OMRON 61F-GP Floatless Level Switch

The OMRON 61F-GP is a floatless level switch engineered for reliable detection and control of conductive liquid levels in industrial environments. This compact, plug-in design eliminates float mechanisms, reducing maintenance burden while delivering fast response times and independent dual-contact outputs for pump control, alarm indication, and integrated level-sensing functions.
