MRM60 IMU

Product catalog summary

Overview: The MRM Analog 60 IMU is a high-performance analog Inertial Measurement Unit (IMU) designed for various applications including automotive testing, railway motion monitoring, and platform stabilization. It features a non-ITAR commercial MEMS analog output with a signal output swing of ±5 or ±2.5 volts.

Specifications:

Low gyro noise of < 0.0016°/sec/√Hz and low accelerometer noise of < 0.04mg/√Hz.
In-run gyro bias stability of 3°/hour with full temperature compensation from -40°C to +85°C.
Compensated misalignment of 1/2 mrad and g-sensitivity < 0.001°/sec/g.
Input power range from +7 V to +36 V, with a lightweight design of less than 120 grams.
Wide sensor bandwidth of 250 Hz with bandwidth filtering capability.
Vibration resistance of 8gRMS and shock resistance up to 600g’s.
Equipped with 6 internal temperature sensors and self-test functionality.

Electrical and Mechanical Details:

Connector: M83513/03B03N with specific pin assignments for power, ground, and signal outputs.
Analog signals are ±5 volts full scale for -100 models and ±2.5 volts for -250 models, with load requirements of > 5 kΩ and < 100 pf.
Scale factor and error percentages are specified for different ranges and models.
Operating temperature range from -40°C to +85°C and non-operating range from -55°C to +85°C.
Power consumption is 900 mW typical and 1000 mW maximum.
Dimensions: 1.975 x 1.77 x 1.515 inches (5.3 in³) or 5 x 4.5 x 3.85 cm (87 cm³).
Mounting with 4 No.8 or M4 screws.

Performance and Reliability:

High MTBF of 19,518 hours based on MIL-STD-217F standards.
Start-up time of less than 0.25 seconds.
Precision alignment and sensor resolution with a bias over temperature of 1σ.
