Hollow-Shaft Encoder Breaks Size Barrier March 2002 Issue Published Date: March 01, 2002
Assuming the position as the smallest absolute, multi-turn hollow-shaft encoder on the market, the Model 5882 accommodates shafts up to 12 mm in diameter and measures 40.5 mm deep with a housing diameter of 58 mm. As opposed to mechanical gearing, the encoder employs touch-less electronic gearing with low-resistance circuitry and pulsed read-in and read-out capabilities. The design includes a multi-layer pc board with a LED integrated with a uniquely configured optical ASIC. Other features include an output code with a 25-bit resolution, reset capability, resistance to shock up to 250g/6 ms, and an IP65 rating. A PC-based programming tool, Ezturn, is available that allows users to stock only one type of encoder and individually program it for specific applications.
