Linear and Rotary Encoders

RGH41 Encoder System
Linear Encoder

Index mark at the center or end of the glass scale(linear)
Compact and robust readhead with internal interpolation offers industry standard digital and analogue outputs
High speed, reliable operation with zero friction and zero wear
40 µm scale pitch offers generous readhead set-up tolerances
Integral set-up LED simplifies set up
Patented 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), 175 mA (RGH41N, W, Y, H) NOTE: For digital outputs, current consumption figures refer to unterminated readheads/ interfaces. 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 maximum @ frequency up to 500 kHz maximum
