Angle sensor hybrid KM110BH/2130; KM110BH/2190

DESCRIPTION

Sensor module for contactless measurement of angular displacements of strong magnetic fields. The module is a ready-trimmed (sensitivity and zero point) combination of the magnetoresistive sensor KMZ10B and a signal conditioning circuit in hybrid technology. The KM110BH/2130 delivers a linear output signal that is proportional to the direction of the magnetic field. The KM110BH/2190 delivers a sinusoidal signal.
For new design-ins the KM110BH/23 and KM110BH/24 modules are recommended.
