Measuring wheel encoders
DBV50 Core

Your Benefits

  • Compact, space-saving measuring wheel system with low installation depth
  • Large spring travel and high press-on force to compensate for unevenness in the surface being measured
  • Easy and repeatable setting of the spring pretension
  • Prevents system failures by limiting the spring travel to protect the spring from being overloaded
  • Highly adaptable to various applications thanks to a variety of options for mounting the encoder on the spring arm
  • Reliable operation thanks to the reliable encoder with a high radial load
  • Numerous electrical interfaces, facilities for connecting and resolutions


The DBV50 Core measuring wheel encoder is a measuring wheel system for measuring linear movements. It consists of the DBS50 Core incremental encoder, an aluminum measuring wheel with a 200 mm diameter and a spring-loaded arm. The maximum resolution is 0.08 mm per pulse.

The spring arm has a maximum spring travel of 14 mm, a maximum spring force of 20 N and features a convenient pretension setting for repeatably setting the spring pretension. A spring travel limiter protects the spring from being overloaded.

The encoder can be rotated and mounted on both sides of the spring arm; routing of the cable can be adapted to the application. The measuring wheel system can be delivered with numerous electrical interfaces, facilities for connecting and resolutions.
