DISCRETE SEMICONDUCTORS DATA SH EET KM110BH/2430; KM110BH/2470 30° and 70° angle sensor hybrids Preliminary specification Supersedes data of November 1994 File under Discrete Semiconductors, SC17 1996 Nov 08 Philips Semiconductors Preliminary specification 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 • 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.
