Slim type digital indicator with low price. Large LCD and simple key operation. After the initial origin setting, the ID-U no longer needs absolute positioning over the entire battery life the origin is remembered even after power-off. Ideal for installation into measuring devices because of it’s compact design and long battery life. Employing the absolute linear encoder, the ID-U always displays the spindle "absolute position" from the origin at power-on. Also unlimited response speed eliminates over-speed errors. Flat back type only no option for backs. SPC data output.
