Tools¶

• Holoseat Test Stand with computer to operate it
• Soldering iron with stand
• Helping hands
• Exhaust fan
• Sensor assembly jig (3D printed tool - provide link)
• Flush snips
• Safety glasses

Materials¶

• Instant/super glue (prefer Loctite Super Glue Ultragel Control)
• Solder
• (1) WSSM-01: TRRS Audio Connector PCB
• (1) WSSM-02: TLE4966L Infineon Technologies High Precsn Hall / Board Mount Hall Effect/Magnetic Sensor
• (1) WSSM-03: Sensor Housing Lower Half
• (1) WSSM-04: Sensor Housing Upper Half
• (1) WSSM-05: 3M 9472LE Tape 1/2" x 1" piece

Safety Issues¶

• Care must be taken when using the soldering iron, the tip is very hot
• Always wear safety glasses while working with soldering irons
• Avoid breathing in the soldering fumes, use a vent or hood if needed to provide adequate ventilation

HS-04: Wheel Speed Sensor Module

Procedure¶

1. Place sensor on TRRS Audio Connector PCB¶

1. Place WSSM-02: TLE4966L Sensor in jig with label facing “out” (toward window in jig)
2. Slide TLE4966L Sensor into jig until its label aligns can be seen through the window in jig
3. Bend TLE4966L Sensor leads down along jig
4. Place TLE4966L Sensor pins through holes in WSSM-01: TRRS Audio Connector PCB with the jack facing up
5. Align TRRS Audio Connector PCB with lip on jig
6. Bend TLE4966L Sensor leads over to fix position of sensor relative TRRS Audio Connector PCB
7. Remove TLE4966L Sensor/TRRS Audio Connector PCB sub-assembly from jig

2. Solder sensor to board¶

3. Verify sensor¶

4. Finish assembly¶
