Scanning For Ideas: Rotating Hall-Effect Sensor
The 9360 noncontact Halleffect rotary sensor from Duncan Electronics, Irvine, Calif. (beiduncan.com), provides 360° of absolute position feedback and infinite rotation.
Output
is analog or PWM
and maximum
rotational speed
is 300 rpm. A
compressionmolded
rotating
neodymium disc
magnet generates
a relatively strong
magnetic field
for reliability and accuracy. And
it makes sealed
connections with
industry-standard
six-pin Packard
Electric Metri-
Pack connectors.
It operates in
temperatures
from –40 to 185°F.
Accuracy is to within
0.6% of full scale at
room temperature
and 0.9% of full
scale over the
entire temperature
range. The sensor
withstands 10-g
vibrations at 20 to
2,000 Hz, and
50 g of shock,
The sensor
measures 25.8
41.1 50.7mm.
