• When mounting on ferrous material (steel), a 1/4" nonferrous (plastic or
aluminum) spacer may be used under the actuator and switch to restore most of
the lost gap.
• When mounting on a hinged gate or door, mount the switch and actuator at least
6" away from the hinges to achieve the maximum movement.
• The switch and actuator must move in one of the approved directions.
See figure 2.
• The actuator can be mounted at a 90
°
rotation to the switch.
• Do not mount for parallel actuation. An on-off-on signal may result when the
actuator passes by the switch.
2. Mount the switch on the stationary frame of the machine and connect the electrical
wiring. When mounting the switch on an ungrounded machine, connect the ground
lead to one of the mounting screws.
3. Mount the actuator on the movable guard, door, or gate.
