PAT9406E1-CVBB
- Supports single-axis tracking and rotation tracking
- Achieves a resolution of 7,110 counts/rev on a 1mm diameter stainless steel shaft
- Enables close proximity surface tracking from 0.5 to 3mm
- Built-in with 3 sleep modes with the lowest sleep current being 3uA
- SMT reflowable 8-pin LGA integrated with VCSEL LASER die
- Shorten shaft overlap length to 1.6mm @ working distance > 1.2mm
- Minimal package dimension: 2.8 x 2.6 x 0.8mm^3
- Ideal for digital rotary inputs on smartwatches, fine-resolution input selectors, and smart dials
