Bumper Accessory
External bumpers are available on these units for safety reasons or as emergency stops. These bumpers
are designed as safety stops only and should not be used as end of stroke stops. Continuously using them
as end of stroke stops may damage the drive train. See the diagram below for an exploded view of the
bumper option.
Hall Effect & Reed Switches
Hall Effect and Reed switches are available for sensing the position of the carriage. This is accomplished by
detecting the magnet attached to the carriage. Magnets come as standard on all units. The switches may
be attached to either of the side T-slots on the actuator body and are easily adjusted to any position along
the length. See the figure below for the mounting bracket hardware needed for the switches.
