• Analog voltage output signal
• Operating temperatures up to 125 °C
andbook, halfpage
• Precision of ± 0.5° in the temperature range
(−15° ≤ α ≤ +15°)
• EMC resistant
• Sample kit with magnet available.
DESCRIPTION
The KM110BH/2430 and the 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 delivers a voltage output signal which
is a linear function of the direction of the magnetic field.
The KM110BH/2470 delivers a sinusoidal voltage output
signal. The modules can be used for contactless angle
measurement.
