About these encoder systems

ATOM DX™ A4 banner

Open optical encoders

Robust and high-performance linear and rotary position measurement using a finely graduated scale and a compact optoelectronic readhead that converts motion relative to the scale into position data.

  • Incremental and absolute position measurement available
  • Non-contact design - zero hysteresis and no mechanical wear
  • Robust optical design - high immunity to dirt, dust and scratches without compromising signal integrity

Enclosed optical encoders

Exceptionally robust design for use in harsh industrial environments where high performance position measurement is required. Finely graduated stainless steel scale combined with sealed optoelectronic readhead converts motion relative to the scale into position data.

  • Absolute technology – precise, reliable and proven
  • Non-contact design – lower hysteresis and no mechanical wear
  • Uniquely sealed – greater resistance to contamination by fluids, swarf and other debris

RLE laser interferometer encoder system

Laser encoders

Laser encoders combine the measurement and positioning performance expected from a displacement interferometer, with the ease of installation and use associated with a traditional tape or glass scale based encoders.

  • High measurement resolution
  • Low Sub-Divisional Error (SDE)
  • Flexible remote detector heads with fibre based beam delivery
  • Versatile configuration with RMAP-3 periscope to measure linear, pitch and yaw
  • Reliable with long service life

Magnetic encoders

Linear and rotary position measurement at low-cost, with high reliability and capable of operating in harsh environments.

  • Incremental and absolute position measurement available
  • Non-contact design ensures no mechanical wear
  • Robust magnetic position sensing technology provides excellent resistance to most forms of contamination
