Specifications:
DC Power: 5VDC @ 120mA
Output Signal: Square wave differential line driver to EIA RS422 (except limit switch Q
and external set–up signal X).
Model Resolution Speed (m per second) Edge Separation (µ seconds)
RGH22D – 5µm resolution 5 0.5
RGH22X – 1µm resolution 3 0.15
RGH22Z – 0.5µm resolution 1.5 0.15
RGH22Y – 0.1µm resolution 0.3 0.1
The non–contact optical encoder is designed for position feedback solutions. The
encoder system uses a reflective tape scale that is scanned by a read head. The RGH22
offers high resolution and high speed with stability and reliability.
