Description
Position limit switches are
designed to control the movement
of overhead travelling cranes,
hoists and machine tools. They
operate as auxiliary controllers
of electrical motors through
power interfaces, such as contactors
or PLCs.
Both the enclosure and the
head of the limit switches are
made of thermoplastic material
(nylon reinforced with fibre
glass). Materials and components
ensure high resistance and endurance
and protect the equipment against
water and dust.
The X-FCS series has “T”
or “Cross” rods
which may move to 3 or 4 maintained
positions, while the X-FRZ series
features a single rod or a rod
with roller with spring return
movements.
The limit switches are equipped
with 1NO+1NC snap action switches
or, upon request, with 1NC slow
action switches. All switches
are of the positive opening
type, thus suitable for safety
functions.
