Warning— Each electrical rating is an individual maximum and cannot be exceeded!
1
The part numbers 301 and 303 are the same in all respects except the cable exits 301 left and 303 right.
2
Configuration with actuator away from the switch
3
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.
4
Can withstand inrush surge up to 4 amps. Voltage drop is 1.5V. Minimum Switch Current 30mA.
5
Do not exceed 10 switches in series.

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 safety
interlock applications.
