Description
Data sheet L-9517-9493-01-A
RH200 encoder system The RH200 readhead works with 20 µm reflective tape scale, has unique filtering optics, set-up LED, and offers high speed performance. The RH200 offers generous set-up tolerances and maintains good contamination immunity.
• Non-contact open optical system • Large installation tolerances • Maximum speed 5 m/s • Reference mark or limit switch capability • Integral set-up LED • Uses Renishaw RH200 self-adhesive scale
