iC-SM5L
LINEAR AMR SENSOR (5 mm)
Rev B2, Page 2/7
DESCRIPTION
iC-SM5L is a linear position sensor which operates
on the AMR effect (anisotropic magneto resistance)
and has been designed to work with magnetic scales
which have a N/S pole pitch of 5 mm.
width. The absolute magnetic field strength must be
large enough for the sensor to go into saturation and
for the magnetization of iC-SM5L’s resistor stripes to
assume the direction of the outer magnetic fields.
When the Sensor is moved along a magnetic scale
with a N/S pole pitch of 5 mm the two Wheatstone
bridges generate differential sinusoidal output volt-
ages (PSIN - NSIN) and (PCOS - NCOS) phase-
shifted at 90°. One sine/cosine cycle averaged us-
ing a pair of N/S poles is thus produced for a pole
The amplitudes of the differential output voltages are
largely independent of the magnetic field strength
and thus not sensitive to changes in distance.
iC-SM5L is resistant to strong magnetic fields and not
sensitive to external homogenous magnetic fields.
