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  
• Suitable for most vehicle applications  
• Measuring range 2 Hz to 9 KHz (depending on target)  
• Rugged package with connectorized output  
• Diagnostic detection of sensor power supply  
• Physical protection and cost effective installation.  
• 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.  
Typical Applications  
The compact design and rugged construction make this  
sensor the preferred solution for applications such as :  
• Measuring rpm in gearboxes  
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.  
• Monitoring rpm and position of crankshafts and camshafts  
• Pulse counters  
• Tachometers

WARNING  
MISUSE OF DOCUMENTATION  
• The information presented in this product sheet (or catalogue) is for  
reference only. DO NOT USE this document as product installation  
information.  
• Complete installation, operation and maintenance information is  
provided in the instructions supplied with each product.  
An integrated electronic diagnostics feature enables  
detection of open or short circuits in the power supply line by  
monitoring levels in the sensor output.  
Failure to comply with these instructions could result in death  
or serious injury.
