The Sensing and Control business of Honeywell has introduced the GTN Series, a packaged gear tooth sensor offering proven reliability and valuable diagnostics for speed sensing applications in heavy duty vehicles which require electronic control.

Designed for long service life in harsh operating environments, the GTN Series combines the reliability of Honeywell's automotive gear tooth sensors with a rugged packaging resistant to vibration, shock, EMI and washdown.

Typical applications include measuring rpm in gearboxes, monitoring camshaft and crankshaft speed and position, and measuring transmission speed.

GTN sensors use a magnetically biased Hall effect integrated circuit to accurately sense movement of ferrous metal targets.

This specially designed IC, together with discrete protection, diagnostic circuitry and a permanent magnet, is sealed in a rugged, probe style housing.

The probe, which is available in several lengths, is designed to be flange mounted and has an integrated connector for ease and speed of installation.

The integral electronic diagnostics feature enables detection of open or short circuits in the power supply line by monitoring levels in the sensor output.

Sealed to IP67 (and to IP6K9K, when fitted with the appropriate connector assembly), the GTN Series offers all-round high environmental performance gear tooth sensing.

The sensor has a digital, current sinking output (open collector) and a gear speed measuring range of 2 Hz up to 9 KHz (depending on target).

Available with either a 12V or 24V power supply, the device has a nominal supply voltage of 8 - 16 V or 21 - 32 V.

The operating temperature is -40 to 125 C.
