Honeywell GTN1A112 Hall effect gear tooth sensor Datasheet

GTN Series
Hall Effect Gear Tooth Sensors
Features
Benefits
• Digital current sinking output (open collector)
• Better signal to noise ratio than variable reluctance
sensors, output amplitude not dependent on speed
• Integrated reverse polarity protection
• Resistant to damage from incorrect wiring
• Measuring range 2 Hz to 9 KHz (depending on target)
• Suitable for most vehicle applications
• Rugged package with connectorized output
• Physical protection and cost effective installation.
• Diagnostic detection of sensor power supply
• Allows breakages or short circuits in sensor power supply
to be detected.
Description
Installation
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.
The sensor is flange mounted with a range of possible
lengths, eliminating adjustment and positioning. Connection
is by AMP Superseal 1.5 Series.
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.
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
