Transmission Rotary Sensor (TRS) | Drive Mode Sensor
TE Connectivity announces new drive mode sensor. The drive mode sensor is a non-contacting sensor that detects drive shaft position in automatic transmissions to support driving efficiency and comfort.

TE Connectivity (TE), a world leader in connectivity and sensor solutions, today announced its new transmission rotary sensor (TRS) with integrated magnet. The non-contacting sensor provides critical information on the current drive-shaft position to confirm the activated drive mode of an automatic transmission, which is required for efficiency- and comfort-related functions such as start-stop.
An integrated magnet in the sensor’s rotor, which is attached to the end of the drive shaft, provides a magnetic field. As the drive shaft rotates within a plus or minus 50 degree-oscillating movement (maximum 359 degrees) the 3D Hall sensor on the printed circuit board reacts to field changes. Over its lifetime the TRS has an accuracy of 1 percent.
The robust, rugged sensor provides a resolution of 12 bit/1 mV with a refresh time of 1 ms to 10 ms (programmable). Output options include analog, digital (SENT), PSI 5 low-current version and PWM (100 Hz – 1kHz). The TRS can be supplied either with the automotive standard board net voltage of 12 volts or with 5 volts and a current of <10 mA. It is certified to Automotive Safety Integrity Level (ASIL) B and is designed for an operating temperature of minus 40 degrees Celcius up to 150 degrees Celcius.
“Our new transmission rotary sensor provides non-contact measurement which is ideal for transmission applications,” said Michael Ludwig, TE senior manager for Global Sensors, TE. “The sensor is a highly reliable, cost-efficient solution. As the measurement is carried out through the die-cast housing, the fully encapsulated sensor element is oil-tight against all transmission fluids.”
TE products connect nearly every electrical function in cars – from alternative power systems to infotainment and sensor technologies.
