N is a compact floatless level switch (G1N type) in Omron's 61F-G[]N family, designed to sense liquid levels without a moving float. It is configured as a base (61F-G1N) plus two 61F-11 units and is intended for automatic water-supply applications, including pump dry-run prevention or a low-water alarm when used with AC mains power (AC100/200 V). The mounting options include DIN rail or screw mounting, and the unit has a compact footprint roughly 75 mm wide. This model sits within the broader 61F-G[]N lineup, with variants such as GN, GNL, GNH, GND, and GNR available.
