Model 260 Compact Thru-Bore Encoder

The Model 260’s larger bore (up to 0.625") and low profile make it the perfect solution for many machine and motor applications. Available in two distinct formats – a blind hollow bore and a complete thru-bore – the Model 260 uses EPC’s pioneering Opto-ASIC design.

  • Low profile 1.19"
  • Up to 12 pole commutation
  • Thru-bore and blind hollow bore styles
  • Simple, innovative flexible mounting system
  • Incorporates Opto-ASIC technology
  • CE marking available

Model TR1 Tru-Trac®

The Model TR1 Tru-Trac® linear measurement solution is a versatile option for tracking velocity, position, or distance over a wide variety of surfaces. An integrated encoder, measuring wheel, and spring-loaded torsion arm in one compact unit. The spring-loaded torsion arm offers adjustable torsion load, allowing the Model TR1 to be mounted in almost any orientation – even upside-down.

  • Encoder, measuring wheel & spring loaded torsion arm integrated into one compact unit
  • Spring-loaded torsion arm makes wheel pressure adjustments a snap
  • Easily installed in a vertical, horizontal or upside down orientation
  • Operates over a variety of surfaces at speeds up to 3000 feet per minute
  • Integrated module simplifies your system design, reducing cost
