Three-Wire Hall-Effect Switches

Perfect for sensing absolute position or proximity in harsh automotive environments, our three-wire switches are ideal for applications like shift selectors, door ajar, user interfaces and vane-interrupt systems. Our Hall switches offer 4× chopper stabilization for superior temperature stability and resistance to physical stress, and all new devices are designed to ISO 26262 for functional safety.

We offer both planar and vertical Hall options and provide a broad range of device sensitivities that cover just about any application requirement.
