The Honeywell GTN Series Gear Tooth Sensors are designed for applications requiring precise measurement of gear tooth movement. These sensors employ a Hall effect IC within a rugged probe package, offering a digital current sinking output and protection against reverse polarity. They are suitable for measuring RPM in gearboxes, monitoring crankshaft and camshaft position, and serving as pulse counters or tachometers. The sensor's flange mounting and connectorized output simplify installation and ensure reliable operation across a wide range of temperatures and vibration conditions.
