Model 260 - incremental encoder
F e at u r e s
Low Profile 1.19"
Up to 12 Pole Commutation
Thru-Bore and Hollow Bore (Blind) Styles
Simple, Innovative Flexible Mounting System
Incorporates Opto-ASIC Technology
CE Marking Available
With a bore up to 0.625" and a low profile, the Model 260 Accu-Coder™ is the perfect
solution for many machine and motor applications. Available in both hollow bore and
a complete thru-bore, the Model 260 uses EPC’s innovative anti-backlash mounting
system, allowing simple, reliable, and precise encoder attachment. Unlike traditional
kit or modular encoder designs, its integral bearing set provides stable and consistent
operation without concerns for axial or radial shaft runout. For brushless servo motor
applications, the Model 260 can be specified with three 120° electrical phase tracks
to provide up to 12 pole commutation feedback. The optional extended temperature
capability allows servo motors to operate at higher power outputs and duty cycles.
And of course, the Model 260 uses EPC's pioneering Opto-ASIC design, so you'll always
get a clean, reliable signal.
