Gurley Precision Instruments Absolute Encoder with SSI Output M58

Major Features and Advantages: Up to 20-bit single-turn resolution available Up to 44-bit (20-bits/turn + 24-bit turns) gearless multi-turn resolution available Standard synchro flange SSI interface standard (RS-485) - 4 MHz clock frequency Accuracy: +/- 30 arcsec The Model M58S with SSI output is a heavy-duty absolute rotary encoder with optical technology and standard SSI (RS485) interface, used in a wide variety of position sensing applications for measuring angles and distances. It is available as a single-turn encoder with up to 20 bits of resolution (2,097,152 steps per revolution), or as a standard multi-turn with a range of 20-bit words/turn + 24-bit turns. The optical technology and magnetic sensors (for counting turns) allow the encoder to be gearless. A back-up battery is located inside the encoder and assures true absolute position even power is disrupted.
