HEIDENHAIN and ACU-RITE Incremental Linear Encoders

for DRO applications


HEIDENHAIN have a wide range of linear encoders to suit any application - for different display steps, installation space, and traverse lengths.

The linear encoder measures the exact position of an axis directly at the machine slide, and as a result any backlash in the machine has no effect on the measuring result.


  • Robust, vibration resistant, and durable
  • Sealed aluminium housing with flexible sealing lips to protect against ingress of coolant and swarf
  • Non-contact scanning process, virtually eliminating wear
