Analog Devices Inc. EVAL-XLMOUNT1

Overview

EVAL-XLMOUNT1 from Analog Devices is a precision-machined aluminum mounting block with a central 0.2-inch-diameter threaded hole and 0.38-inch lip, designed to rigidly secure accelerometer breakout boards (e.g., EVAL-ADXL100XZ, EVAL-ADXL35XZ, EVAL-ADXL37XZ) to vibration sources for high-fidelity mechanical evaluation. It delivers ±1.5 dB amplitude flatness up to 20 kHz and supports attachment across five orthogonal faces.

For engineers reviewing the EVAL-XLMOUNT1 datasheet, EVAL-XLMOUNT1 pinout, EVAL-XLMOUNT1 application, or EVAL-XLMOUNT1 equivalent, this mechanical evaluation mount enables controlled frequency-response characterization, high-frequency event capture, and multi-axis orientation testing of MEMS accelerometers in condition-based monitoring and structural health applications.

Technical Context

The EVAL-XLMOUNT1 is a passive mechanical interface-not an electronic component-engineered to minimize parasitic resonance and maximize mechanical coupling between the acceleration source and the mounted sensor board. Its aluminum construction, mass distribution, and lip-and-hole geometry suppress modal distortion below 20 kHz.

Mounting fidelity is maintained via a #10 machine screw through the central 0.2″ hole into the excitation source, while four included 4-40 screws affix compatible breakout boards (EVAL-ADXL100XZ, EVAL-ADXL35XZ, EVAL-ADXL37XZ) to any of five faces-enabling X/Y/Z axis alignment without reorientation of the test fixture.

FAQ

What is the primary function of the EVAL-XLMOUNT1?

The EVAL-XLMOUNT1 is a mechanically optimized aluminum mounting block-not an electronic device-that secures accelerometer breakout boards to vibration sources. Its purpose is to ensure high-fidelity mechanical coupling for accurate frequency-response evaluation up to 20 kHz. The EVAL-XLMOUNT1 achieves ±1.5 dB flatness in that range by minimizing resonant modes and parasitic damping, making it essential for validating MEMS accelerometer performance in lab and field-deployable CbM systems.

Which accelerometer evaluation boards are compatible with the EVAL-XLMOUNT1?

The EVAL-XLMOUNT1 is explicitly designed for use with EVAL-ADXL100XZ, EVAL-ADXL35XZ, and EVAL-ADXL37XZ breakout boards. These boards feature standardized mounting patterns that align with the five-face geometry and 4-40 screw holes of the EVAL-XLMOUNT1. Compatibility is mechanical-not electrical-and no adapter or modification is required when using these designated ADI evaluation boards with the EVAL-XLMOUNT1.

Does the EVAL-XLMOUNT1 include mounting hardware?

Yes, the EVAL-XLMOUNT1 package includes the aluminum mounting block and four 4-40 screws for attaching compatible accelerometer breakout boards. It does not include the #10 machine screw needed to mount the block itself to the vibration source-the user must supply that separately based on their fixture's threading and torque requirements. All hardware is specified in the official Analog Devices documentation for the EVAL-XLMOUNT1.

How does the EVAL-XLMOUNT1 improve accelerometer test accuracy?

The EVAL-XLMOUNT1 improves test accuracy by eliminating mounting-induced resonance and phase distortion. Its 6061-T6 aluminum construction, lip-and-hole geometry, and mass-tuned design deliver ±1.5 dB amplitude flatness from DC to 20 kHz-critical for capturing true high-frequency response of MEMS accelerometers like those on EVAL-ADXL35XZ. Without the EVAL-XLMOUNT1, adhesive or non-optimized mounts introduce roll-off and peaks that corrupt calibration data.

Can the EVAL-XLMOUNT1 be used with non-Analog Devices accelerometers?

The EVAL-XLMOUNT1 has no electrical interface and functions solely as a mechanical mounting platform. While its physical dimensions and screw pattern are optimized for ADI's EVAL-ADXL100XZ/EVAL-ADXL35XZ/EVAL-ADXL37XZ boards, third-party breakout boards with matching 4-40 hole spacing and footprint may be mounted-but mechanical fidelity (e.g., ±1.5 dB flatness to 20 kHz) is only guaranteed when used with the ADI boards specified in the EVAL-XLMOUNT1 documentation.
