Differential Hall Switch and Gear-Tooth Sensor with Line Driver

Features

• Dual Hall sensors set 2.0 mm apart

• Magnetic field frequency range from DC to 40 kHz

• Supply voltage range 4.5 to 36 V

• Complementary push-pull line driver outputs with integrated line adaptation

• Output stages are current limited and short-circuit-proof due to temperature shutdown

• Min. 200 mA output current at 24 V supply voltage

• Low driver stage saturation voltage (< 0.4 V at 30 mA)

• RS422-compatible (TIA / EIA standard)

• Temperature and supply voltage monitor with error messaging

Applications

• Gear wheel sensing

• Pole wheel and magnetic tape scanning

• Magnetic incremental encoders

• Proximity switches

• Two-channel line drivers up to 100 kHz

AMR Linear Position Sensor (Pitch: 2 mm)

Features

• Magneto resistive position sensor based on the AMR effect

• Strong field sensor for 2 mm N/S pole pitch

• One sine/cosine cycle per pole width (averaged using a pair of N/S poles)
