SICK Ltd. launched a new encoder that, when coupled to special evaluation electronics, can offer 30-bit resolution. This level of accuracy is important to those working with and designing systems and machinery that demand high levels of accuracy and repeatability, such as positioning on pan and tilt assemblies and highly accurate azimuth and altitude positioning for telescopes. With a resolution up to 262,144 x 4,096, the encoder is available in single- and multi-turn variants as fully sealed IP65-rated versions or modular designs to enables users to incorporate them into their own housings. A low part count, operating temperature range up to 125 degrees C and high level of shock and vibration resistance widen the application base further. In operation, the encoders are fully absolute, with all multi-turn variants using a gearing system to form positional values--there is no battery buffered memory. Encoders can communicate with the necessary evaluation electronics over distances up to 100m. Output from the evaluation electronics is SSI or Profibus, with DeviceNet, CANopen and Ethernet versions being available very soon.
