Actuator Only Included with all switches unless otherwise noted.
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
Rated at 3.0A for 6,000 cycles only. Other ratings are at 100,000 cycles.
4
Can withstand inrush surge up to 4 amps. Voltage Drop 1.5V, minimum switch current 30mA.
5
Maximum 10 switches in series.

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.
