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.

APPLICATION
In life-support systems, the behaviour of electronic components throughout their working life can be unpredictable.
The use of these devices in support systems can only be permitted when there is no danger to life caused by devices
failing unexpectedly.
