DESCRIPTION The KM110BH/2430 KM110BH/2430 and the KM110BH/2470 KM110BH/2470 are sensor modules for contactless measurement of angular displacements of strong magnetic fields. The modules are a ready-trimmed (sensitivity and zero point) combination of a magnetoresistive KMZ sensor and a signal conditioning circuit in hybrid technology. The KM110BH/2430 KM110BH/2430 delivers a voltage output signal which is a linear function of the direction of the magnetic field. The KM110BH/2470 KM110BH/2470 delivers a sinusoidal voltage output signal. The modules can be used for contactless angle measurement. 1 2 3 MBD897 MBD897 PINNING PIN SYMBOL DESCRIPTION 1 GND ground 2 VCC DC supply voltage 3 VO output voltage Fig.1 Simplified outline.

For operations above Toper = 100 °C, maximum VCC derates linearly from 16 V to 5 V at Toper = 125 °C. 2. If pin 3 is shorted to either pin 1 or pin 2, a current may flow permanently, without damaging the device. 1996 Nov 08 3 Philips Semiconductors Preliminary specification KM110BH/2430 KM110BH/2430; KM110BH/2470 KM110BH/2470 30° and 70° angle sensor hybrids CHARACTERISTICS Tamb = 25 °C; VCC = 5 V; RL = 1.7 k and a homogeneous magnetic field Hext = 100 kA/m in the sensitive layer of the KMZ sensor, unless otherwise specified.
