Linear and Rotary Encoders

RGH24 Encoder System
Linear Encoder

Super-compact 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 the limit offers end of axis travel indication.
Available with many connector options including a 10-way JST connector for simple integration

Operating and Electrical Specification

Power Supply	5 V± 5% 120 mA Ripple 200 mVpp maximum @ frequency up to 500 kHz maximum 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. For analogue type B readheads, a further 20 mA 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.
