Crafted from corrosion-resistant brass with a 3/4" BSP male thread, it supports 0-220V AC/DC operation and up to 1.75 MPa pressure. Ideal for water heaters, pumps, and industrial equipment, it ensures automatic power cutoff when flow stops, safeguarding your devices with reliable, compact performance. ## Description Main application:Magnetic Water Flow Switch adopts a Magnetic Reed Switch and a movable magnet which is fixed inside the water pipe. When water runs through the pipe part, the magnet will detect the water flow, and the magnet is shoved to one side by the flow. This then attracts the conductive strip which gets pulled down and makes contact, which completes the circuit and activates whatever electrical device you have attached to itSpecifications:Thread type: 3/4" BSP Male ThreadIt is fit in NPT Thread if you connect them with teflonOperation voltage: 0-220V(AC or DC)Flow range: 1-30L/minWorking temperature: 1-120℃Mini start water pressure: 0.02MpaMax working pressure: 1.75 MPaMax loading power: 50WWorking current: 0-2AResponse time: 0.2SMaterial: BrassMale Thread External Diameter: 25.85mm(1.0 inch)Tube Length: 60mm(2.36 inch)Cable Length: 29cm(11.41 inch)Size: 60mm*30mm*30mm(L*W*H)Please Note:Don't forget to mark which way the old flow switch arrow is pointing so you can install exactly the same.Package Include:Brass Flow Switch x 1 ## Features - 🌟🌊【Safe and Reliable】This flow sensor switch is made of brass, all materials are in line with ROHS testing standards.
