Safety switches are designed to pro-
tect both people and machinery from
numerous dangerous conditions that
exist not only in the industrial envi-
ronment, but also in the commercial
world. Some of the switches available
include: manual reset switches used
for elevators, cable pull switches used
for mining applications, convey-
ors or assembly lines, key interlock
switches used for safety doors and
barriers, hinge-mount switches used
for monitoring the position of doors
or gates. The most popular sizes and
shapes are offered. Their rugged metal
housings and economical plastic hous-
ings provide one to three 1/2" NPT
conduit entryways.
SMS safety magnetic sensors are used to monitor the position status of hinged, sliding,
or removable guards. Can be used in extremely harsh industrial environments where
dirty and damp conditions are common, as well as applications where washdown occurs.
The sensors are available in rectangular and cylindrical housings, with a variety of output
options. Specially coded magnets are also available, to guarantee the safety of the
system, by making the sensor impossible to trip with standard magnets. Conforms to
safety category 3 or 4, depending upon type.
