Linear and Rotary Encoders

RGH22 Encoder System
Linear Encoder

Compact and robust readhead with internal interpolation offers industry standard digital and analogue outputs
Non-contact design offers high speed, reliable operation with zero friction and zero wear
Integral set-up LED enables easy readhead installation
Filtering optics guarantee excellent signal stability in conditions unsuitable for most open, optical encoders
The reference mark provides a repeatable home position whilst limits offer end of axis travel indication

Operating and Electrical Specification

Power Supply	5 V ± 5% 120 mA (typical), 200 mA RGH22Y, S, H NOTE: For digital outputs, current consumption figures refer to unterminated readheads. A further 25 mA per channel pair (eg A+, A-) will be drawn when terminated with 120 Ω. Renishaw encoder systems must be powered from a 5 V dc supply complying with the requirements for SELV of standard EN (IEC) 60950. Ripple 200 mVpp @ frequency up to 500 kHz maximum.
