Contact-Free Limit Switch Type 024.50

Product catalog summary

Overview
Limit switches are essential components used to control, monitor, and indicate the position of valves or activate other system components. Various types of on/off limit switches exist, including mechanical switches, proximity sensors, and potentiometers. SED has developed a contact-free limit switch utilizing magnetic field measurement technology, offering enhanced reliability and sealing methods.

Features

Designed for single and double-acting valve control functions.
Compatible with linear and rotary actuators.
Supports linear stroke measurement from 3 to 45 mm.
Indicates two or three positions with backlash-free stroke transmission.
Short circuit proof with M12, 5 pin A-coded connection.
ATEX II 3G Ex nC IIB T6 certified.

Advantages

Contact-free magnetic measuring design.
360° visible colored LED light feedback for valve position.

Catalog excerpts

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 mechanical 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.
