|SMD-01 Optical Encoder Module: Micron to nanometer resolution and accuracies with small footprints are here now.|
SMD-01 Wide angle optical receptors and unique design improve tolerance to angle variation and contamination of dust, fingerprints and moisture (fogging). And lower manufacturing cost.
A 20µ (micron) period provides 5µ native resolution; dedicated Interpolation IC’s efficiently improved resolutions from 1µ to 0.1µ (see Seiko NPC SM3470BB 4x4mm IC) and customer designed high-bit A/D extend resolution to nanometers and achieve phenomenal accuracies via their post processing techniques. Operates at 5V or at 3.3V.
To complement the encoder module, VC America supplies:
- Precision glass scales with option to match environment and application resolution and accuracy.
- Interpolation IC. SM3270AB 4x4mm package
- Precision low jitter and long lifetime clock oscillators
- Application board support for vetting encoder modules
