Absolute linear encoder EVOLUTE™ RTLA50

opticalnon-contactIP64

What is EVOLUTE? Based on Renishaw's industry-proven absolute technology, the EVOLUTE series is a true-absolute non-contact optical encoder with a 50 µm scale period, bringing superb installation tolerances and greater dirt immunity for applications that demand not only the highest operational integrity, but where fast installation is critical. Resolutions down to 50 nm along with low SDE and jitter from cutting edge optical design and high-speed signal processing give the EVOLUTE encoder the targeted performance to meet the needs of the most demanding OEM applications. What is RTLA50 scale? RTLA50 incorporates the same stainless steel tape scale as RTLA, but this time with a 50 µm pitch version of our absolute scale code. It is accurate to ±10 µm/m and available in lengths up to 10.02 metres. Two mounting options are available, both of which allow independent scale thermal expansion and the convenience of tape scale. RTLA50 can be used with the revolutionary FASTRACK™ scale carrier system. This system allows a track to be laid quickly and easily with no need for fixing holes. A sacrificial spacer is removed and the tape scale is then fed into the track.
