The DSC sensors are a combination of lateral acceleration sensor and yaw-rate sensor. The DSC sensor consists of:

• Housing cover
• Board with electronic evaluation unit for converting signals
• Sensor electronics:

  The sensor electronics consists of 2 piezoelectric acceleration sensors. A spring-mounted weight is hung in the measuring cell of the acceleration sensor.

• Damper to prevent mechanical overstressing
• Housing with connector

Technically, the two DSC sensors are virtually identical. DSC sensor 2 has an extra terminating resistor. The two DSC sensors have different part numbers. In addition, the DSC sensors make use of a different identifier in the CAN bus. This excludes the possibility of confusing the DSC sensors.
