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.
