Contact-free Limit Switch 024.50

Limit switches are used to control, monitor and view the position of the valve or to activate other system components. There are different versions of on/off limit switches in the market. The most common are based on the principle of echanical switches, proximity sensors or potentiometers. SED has designed and engineered a contact-free limit switch with magnet field measurement technology. Apart from lifetime and among other features the advanced design allows also a more reliable sealing method.
