Magnetic sensors

22 February 2012 Test & Measurement

Sensors in Infineon’s TLE492xC and TLE4957x families detect the motion and position of ferromagnetic and permanent magnet structures by measuring the differential flux density of a magnetic field. All sensors feature a self-calibration mode for optimum accuracy. After startup, only a few transitions are required before self-calibration has been completed and a high degree of operational accuracy has been achieved.

The sensors switch at either zero magnetic field crossing or at a viable hysteresis (adaptive or non-adaptive). Customers can also choose different watchdog settings. A broad temperature range, high ESD robustness and large EMC resistance make the products suitable for harsh automotive environments. A wide range of features and varying hysteresis concepts mean they are also suitable for Hall-based speed sensing in a wide variety of industrial applications. The sensors come in the proven PG-SSO package with three leads and two integrated capacitors.
