Gear Tooth Speed Sensor for TCS, ESC, Wheel Speed and Transmission Applications
The SSH-G01 is a flange-mount Hall-effect gear tooth speed and direction sensor designed to measure the movement of ferrous gears in demanding automotive and industrial environments. It provides speed and direction feedback, supports near-zero speed sensing, and is designed for harsh areas such as engines, transmissions, brakes and chassis systems.
For engineers comparing speed sensors for Traction Control System applications, wheel speed and direction, Electronic Stability Control, crankshaft/camshaft detection, or transmission speed and direction, the SSH-G01 stands out because it combines:
- Speed and direction feedback
- A/B signal and two-wire current-source output options
- 4–24 Vdc supply range
- IP67 and IP69K sealing
- 50 g shock resistance
- 20 g vibration resistance from 5 Hz to 2,000 Hz
- Custom cable, connector, interface, mounting flange and O-ring possibilities
The SSH-G01 is not simply a “speed sensors.” Its main value is speed plus direction in a rugged gear tooth package, especially where the sensor must survive moisture, vibration, oils, fuels, transmission fluids, brake fluids and other harsh operating conditions.
What is the best use case for the SSH-G01 speed sensor?
The SSH-G01 is best suited for applications that require gear tooth speed and direction feedback from ferrous targets, especially in transmissions, wheel speed and direction systems, traction control, ESC, crankshaft/camshaft sensing, pump speed feedback and hoist or engine speed monitoring. It is a strong choice when a design needs a compact flange-mount sensor with near-zero speed capability, IP67/IP69K sealing and customizable connection options.

The SSH-G01 is directly aligned with transmission speed and direction applications.
For this use case, SSH-G01 has three important advantages:
First, it provides direction feedback, not just speed pulses.
Second, the A/B signal version reaches 40 kHz
Third, it is designed for harsh environments with IP67/IP69K sealing, 50 g shock and 20 g vibration resistance.
Traction control and ESC systems depend on reliable wheel or drivetrain speed feedback. The SSH-G01 is suitable when the application requires near-zero speed sensing and direction feedback from a gear tooth target.
Crankshaft and camshaft applications often require reliable speed or position feedback under high temperature, vibration and fluid exposure.
The SSH-G01 becomes quite attractive when the application also requires direction feedback, IP69K sealing or a customized connector and mechanical interface. Its datasheet lists crankshaft/camshaft as a potential application and highlights resistance to environments such as engines, transmissions, brakes and chassis systems.
| Application | Recommended positioning for SSH-G01 |
|---|---|
| Traction Control System, TCS/TSC | Strong fit where traction control requires gear tooth speed and direction feedback. |
| Wheel speed and direction | Strong fit for ferrous target wheel speed and direction. |
| Electronic Stability Control, ESC | Suitable when ESC input comes from a gear tooth target and direction information is needed. |
| Crankshaft / camshaft | Suitable where direction, sealing or customization are required. |
| Transmission speed and direction gear tooth sensor | Core fit. SSH-G01 is designed around ferrous gear speed and direction sensing in demanding transmission environments. |
| Hoist, pump and engine speed feedback | Suitable for rugged industrial and mobile equipment applications requiring near-zero speed sensing and direction feedback. |
1. It detects both speed and direction
Many gear tooth sensors provide speed pulses only. SSH-G01 provides speed and direction feedback, making it suitable for control systems that need to know not only how fast a shaft or gear is moving, but also whether it is moving forward or reverse.
2. It supports two output architectures
The SSH-G01 is available as:
SSH-G01-002-AB: A/B signal
SSH-G01-002-CP: two-wire current source, CCW
SSH-G01-002-CP-R: two-wire current source, CW reverse
This gives design teams flexibility when integrating the sensor into different ECUs, controllers or harness architectures.
3. It is designed for harsh environments
The SSH-G01 affords resistance to windshield washer fluid, diesel, gasoline, battery liquid, coolant, potash, brake liquid, detergent and engine oil. It also lists IP67/IP69K sealing, salt spray testing, humidity testing, thermal shock and electromagnetic immunity tests.
This makes it especially relevant for applications near transmissions, engines, brakes, chassis systems and outdoor industrial machinery.
4. It can be customized
Customization points include the interface, mounting flange, installed O-ring, form and size, and operating temperature. The datasheet also states that custom design can be provided for form, fit and function, including wire harness and interface connector choice.
Yes. Transmission speed and direction is one of the strongest applications for SSH-G01 because the sensor is designed for ferrous gear tooth speed and direction measurement in demanding environments.

Traditional speed sensing gives control systems the power to measure speed and direction. AI adds the ability to understand what those signals mean by automatically detecting abnormal speed behavior, recognizing operating patterns, filtering signal noise, identifying early signs of mechanical wear, and turning raw speed and direction data into actionable insights for predictive maintenance and smarter vehicle or machine control.
For a gear tooth speed and direction sensor such as the SSH-G01, which provides speed and direction feedback, near-zero speed sensing, and robust operation in applications such as traction control, wheel speed and direction, ESC, crankshaft/camshaft, pump speed feedback and transmission speed and direction, AI can help transform the sensor signal from a simple measurement into a diagnostic and decision-support tool.
In practice, AI can use SSH-G01 output data to detect patterns such as irregular acceleration, unexpected direction changes, gear tooth timing variations, wheel slip behavior, transmission speed inconsistencies or early signs of component degradation before they become visible through standard threshold-based monitoring.
You can check current availability for the SSH-G01 gear tooth speed and direction sensor by using the “Check SSH-G01 Availability” link.
If you cannot find the exact SSH-G01 reference in stock, use the “Search Distributor” link to locate authorized distribution options and send an inquiry for availability, lead time, alternative configurations or project support.
The SSH-G01 gear tooth speed and direction sensor encoder can be configured to meet specific form, fit and function requirements. Configuration possibilities include the cable or connector interface, wire harness, mounting flange, installed O-ring, form and size, and operating temperature. This helps adapt the SSH-G01 to different mechanical layouts, electrical connections and harsh-environment application needs.
