KMI17-4 - Rotational speed sensor

General Description

Based on the Anisotropic MagnetoResistive (AMR) effect, the KMI17/4 detects the rotational speed of passive target wheels (i.e.

having ferromagnetic teeth).

This design delivers secure speed information over a wide range of speed, air gap and temperature.

627( KMI17/4 Rotational speed sensor Rev. 1 — 1 September 2014 Product data sheet 1. Product profile CAUTION 1.1 General description Based on the Anisotropic MagnetoResistive (AMR) effect, the KMI17/4 detects the rotational speed of passive target wheels (i.e. having ferromagnetic teeth). This design delivers secure speed information over a wide range of speed, air gap and temperature. It delivers the speed information via a current protocol at the supply pins. Do not press two or more products together against their magnetic forces. 1.
