Incremental rotary encoder ATOM DX™ RCDM

opticalnon-contactdigital output

What is ATOM DX? The ATOM DX encoder series is Renishaw's smallest incremental optical encoder with digital output direct from the readhead. It provides positional feedback, onboard interpolation and filtering optics all in a miniature package. Detailed diagnostic information can be accessed by using the optional Advanced Diagnostic Tool ADTi‑100 and ADT View software for in‑field diagnostics, fault finding and to aid optimisation of encoder set-up in even the most demanding applications. The ATOM DX encoder also offers resolutions down to 2.5 nm with a wide range of configurations. ATOM DX is supplied in cabled and top exit variants with either 20 µm or 40 µm scale options. What is RCDM disc? RCDM is a one-piece glass disc featuring graduations marked directly onto its face and a single reference mark position and optical alignment band. The optical alignment band can be used to minimise alignment errors and improve installed accuracy. Two versions are available, with either 20 µm pitch or 40 µm pitch incremental graduations, in a range of sizes (20 µm: Ø30 mm to Ø108 mm, 40 µm: Ø17 mm to Ø108 mm). The non-contact format eliminates backlash, shaft wind-up (torsion) and other mechanical hysteresis errors that are inherent in traditional enclosed encoders.
