Reed
Hall effect

The magnetic proximity switches CST/CSV detect the position of the cylinder’s magnetic piston. When the internal contact is actuated by a magnetic field, the sensors complete an electrical circuit and provide an output signal to actuate directly a solenoid valve or a PLC.
A yellow LED diode shows when the internal magnetic contact is closed. The Reed switch has a “mechanical switching” element and is suitable for voltages, AC and DC, up to 110V, and has a shorter operational life than Hall effect type. The Hall effect sensor has a longer operational life but as it is constructed from semi-conductor material is only suitable for DC voltages up to 30V.
The 2 types of proximity switches are both sealed in an epoxy resin and externally they are the same. These sensors are designed to fit into the grooves provided in the profile barrel of “compact” and “rodless” cylinders or on the surface of roundline and tie rod cylinders by using mounting bands or brackets.
