HG4930 S-Class MEMS Inertial Measurement Unit

The HG4930 S-Class is a micro-electro-mechanical system (MEMS) inertial measurement unit (IMU) designed for applications like camera stabilization, antenna stabilization or gimbal stabilization. It's small, light-weight and low power make it ideal for most applications and it optimizes latency and bandwidth without sacrificing accuracy.

The HG4930 includes MEMS gyroscopes and accelerometers, making it a 6 degrees of freedom (DOF) IMU. In addition, the HG4930 S-Class employs an internal environmental isolation system to attenuate unwanted inputs commonly encountered in real world applications. The internal isolation and other proprietary design features ensure the HG4930 S-Class is rugged enough to meet the needs of the most demanding users.

Three different performance grades of the HG4930 S-Class are available as off-the-shelf items. Honeywell screens and calibrates all of the MEMS inertial sensors utilized in the HG4930 IMU.

The HG4930 S-Class is not ITAR controlled. It's Export Control Classification Number (ECCN) is 7A994.

Frequently Asked Questions

What is the typical lead time for gas turbine overhaul services?

The lead time for gas turbine overhaul services ranges from 6 to 14 weeks, depending on the damage assessment, parts availability, and whether hot-section repairs are required. Expedited options may reduce this by 30%.
Do you provide customizations for legacy turbine control systems?

Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
How often should industrial gas turbines undergo performance testing?

We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
Are your radiation-hardened (rad-hard) semiconductors compliant with MIL-PRF-38535?

All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
What temperature ranges do your military-grade ICs support?

Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Are PMA parts interchangeable with OEM components?

Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
What traceability standards do you follow for aircraft fasteners?

All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
How do you handle urgent AOG (Aircraft on Ground) requests?

AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
