Introduction
Dynalabs Inertial Measurement Units are based on triaxial accelerometers and triaxial gyroscopes that are integrated in a single housing. The inertial measurement unit (IMU) is based on proven microelectromechanical systems (MEMS) accelerometers and gyroscopes for detecting the smallest linear accelerations and angular rates. Dynalabs IMUs enable separate analog voltage outputs for all 6 degrees of freedom (DOF). IMUs enable power supply voltage from 6 to 20 VDC. Dynalabs IMUs feature a lightweight, reliable aluminum housing with protection class IP68 and have cable with configurable length and connectors.
DYN-I-8000 sensors offer the following options;
- Custom Cable Length
- Custom Housing Material
- Custom Connector
- Base plate

Operation and Installation
General
The general sensor connector configuration is given below;
Cable Code/Pin Configuration
- Red: V + Power supply voltage +6 to +20 VDC
- Black: Ground Power GND
- X-Axis: Yellow: Signal(+) Positive, analog output voltage signal for differential mode.
- Purple: Signal(-) Negative, analog output voltage signal for differential mode.
- Y-Axis : Blue: Signal(+) Positive, analog output voltage signal for differential mode.
- Green: Signal(-) Negative, analog output voltage signal for differential mode.
- Z -Axis: White: Signal(+) Positive, analog output voltage signal for differential mode.
- Orange: Signal(-) Negative, analog output voltage signal for differential mode
Cable Code/Pin Configuration:
- Red: V + Power supply voltage +5 V to +20 VDC.
- Black: Ground Power GND
- RX: Brown: Gyro Signal X-Axis: Analog output voltage signal for single-ended mode.
- RY : Grey: Gyro Signal Y-Axis: Analog output voltage signal for single-ended mode.
- RZ: Pink: Gyro Signal Z-Axis: Analog output voltage signal for single-ended mode.
- White- Brown: NC Not connected.
WARNING
- Never connect the power supply and/or the power ground to yellow, purple, blue, green, white, orange, brown, grey, and/or pink cables.
- Never connect the power supply to the power ground. Always use a clean power source and check the voltage range.
Sensor Static Calibration Verification
- Using gravity for the accelerometer of the 8000 series IMU, voltage values are measured in the + and – gravity directions, providing a value of ±1 g. The measurement should be made as follows;
- When the acceleration value of 8000 series IMU’s accelerometers is entered into the data acquisition system, the sensor shows +1 g with the effect of gravity, which is in the direction of the axis to be calibrated.
- When the sensor is positioned in the opposite direction to the axis to be calibrated, the arrow shows -1g as shown below under the effect of gravity.
- Using gravity, the voltage values that provide 1 g in the + and – directions are measured and compared with the catalog value. The calibration value should be close to the catalog value with 10% tolerance. Sensor catalog sensitivity values are given in Table 2.
