Inductive vs Optical Encoders: The Next-Generation Choice for Robot Joints

Analyzing why inductive encoders are becoming the mainstream technology for robot joints in terms of accuracy, environmental robustness and cost.

Compared with traditional optical encoders, inductive encoders are naturally immune to heat, oil, dust and shock, and require no precision gratings or light sources, making them more cost-competitive.

Daozhisen inductive absolute encoders achieve up to 23-bit accuracy with no homing after power loss — ideal for precision servo motors, robot joints and automotive high-speed motors.
