ATOM Encoder System readhead ATOM2T1-100

ATOM™ is the world’s first miniature encoder with filtering optics, providing improvements in dirt immunity, signal stability and reliability for linear, partial arc and rotary applications. ATOM features a number of other advances that help maintain signal stability, including integral Auto Gain Control and Auto Offset Control, along with a highly reliable IRED light source, making the product suitable for use in applications demanding quality and dependability

The miniature readhead is available in 2 formats: hi-flex cable output or flexible-printed circuit (FPC) output. The FPC version helps reduce overall package size, with a reduced Z-height and easy cable routing. ATOM is available with a range of high-accuracy optical linear, partial arc and rotary scales, including conventional glass spars, ‘unbreakable’ stainless steel tape scales and glass discs. Installation has been simplified by an intuitive set-up LED on the readhead that indicates signal level. Optical reference mark phasing and incremental signal optimisation can be achieved with the simple press of a button. ATOM is suitable for use in a variety of applications that require compact size, including laser scanners, CMM arms, semiconductor manufacturing, compact linear motors/motion stages, small DDR torque motors, galvanometers and microscope stages.
