Warning— Each electrical rating is an individual maximum and cannot be exceeded!
Note: This switch cannot be used for AC applications. In DC applications it is polarity sensitive white to positive, black to negative.

Configuration with actuator away from the switch

Proximity of ferrous materials usually reduces sense range — typically by 50%. The shape and type of material cause a wide diversity of effects.
Testing is required to determine actual sense range for specific applications.

Mounting Configurations
Three configurations are appropriate for interlock applications. The parallel
actuation can result in on/off/on signal if the actuator passes by the switch rather
than coming to rest in proximity to it. This is NOT a recommended configuration for
interlock applications.
• 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.
