RGH22 series readhead

Renishaw’s RG2 linear
encoder system is a noncontact optical encoder
designed for position
feedback solutions.
The system uses a common reflective
tape scale scanned by a readhead chosen
from a range of options offering industry
standard digital square wave or analogue
sinusoidal output signal formats.
Renishaw’s patented optical scheme is used
in all readhead series and gives proven
performance benefits together with high
tolerance to scale contamination.
The RGH22 range is suitable for use in a
broad range of applications, offering high
resolution and high speed with stability
and reliability.
A dual limit sensor option is also available
offering two dedicated signal outputs, left
and right end-of-axis travel indication.

RGH22 is an ideal feedback solution
wherever precision controlled movement
is required. The RGH22 readheads offer
the full set of RG2 features and integral
interpolation in a robust package, with an
integral set-up LED for quick and easy
installation.
Common applications include co-ordinate
measuring and layout machines, semiconductor/electronics manufacturing and
inspection, height gauges, electronics
assembly and test, linear motors, digital
image setters and a variety of custom linear
motion solutions.
