iC-Haus iC-MU Magnetic Off-Axis Position Encoders

Introduction

The iC-Haus iC-MU is a magnetic off-axis position encoder IC designed for accurate rotary position measurement. With integrated Hall sensors and support for absolute and incremental encoder outputs, it provides a compact sensing solution for applications that need reliable angular position feedback within a mechanical revolution.

Part Description

The iC-MU is a magnetic position encoder from iC-Haus intended for two-track magnetic scanning. Its integrated Hall sensors detect magnetic field patterns and convert the resulting signals into precise digital position information.

Key capabilities include:

• Absolute position measurement within one mechanical revolution
• 12-bit sine-to-digital conversion
• Two-track magnetic scanning support
• Integrated Hall-effect sensor elements
• Serial communication through SPI, BiSS, and SSI interfaces
• Incremental ABZ output signals for motion-control systems
• Compatibility with single-turn and multiturn encoder designs
• Off-axis mounting capability for flexible mechanical integration

By combining sensing, signal processing, and multiple encoder interface options in one IC, the iC-MU can reduce the need for separate sensor and converter circuitry.
