Hall Effect Gear Tooth Sensor CYGTS102DC
with Sinusoid and Square Output Waves
CYGTS102DC Hall Effect Gear Tooth Sensor is designed by using a Hall-Effect sensor element,
which can accurately detect the movement of ferrous metal objects. This specially designed gear
tooth sensor with a biasing magnet and internal denoising filter is sealed in resin for physical
protection and cost effective installation. The CYGTS102DC Sensor works according to the
detection of peak magnetic field change.
This Unit functions under power supply from 4.5VDC to 24VDC. Two signals (one sinusoid wave
and one square wave) are output directly through the output terminal of the operational amplifier.
The sensor will not be damaged if power is inadvertently wired inversely.
