Linear Encoder

04/01/2000

The RGH25-UHV linear encoder can withstand an extended 120°C bake-out process before being used in UHV chambers with pressures as low as 10-10 Torr. It is capable of speeds to 5m/sec, and combines with a self-adhesive, cut-to-length steel tape scale to provide resolution to 0.1 micron. The readhead measures 36 x 14.3 x 12.5 mm and weighs 22g. The readhead has a low rate of outgassing and a clean residual gas analysis. The encoder is available with either digital or analog outputs, and the open, non-contact design eliminates hysteresis and seal friction/wear.
