SD101201 GEARTOOTH SPEED AND DIRECTION SENSOR
GEARTOOTH SPEED AND DIRECTION SENSOR
SD101201
Circuit protected, Hall-effect speed and direction sensor
Description
The SD101201 is a speed and direction sensor designed to
detect the speed and direction of moving gear teeth. The
speed and direction outputs are open collector transistors.
One hall effect sensor is used to detect the speed of the gear
tooth and the other is used to detect the direction of
movement.
Features and Benefits
 Orientation sensitive
 Mates with Delphi Metri Pack 150.2 Series #12162833
and Terminal Number 12124075
 Operating temperature range -40°C to +125°C
 Near zero speed sensing capability
Applications
 Wheel speed and direction
 Hoist speed and direction
Specifications
Note: A pull up resistor is required between power and each output. Resistor value is dependant upon input voltages.

Operation: When sensing the leading edge of a tooth the Speed Output goes high (ON), and goes low (OFF) on the lagging
edge of the tooth when run against the standard ZF product gear tooth sensor target. The direction of movement is latched on
the leading edge of the speed sensor. The direction Output goes high (ON) for clockwise rotation and low (OFF) for
counterclockwise rotation. The state of the Direction Output always leads the rising edge of the speed output.
