Non-Contact Rack Gear Detection Sensors
Single channel or quadrature Hall effect gear tooth sensors can track the movement of a rack gear passing their face to monitor speed, or track the relative position of the rack gear.
Rack Gear Detection
Hall Effect Rack Gear Detecting Speed Measurement Sensors (RackDS)
Hall Effect Rack Gear Detecting Sensor for Monitoring Speed and Direction (RackSD)
Hall Effect Rack Gear Detecting Sensor for Counting Tracking (RackDQc)
Hall Effect Rack Gear Detecting Sensor for Position Tracking (RackDQc)
Hall Effect Rack Gear Detecting Sensor for Monitoring Alignment (RackDQc)
Single Output Rack Gear Detecting Sensors
For rack gear sensing applications where the direction of movement does not matter we offer the following product lines.
- DS type Single Channel Gear Tooth Sensors provide one pulse per tooth from rack gears. These sensors are true zero speed Hall Effect Sensors that work up to 10 KHz frequency.
- DSO type Single Channel Target Tracker Sensors provide one pulse per tooth from rack gears. These sensors do not require a specific orientation to the gear and work up to 15 KHz frequency. These sensors are also capable of tracking rack gears with missing teeth and other steel targets.
Multiple Output Rack Gear Detecting Sensors for Count with Direction
For applications where direction the rack gear is moving is monitored along with the speed or a count of the teeth we offer the following product lines.
- DQ type Quadrature Gear Tooth Sensors provide two pulsing outputs that are out of phase. By comparing which output detects the tooth of the rack gear first a tachometer or counter can monitor the direction of movement along with a speed or increasing/decreasing count.
- SD type Speed and Direction Gear Tooth Sensors provide one pulsing output for monitoring speed or tracking the position along the rack gear with a second output that switches between a high and low state dependent on the direction of movement.
- SDQ type Speed and Direction Quadrature Gear Tooth Sensors provide both the two out of phase pulsing outputs of Quadrature Sensors and the high/low output of the Speed and Direction Sensors into a single sensor with three total outputs.
To learn more about selecting speed sensors, selecting or designing rack gears as targets, and the importance of the gear pitch when using Quadrature or Speed/Direction sensors check our Application Notes for more information.

- DS type Single Channel Gear Tooth Sensors provide one pulse per tooth from standard gears. These sensors are true zero speed Gear Tooth Sensors that work up to 10 KHz frequency.
- DSO type Single Channel Target Tracker Sensors provide one pulse per tooth from standard gears. These sensors do not require a specific orientation to the gear and work up to 15 KHz frequency. These sensors are also capable of tracking gears with missing teeth and other steel targets.
