Piher designs and manufactures contactless position and speed sensing solutions for transmission, drivetrain and electrified powertrain applications in cars, trucks, buses, off-highway vehicles and heavy-duty platforms.
Our Hall-effect and inductive sensor technologies support accurate feedback for gear position, shifting fork position, PRNDL, park lock, piston stroke, clutch position, input speed, output speed and vehicle speed. We work with OEMs and Tier 1 suppliers to develop robust, application-specific sensing solutions for demanding environments where vibration, temperature, packaging, EMC, safety integrity and long lifecycle performance matter.
We manufacture a variety of contactless position and speed sensors for transmission applications in cars, trucks, buses and heavy vehicles. Together with our clients we develop the right solution with safety integrity levels up to ASIL-D to meet even the most demanding requirements.

TRANSMISSION SPEED SENSORS
Our Hall-effect transmission speed sensors provide accurate information on input, output and vehicle speed and transmit this information to the vehicle control unit.
Piher Hall-effect speed sensors provide input speed, output speed and vehicle speed feedback for transmission control systems. They are designed to support accurate signal detection in demanding vehicle environments and can be adapted to specific packaging, connector and signal requirements.
TRANSMISSION POSITION SENSORS
Our contactless position sensors based on Hall-effect or inductive technology provide accurate information on gear position, shifting fork position, PRNDL, park lock position, piston stroke and clutch position.
Piher contactless position sensors use Hall-effect or inductive technology to provide reliable feedback in transmission and drivetrain systems. They can be developed for rotary or linear movement, with mechanical integration, electrical interface and output signal adapted to the customer’s application.
Typical use cases include gear position, shifting fork position, PRNDL, park lock, piston stroke and clutch position.
