The SMD-01B is a miniature, Optical reflective incremental encoder head module with 2-Channel analog A/B outputs.
SMD-01B 20µ period combined with interpolation circuit can achieve subnanometer resolution. And SMD-01B low-noise low distortion analog output maximize accuracy.
A unique LED receptor provide wider tolerance to misalignment, YAW, external contamination and humidity. This reduces assembly process workload required for a high-precision encoder, and simultaneously supports miniaturization and high accuracy requirements.
