Optical Circle Encoder Read Head Support Digital Output And Analog
Output
The HXC grating system is known in the industry for their ease of installation.
The grid ruler is available in a variety of lengths, and the
special design of self-adhesive on the back enables the
installation without drilling screws, thus saving time and cost.
All reading heads and interfaces are monitored by patented LED
installation status indicators, increasing installation speed and
eliminating the need for oscilloscopes and other complicated
installation monitoring.
