Gear Tooth Sensor Datasheet
1.0 Description
The Emtron Gear Tooth Sensor is a state-of-the-art flange mounted Hall Effect sensor designed for use in applications where ferrous edge detection / near zero speed sensing is required. Being of a single Hall design, the sensor is immune to alignment issues allowing unlimited mounting positions.
Features & Benefits:
- From near zero speed up to 15 kHz sensing capability
- Capable of operating up to 150ºC
- Plastic flange mount-housing
- Resistant to fuels, solvents, and lubricants associated with vehicles
- RoHS compliant
- Sealed design exceeds IEC60529 IP67 standard for immersion
- Easily customizable connector orientation
- Typical air gap of 1.5 mm (with recommended target type; see drawing)
- Mating connector – Delphi 12162280 (Type 102)
- Mating connector pin – Delphi PN: 12124075 or 12124076
Typical Applications:
- Engine Speed Sensor (both Crank & Sync)
- Transmission Speed Sensor
- Wheel Speed Sensor
- Tail Shaft Speed Sensor

2.1 Dimensions
Gear Tooth Sensor dimensions and connector wiring — inches (mm).
2.2 Installation
For best results, targets should be produced from low carbon cold rolled steel. Other factors that influence sensor performance include gear tooth height and width, space between teeth, shape of the teeth and thickness of the target.
As a general guideline, consider a target within the following minimum parameters.
| Tooth Height (Min) | Tooth Width (Min) | Distance Between Teeth (Min) | Target Thickness (Min) |
|---|---|---|---|
| 0.200" (5.0mm) | 0.100" (2.5mm) | 0.400" (10mm) | 0.250" (6.35mm) |
