MATelec FSW-12571 Stainless Steel Vertical Long Stem Magnetic Float Switch

Taller tanks and vessels where the switching level is positioned further below the mounting flange require a longer stem to position the float at the correct detection height, and the FSW-12571 provides the same magnetic reed switch technology as the short stem variant within a long stem 304 stainless steel assembly. The vertical orientation allows the float to travel along the extended stem as liquid level changes, and the unit includes approximately 300 mm of cable for connection to the pump controller or instrumentation circuit.

Electrical specifications match the FSW-12570 platform, with a maximum contact rating of 50 W, maximum switching voltage of 24 V DC, and maximum switching current of 1.5 A. The maximum breakdown voltage is 240 V DC, and the maximum carry current is 3.0 A. Contact resistance is 100 m?, and the magnetic reed mechanism provides consistent switching performance across the operating range. The float and stem body are manufactured from 304 stainless steel for compatibility with corrosive service conditions.

The float dimensions are 28 mm wide by 26 mm high, with a specific gravity of 0.70 that enables the float to respond to liquid level changes within the specified density range. The M10 x 1.6 threaded connection accepts standard mounting fittings, and the cable outlet is sealed with epoxy to prevent moisture ingress. A gasket seal at the stem entry point provides additional protection against liquid penetration into the switch housing cavity.
