SCH1633-D01 is a Murata automotive-grade 6-axis Inertial Measurement Unit (IMU), integrating a 3-axis gyroscope and a 3-axis accelerometer.

1. Product Overview

SCH1633-D01 is an automotive-grade 6-axis Inertial Measurement Unit (IMU) manufactured by Murata. It integrates a 3-axis gyroscope and a 3-axis accelerometer based on MEMS capacitive technology, housed in an SOIC24 package. Certified to AEC-Q100 Grade 1 automotive standards and compliant with ISO 26262 functional safety ASIL-B, it is Murata’s new-generation high-precision gyroscope for vehicle navigation.Function: It captures real-time equipment attitude, angular velocity and acceleration data to support dead reckoning, positioning, attitude correction and multi-sensor fusion.

2. Core Electrical & Physical Specifications

2.1 Package Dimensions

12mm × 14mm × 3mm, SOIC-24 surface-mount package, compatible with SMT soldering, supplied in tape-and-reel form.

2.2 Measurement Ranges

• Gyroscope: Default ±300°/s, software-switchable to ±125 °/s or ±62.5 °/s

3.4 High-End Commercial Cleaning Robots (Key Pitch for Floor Cleaning Robot Customers)

Comparison: SCH1633-D01 vs Consumer-Grade SCH16T

• SCH16T: For industrial and household sweeping & washing robots (consumer-grade, -40℃~85℃ operating range, no automotive functional safety certification, lower cost)

• SCH1633-D01: Automotive-grade, exclusively designed for high-end commercial sweepers, autonomous floor scrubbers and vehicle-mounted cleaning robots (models with autonomous driving, extended GPS-denied cruising and outdoor garage operation capabilities)

Cleaning Equipment Application Scenarios

• Autonomous navigation and return-to-charge positioning for large commercial sweepers and unmanned scrubbers deployed in shopping malls and hotels

• LiDAR SLAM-enabled devices supporting long-duration offline cruising, enabling high-precision mapping without Wi-Fi or GPS coverage

• Vehicle-mounted cleaning machines and outdoor garage sweepers (wide temperature tolerance from -40℃ to 110℃)

3.5 Other Extended Applications

• Inclination monitoring for bridges and tower cranes, attitude control for construction machinery, high-precision surveying and positioning equipment
