GTN Series
Hall Effect Gear Tooth Sensors
Features
• Digital current sinking output (open collector)
Benefits
• Better signal to noise ratio than variable reluctance
sensors, output amplitude not dependent on speed
• Resistant to damage from incorrect wiring
• Suitable for most vehicle applications
• Physical protection and cost effective installation.
• Allows breakages or short circuits in sensor power supply
to be detected.
• Integrated reverse polarity protection
• Measuring range 2 Hz to 9 KHz (depending on target)
• Rugged package with connectorized output
• Diagnostic detection of sensor power supply
Description
GTN Series Gear Tooth Sensors use a magnetically biased
Hall effect integrated circuit (IC) to accurately sense
movement of ferrous metal targets. This specially designed
IC, together with protection and diagnostic circuitry and a
permanent magnet, is sealed in a rugged probe type
package.
Installation
The sensor is flange mounted with a range of possible
lengths, eliminating adjustment and positioning. Connection
is by AMP Superseal 1.5 Series.
Typical Applications
The compact design and rugged construction make this
sensor the preferred solution for applications such as :
• Measuring rpm in gearboxes
• Monitoring rpm and position of crankshafts and camshafts
• Pulse counters
• Tachometers
Operation
The flux density of the permanent magnet alters when
approached by ferrous metal. This is detected by the Hall IC.
If the sensor is positioned at the circumference of a revolving
gear wheel, for example, it detects teeth and tooth spaces,
supplying a digital pulse output with frequency proportional
to gear wheel speed. Optimum performance is dependent on
the following variables which must be considered in
combination : target material, geometry and speed, sensor/
target gap, ambient temperature and stray fields.
An integrated electronic diagnostics feature enables
detection of open or short circuits in the power supply line by
monitoring levels in the sensor output.
