The angle encoder is the core sensing unit in the servo closed loop of robot joints, outputting joint angle and speed signals in real time and directly determining robot positioning accuracy, motion stability, and human-robot collaboration safety.
With vibration and shock resistance, a thin and light structure, and large hollow bore, Magnetic Encoders are widely suited to collaborative robots and industrial robotic arm joints, supporting high-precision robot development.
- Compact internal joint space imposes strict demands on encoder miniaturization and hollow integration
- Vibration and temperature cycling easily cause accuracy drift; human-robot collaboration scenarios require functional safety redundancy
- High resolution and high repeatability requirements, with some applications needing battery-backed multi-turn absolute position detection
- Imported devices have long lead times and high cost, while needing compatibility with RS485, SPI, BiSS-C, and other servo communications
