Here is a quick look at how contactless potentiometers work, where they are used, and why they are gaining ground.

NEWTON, MA (February 16, 2010) – C&K Components, an international supplier of tact switches, toggle, rocker and pushbutton switches, and smart card interconnect devices, has developed two Hall-effect ...

Hall Sensor: A device that produces a voltage proportional to the magnetic field perpendicular to its surface, commonly used for current and position sensing.

The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly surrounded by a U-core magnetic field concentrator. “Its vertical Hall technology enables sensing parallel to ...

In operation, the bidirectional AC or unidirectional DC input current to be sensed flows through an internal conductor, generating a magnetic field measured by integrated on-chip Hall-effect sensors.

A current sensor IC from Allegro MicroSystems, LLC provides an economical and precise solution for AC current sensing in industrial, commercial, and communications systems.

The AS5601 is based on ams’ proven patented magnetic Hall position-sensing technology, which is already widely used in the automotive, industrial, medical and consumer markets.

3D Hall sensor for human-vehicle interfaces Diodes is aiming at contactless rotary motion and proximity detection with a 3D Hall-effect magnetic field sensor. Automotive applications are envisaged, ...
