Product Overview
The eCoder45 is an ultra-slim absolute magnetic encoder measuring just 2.5 mm in axial thickness with a 45 mm hollow bore and 64 mm outer diameter. Its 20-bit resolution and ±5 arc-second repeatability make it the preferred choice for large-shaft robotics and automation applications where minimal axial space is a hard constraint.
The eCoder45 is a magnetic position feedback device designed for reliable encoder performance in compact robotic and automation assemblies.
Magnetic Encoder Technology
Magnetic absolute encoders provide reliable position feedback without battery backup. The magnetic sensing principle operates in contaminated environments where optical encoders may fail, making them well-suited for robot joint and industrial automation applications.
Battery-Free Absolute
Retains absolute position data across power cycles without battery backup or capacitor.
Magnetic Sensing
Magnetic principle operates reliably in dust, grease, and vibration environments.
High Resolution
High-resolution position data for precise closed-loop robot joint control.
Compact Disc Format
Disc format mounts directly to eRob module output shaft without additional interface.
No Homing Required
Absolute position data eliminates homing sequences after power interruptions.
eRob Compatible
Designed to complement the eRob integrated joint module series.
