HMC1501 / HMC1512
H
igh resolution, low power MR sensor
capable of measuring the angle
magnet with <0.07擄 resolution.
Advantages of measuring field
direction of a magnetic field from a
direction versus field strength include:
insensitivity to the tempco of the
magnet, less sensitivity to shock and
vibration, and the ability to withstand
large variations in the gap between
the sensor and magnet. These
sensors may be operated on 3 volts
with bandwidth response of 0-5 MHz.
Output is typical Wheatstone bridge.

FEATURES AND BENEFITS
No Rare Earth Magnets
Unlike Hall effect devices which may require samarium cobalt or similar 鈥渞are earth鈥?/div>
magnets, the HMC1501 and HMC1512 can function with Alnico or ceramic type magnets.
HMC1501鈥擜ngular range of
鹵45擄
with <0.07擄 resolution.
HMC1512鈥擜ngular range of
鹵90擄
with <0.05擄 resolution.
Linear range of 8mm with two sensors mounted on two ends; range may be increased
through multiple sensor arrays operating together.
Unlike incremental 鈥渆ncoding鈥?devices, sensors know the exact position and require no
indexing for proper positional output.
No moving parts to wear out; no dropped signals from worn tracks as in conventional
contact based rotary sensors.
Available in an 8-pin surface mount package with case dimensions (exclusive of pins), of
5mm x 4mm x 1.2mm total mounting envelope, with pins of less than 6mm square.
Full Scale output range of 120mV with 5V of power supply.
