Speed Sensors
-
DHE (Differential Hall Effect) sensors give an output when subjected to a changing magnetic field. The field is set up by a magnet inside the sensor body and changes when ferromagnetic teeth are passed beneath the sensor (no magnets are required in the target). To improve noise resistance, the sensor has two Hall effect elements and only responds to changes in magnetic field strength corresponding to tooth passing frequencies above 15Hz. As each tooth passes the sensor, the digital state of the output changes.

Composite inductors are constructed by inserting a pre-wound coil over pre-press magnetic core and then pressing or molding a magnetic material around this assembly. The composite inductors are very similar to molded but typically offer lower DCR and lower overall losses. Our composite core inductors provide a fully shielded, high energy density, soft saturation solution for applications up to 120Apk. The construction enables the highest energy density of any available SMT inductors and also minimizes acoustic noise. We offer both commercial grade (-40C to 125C) and automotive grade (-55C to 155) in a wide range of platforms from 4x4x2mm to 17x16x13mm.
