Precision Encoder module
Discontinued Products are limited to existing inventory.
The SMD-01 reflective optical encoder is the best starting point for high resolution nanometer applications as its low noise and low distortion output enable interpolation using 12-16 bit A/D conversion and single digit resolution. A unique led receptor array provide wider tolerance to misalignment, YAW, external contamination and humidity SMD-01 makes it easier to manufacture precision encoders and achieve longer service life. Its small 5.4x4.3 mm footprint and 1.68 mm height allow ever smaller encoders .

Using a 20µ period the SMD-01 boasts native 5µ resolution; Seiko NPC SM3470 and SM3471 interpolators offer factors of 20x and 8x to support applications better than 5µ to 0.1µ

VC America supplies scales in various sizes and including custom sizes. Contact us with your requirements.
