Absolute linear encoder RESOLUTE™ RELA30

opticalnon-contactIP64

What is RESOLUTE? RESOLUTE is a true absolute, fine pitch optical encoder system that has excellent dirt immunity, and an impressive specification that breaks new ground in position feedback. It is the world's first absolute encoder capable of 1 nm resolution up to 100 m/s. Ultra low SDE and jitter result in a linear encoder system that outperforms any other encoder in its class. What is RELA30 scale? RELA30 is a spar scale manufactured from ZeroMet, a low expansion nickel/iron alloy, featuring our 30 µm pitch absolute scale code. It is comparable to fine pitch glass scales and offers a total accuracy (including slope and linearity) better than ±1 µm up to 1 m length. ZeroMet has a coefficient of thermal expansion of 0.75 ±0.35 µm/m/°C at 20 °C. System designers can choose between specially formulated adhesive tape or mechanical clips to suit mounting requirements. Both mounting methods allow for independent thermal expansion to that of the substrate.
