Non-contact linear absolute encoders – EXT

Non-contact open linear absolute encoders - EXT

Non-contact open linear encoder for high accuracy, high speed applications.

It consists of a compact reader head with all the electronics and optics integrated into a single body that may be mounted from the side or from the top.
It has an LED to help mounting it and includes a 1 or 3 meter cable with a connector, a 10 mm wide reflective stainless steel tape that is highly resistant to solvents on an adhesive or bolted aluminum guide.

Measuring lengths in millimeters:
Available from 140 mm to 3,040 mm in 100 mm (*) increments.
