The part numbers 381 and 383 are the same in all respects except the conduit connection, 381 is left and 383 is 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.

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.
