The DFS2x family of products from SICK are high-resolution incremental encoders that provide industry standard 2 inch and 2.5 inch mechanical interfaces and are available as factory-configured or programmable devices. Factory-configured encoders can be ordered with TTL, HTL, or open-collector outputs as well as integer resolutions from 1 to 65,536 counts per revolution. Programmable encoders allow the user to select the integer resolution and either TTL or HTL outputs. DFS2x encoders incorporate rugged internal technology that allows them to operate over a wide temperature range and tolerate twice the shock and vibration levels of comparable encoders. The flexibility and reliability of these encoders allow users to confidently standardize on a single encoder platform for position sensing across a wide variety of applications while simultaneously reducing their spare part requirements.
