New self-guided optical linear encoder with integrated bearings. Mainly intended, although not only, for press brakes
and shears. The linear encoder especially designed with a resolution of up to 1 μm, with a user-selectable reference position and with cable exit at either end of the reader head for a more versatile machine design.
The robust design, the mentioned characteristics together with both types of couplings (rod and flexible) offer the perfect solution to manufacturers of machines, forming equipment and cutting with the best quality-price ratio on the market.
