30° and 70° angle sensor hybrids
FEATURES
• Angle measuring range 30° or 70°
• Contactless, therefore wear-free and no microlinearity
problems
• Easy to mount, ready for use
• 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.

EMC RESISTIVITY
The EMC compatibility is dependent on the assembly of the sensors. The EMC resistivity has to be tested in the final
application.

Notes
1. 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.

Notes to the characteristics
1. Refer to Fig.3. The magnetic field Hext = 100 kA/m can be achieved using the magnets listed in Table 1.
2. The sensitivity will change slightly with +0.33% per 10% magnetic field increase if Hext deviates from 100 kA/m.
3. Deviation from best straight line in angle range.
4. Difference in output signal (expressed in degrees) between two zero point (α = 0°) measurements, in which the zero
point is approached from the same side of the measuring range (e.g. cycle: +15°
5. The smallest detectable change of angle ∆α for α = 0° (cycle: 0° ∆α).
