SMD-04B
Metrology and precision 3-channel Encoder module
The SMD-04B is a miniature, reflective optical incremental encoder head with 3-Channel outputs (2 analog A/B plus Digital Z index) using a 20µ period scale there are 50 periods per mm/1270 periods per inch. Quadrature differential A& B outputs are 4x 200 counts per mm/ 5080 per inch. High bit ADC interpolation enable resolution into the picometer range. SMD-04B low-noise high-precision analog output signals maximize accuracy.
Excellent Lissajous curve with low cyclical errors.
High bit ADC interpolation enable resolution into the picometer range.
A unique LED receptor provide wider tolerance to misalignment, YAW, external contamination and humidity.
Footprint is 5.4x4.3mm and package height 1.0mm with nominal 0.5mm gap to scale for overall height 1.5mm from PCB to scale.
