Introduction

Bourns® Type 6002 Non-contacting Steering Angle Sensor is based on two magneto-resistive (AMR) sensor chips. Each of them converts an angle position of a permanent magnet into two analogue signals (one sine and one cosine signal). A highly effi cient algorithm allows for estimating the absolute angular position of a drive shaft that is connected to the device.Specifi cations

• Angle position [degree] = N · 0.1, for 0 < N ≤ 32767 (N - digital value of the message) = (N-65536) · 0.1, for N > 32767 Angle Speed: • Unsigned (char)

• Rotation speed [degree/s] = S · 0.4

Specifi cations are subject to change without notice.

Customers should verify actual device performance in their specifi c applications.

CAN Protocol (Continued)

Rule to build the check sum: Temp_result = lower byte

(Angle position) XOR higher byte (Angle position) XOR (Angle speed) XOR

(Internal status) Check sum = higher nibble

(Temp_result) XOR lower nibble (Temp_result) XOR (Message counter)

The device checks the angular speed

value, which is limited to 1016 degrees per second. If this limit exceeded, the device sends an error message according to the CAN Transmit Message (page 1).
