Part No: #57213

OVERVIEW

This multi-faceted, Inertial Measurement Unit (IMU) has been designed specifically for motorsport, providing triple axis sensing of G-Force and Gyroscopic measurements. It also provides Compass (magnetic field) measurements.

The sensing range of each sensor has been tailored to suit a wide range of applications that experience high levels of dynamic motion. Each of the three axes (X, Y, Z) is orthogonal to the others, measuring positive and negative forces.

A compact and robust design ensures the 3Force unit is well suited the harsh motorsport environment.

The sensor is capable of detecting the earth's magnetic field, although it is affected by the presence of ferrous objects at very short range.

Note:

The CAN bus speed is selected when the sensor is purchased. It may be changed at a later stage.

CAN BUS ADDRESSES

The sensor transmits three sequential CAN bus messages. The default addresses for the CAN bus messages are:

0x610 - X, Y and Z axis G-Force Data
0x611 - X, Y and Z axis Gyroscopic Data
0x612 - X, Y and Z axis Compass Data

COMPATIBILITY

MoTeC Display Loggers and Enclosed Loggers.

WIRING

The sensor is supplied with a pigtail loom and power is supplied via 5 volts.

The 3Force outputs are generated as messages on the CAN bus. There is no CAN termination resistor in the sensor.

4 Pin Connector

Mating connector # 68054
