Incremental encoders

Your Benefits

  • Wide operating temperature range and high tolerance of shock and vibration reduce machine downtime
  • High resolution provides more precise positioning for applications that require high accuracy
  • Programmable DFS2x encoders simplify machine designs by allowing the same model encoder to be used for different applications
  • Spare parts inventory requirements are reduced because a single programmable DFS2x encoder can be used across a variety of applications
  • Flexible electrical interface configurations reduces the risk that the selected encoder will be incompatible with input electronics


The DFS2x family of products are high-resolution incremental encoders that provide industry standard 2 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 allows you to confidently standardize on a single encoder platform for position sensing across a wide variety of applications while simultaneously reducing your spare part requirements.
