Warning— Each electrical rating is an individual maximum and cannot be exceeded!
1 Configuration with actuator away from the switch
2 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.
3 Can withstand inrush surge up to 4 amps. Voltage drop is 1.5V. Minimum Switch Current 30mA.
4 Do not exceed 10 switches in series.

Mounting Configurations
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 safety interlock applications.

4. For best protection against operator defeat, mount with
non-removable screws, bolts or nuts (see Accessories).
5. When mounting a metal switch to an ungrounded machine, connect the ground lead
to one of the switch mounting screws.
