FSU Flow Detection Switches

Cynergy3 / Sensata FSU Flow Detection Switches offer a 25V maximum switching power rating, 0.6A switching current, and 240VAC switching voltage. These switches feature a design that is based around a moving magnet and a fixed reed switch with a low flow restriction. FSU switches have industry-standard process connection sizes (push-fit or NPT thread) that provide a quick and reliable method of installation. Cynergy3 / Sensata FSU Flow Detection Switches are ideal for industrial washers and garment cleaners.
