AIMS050 0.5″ AC Current Switch by Aim Dynamics

Product Description

Aim Dynamics’ AIMS050 Series turns an electronic switch ON at the threshold AC current, indicating the current passing through the core is equal or greater than the current threshold current of 0.015A to 5A, depending on the model ordered.

The AIMS050 is an AC current switch that utilizes a solid state contact, allowing for many years of use.  The current on the “secondary” can be up to 0.4A or up to 30V (AC or DC). The AIMS050 is ideal for detecting whether or not a device has been turned on, if it’s drawing too much current, or needs maintenance. The AIMS050 can be used as a relay to switch other devices on or off based on the current detected.


  • Sensing current from 0.015 to 250 Aac
  • Factory set threshold current rating
  • Solid state contact
  • 16” lead wires, 18 AWG
