High-Precision ARS60-AAA00720 Absolute Encoder from SICK

Selling Points

1High Resolution: Up to 15 bits (32,768 increments) for precise positioning.
2Robust Design: IP65-rated enclosure for maximum system availability in extreme conditions.
3Versatile Interfaces: SSI with gray code type or gray capped, and parallel with gray, gray capped, binary, BCD code types.
4Compact Size: Ideal for tight installation spaces with a solid shaft diameter of 6 mm.
5High Repeatability: 0.005° repeatability standard deviation for reliable measurements.
