BHSENS TMSS5B4 TPMS Sensor
Introduction
The TPMS sensor is mounted in the vehicle’s wheels with the help of special
TPMS valves. The sensor measures pressure, temperature, and acceleration in
the tire and transmits the measuring data cyclically via the air interface to
the TPMS Receiver. The TPMS ECU will analyze the data on the tire pressure and
temperature and location for each wheel on the vehicle. Based on the data from
the wheel sensors and an algorithm developed, the TPMS ECU will report
warnings and tire pressures over the CAN bus to the drivers display.
Installation
The Huf handling guide is to be observed for reliable installation in the
vehicle. Here you find instructions for proper mounting positions on the
vehicle and the handling of the wheel sensors.

Product mounting options
The TPMS Sensor S5.xF will be produced in different housing options to adapt the sensor housing to different valve types. Therefore, the plastic housings differ only in outer contour, the inner contour with PCBA & battery are identical. The valve interface design (plastic material) does not impact RF performance and EMC behavior. To fulfill customer needs, there are also different color options available.
Sensor electronic design
The electronic design of the TPMS Sensor S5.F consists of the PCBA with
electronic components and the connected lithium battery CR2032. PCBA, battery,
plastic housing and potting material create the EMC-relevant unit of the
device. The outer shape of the plastic housing has no further influence on the
EMC behavior of the wheel electronics.
Metal valves with ball calotte
The second one (S5.5) have additional small housing feet.
Metal valve with Ratched design
The second one (S5.x) have additional small housing feet.
Rubber valve with radial OR axial fastening screw
There are two mounting options for rubber valves.

Operating modes
The TPMS Sensor operates in various modes depending on external conditions. Additional test modes can be activated by LF commands by the use of a workshop tester or in production line. The TPMS sensor includes already all possible application cases in its program memory and is configured once by a professional installer. Upon manually activated LF request (through special configuration tool at a vehicle dealership), the EUT responds with a single RF transmission (sensor type information). In the second step the tool will send the configuration data on LF and the EUT will respond with a single confirmation transmission. Now the TPMS sensor is configured for the target vehicle application. When the EUT is mounted in the vehicle tire in the worst case, periodically RF transmission where the duration of each transmission is always less than 1 second and the silent period is at least 30 times the duration of the transmission, and never less than 10 seconds. In the case of an emergency condition (rapid pressure loss), the devise will transmit tire pressure and temperature information throughout the duration of the condition. The CW lower and CW upper modes represent the upper and lower frequencies of FSK modulation.
