Incremental Optical Encoder

Renishaw Inc.Request Info

Atom, Renishaw Inc.’s new noncontact optical linear and rotary incremental encoder, combines miniaturization with dirt immunity and signal stability for applications including laser scanning, precision microstages, semiconductors, medical, DDR (direct-drive rotor) motors, microscopy, scientific research, and space-critical motion control, inspection and metrology.

The 6.7 × 12.7 × 20.5-mm read head includes a setup LED to allow quick and easy installation and an autocalibration routine to enable faster optimization. The read head is available with either high-flex cable or flexible-printed circuit (FPC) output, in both 20- and 40-µm scale options.

The device offers analog speeds to 20 m/s (29,000 rpm on a 17-mm disk) and digital resolutions to 1 nm when used with the company’s interpolation electronics. A variety of scales are available, including industry-standard stainless steel tapes, linear glass spars and rotary glass disks from 17 to 108 mm in diameter.
