TPMS OEM Sensors

Schrader (Electronics) originally developed Tire Pressure Monitoring System (TPMS) technology in the early 1990s. From the original TPMS sensors built into aluminum clamp-in valves, to today’s patented and programmable sensors and rubber snap-in valves, Schrader has established itself as the global market leader by providing easy-to-use TPMS technology for OEMs as well as the service and repair community. In fact, over 54% of global vehicle platforms carry Schrader TPMS technology off the assembly line, with over 160 million Schrader sensors on the road today.

The battery-powered TPMS sensor monitors a vehicle’s tire pressure, whether the vehicle is stationary or in motion. The sensor is attached to the vehicle’s tire valve stem, with the sensing electronics inside the tire. The sensor periodically measures tire pressure and temperature and transmits this information to an on-board receiver via radio frequency (RF) technology. The receiver decodes the RF signals, and alerts the driver if any of the vehicle’s tire pressures drop below a pre-programmed threshold.

Applications: Tire pressure sensor mounted in a wheel rim valve hole to monitor tire pressure and warn the driver through a dashboard low-tire light, instrument panel text message, and/or chime. Different sensor variants are used for different OEMs.

Components: Rubber or aluminum valve stem, plastic cap, electroless nickel-plated valve core, plastic enclosure containing sensor electronics

Features Set
  • Sensor monitors tire pressure and temperature and transmits these to an on-board RF receiver
  • System warns the driver of slow pressure loss before it becomes dangerously low and the vehicle becomes unsafe to drive
  • Replacement sensors can be programmed to behave like your car’s original parts, covering a wide array of vehicle makes and models
Value Proposition
  • Patented snap-in technology offers excellent corrosion resistance and easy installation
  • Sensor battery life: 10 years or over 100,000 miles
  • Systems available to automatically relearn new tire positions after tire rotation, so no reprogramming is needed when wheels/tires are rotated
Technical Specifications
  • Pressure accuracy: ± 5% even at extreme temperatures (-40°C to +100°C)
  • 315 or 433MHz sensors available for worldwide compatibility
  • Sensor RF transmissions are reduced when the vehicle is stationary to conserve battery power
