SMD-01B
[Reflective incremental Optical Encoder]

High-precision Encoder IC, achieving better than submicron resolution and miniaturization, ideal for embedding in applications.

The SMD-01B is a miniature, reflective optical encoder head that incorporates a LED and high-precision analog amplifier. It generates low-noise high-precision analog signals, due to the unique semiconductor process used to fabricate the CMOS amplifier, and achieves better-than-submicron high resolution, in combination with an interpolation circuit.

It reduces signal degradation caused by errors in mounting position to a minimum, greatly reducing the assembly process workload required for a high-precision encoder, and simultaneously supports the miniaturization and high accuracy requirements of customer’s products.
