Hall Sensors Elements NHE Series

Digital Hall sensors as described in the previous pages are
a very convenient magnetic sensor solution because they include
the Hall element, amplifier and the signal evaluation circuit on one
single chip. In some special cases, however, it is necessary to
develop an individual signal evaluation circuit, e.g. if very low electrical power consumption is required. For these applications we
offer Hall elements in the very small SOT-23 housing. In this case
the vertical magnetic field component that is perpendicular to the
PC board is measured. A vertical type is also available which
detects horizontal magnetic field components parallel to the PC
board (NHE529).
