Product data sheet for Fredericks' ±30° RS-485 dual-axis MEMS inclinometer, model 0750-3002-99, with specs, mounting, and RS-485 commands.
This document details the specifications and features of the Fredericks 0750-3002-99 dual-axis MEMS inclinometer, including its ±30° operating range, RS-485 interface, and IP67 rating. It is designed for industrial applications such as construction machinery and structural monitoring. The sensor supports commands for X and Y axis tilt measurements, temperature output, and zero offset calibration.
Mounting requires a flat surface with M4 screws, and calibration is needed for each axis before use. The device operates from -40°C to 85°C and is RoHS compliant. Related products include analog and SPI versions for different applications.

The operating temperature range is -40 °C to 85 °C.
The IP rating is IP67 (excluding connector).
The sensor must be calibrated in each axis so the sensor outputs ‘0’ at the zero position before use.
Available commands include *9914# for X axis output, *9918# for X axis average output, *9924# for Y axis output, *9928# for Y axis average output, *9942# for temperature output, and *9981A25# to change address.
