Encoder Motion Sensing Products

Encoder Products Company Inc. is an industry leader in design of motion sensing products. They produce both incremental and absolute shaft encoders.  Encoder Products offer four solution groups to satisfy all of your positioning needs including:

  • Encoder Motion SensorIncremental Thru-Bore & Motor Mount Encoders
  • Incremental Shaft Encoders
  • Absolute Encoders
  • Linear Solutions Encoders

Incremental encoders can provide a once-per-revolution pulse (often called index, marker or reference) that occurs at the same spot of the encoder shaft revolution.  Incremental encoders are available in two basic output types, single channel and quadrature.  A single channel encoder often called a tachometer, is normally used in systems that rotate in a single direction and requires simple position and velocity information.  Quadrature encoders have dual channels (A and B), phased 90 electrical degrees apart.  These two output signals determine the direction or rotation by detecting the leading or lagging signal in their phase relationship.  Quadrature encoders provide very high speed bidirectional information for very complex motion control applications.

Tru-Trac encoders are perfect for linear applications and can be mounted above or below the moving object.  A spring loaded torsion arm allows the tension on the wheel to be adjusted, so the measurement can be obtained for a variety of different surfaces.

Model LCE encoders are a cost effective linear solution up to 50”.
