Linear Encoders

Optical Encoders deliver up to 50 nm resolution.

Models RG2 (20 Â-µm) and RG4 (40 µm) are open, non-contact linear encoders that combine cut-and-tape steel scale with side-lit filtering optics, offering immunity to dirt, dust, and contamination. Along with choice of clocked outputs to promote controller compatibility, products feature overspeed as well as low-signal alarms. Other features include RGE and RGB interfaces and...
