Dayton, O.— SR-50 Series, single-turn and multi-turn motor feed back system offers a compact 50 mm housing, and is said to be the smallest, smart-absolute multi-turn encoder available. SR-50 offers increased accuracy down to ±5 arc-sec, and high resolutions to meet the increasing demands of digital drives for reduced update times in the 50-200 µsec range. As a result of fine resolutions for the dynamic speed, position loops to 8 million counts, and a 12-bit A/D conversion of the 1,024 analog sin/cos signals, control engineers can realize absolute feedback at the level of incremental feedback. www.stegmann.com Stegmann
