Introduction

ER-MNS-04 Ultra-small Size OEM MEMS North Seeker

Introduction
ER-MNS-04 MEMS North Seeker is designed for high accuracy north finding in challenging environments such as mining. Its ultra-small size and OEM modular design make it ideal for integration into various systems.

It is composed of a three-axis MEMS gyroscope and MEMS accelerometer, it can measure the true north. It has the 5°C to 55°C high quality heading attitude calibration, cost efficient and low power consumption. It can resist harsh environment and is widely used in mining, tunnel construction and other fields.

It takes only a few simple steps to connect the product to your system and obtain the geocaching data without the 15-pin plug provided by our company. The size and weight of our products are significantly reduced by removing the base plate housing.
