Base and case
High-resistance polyamide based (PA) technopolymer.
Case in the following colours:
Transparent polyamide based (PA-T) technopolymer, moulded over the case and with a perfect seal (avoid contact with alcohol during cleaning operations).
It indicates the displacement of the mechanism controlled by the spindle from the start position (0). Four-digit roller counter. The digits of red rolls show the decimal values. An additional graduated scale next to the last decimal digit offers further accuracy of reading. The display can be in different positions (see "Example of description for ordering").
O-ring front sealing in NBR synthetic rubber, between the case and the boss.
Foam polyethylene, supplied.
Bushing with Ø 14 mm H7 reamed hole, fitting to shaft by means of a supplied grub screw with hexagon socket and cup end, included in the supply.
Direction of rotation
Features and applications
Direct drive digital position indicators can be assembled on passing through spindles in any position to give direct reading of the positioning of a machine component. They are suitable also for motor driven applications (see "Example of description for ordering").
Ergonomy and design
Compact roller counter, ergonomically designed digits for rapid reading. The readability of the counter is increased by the magnifying window.
Special executions on request
Completely sealed digital position indicators with IP 67 protection class, see EN 60529 table obtained by means of a brass bushing with double seal ring inside the rear cavity of the base.
LB - locking device
The DD51-LB position indicators are designed to lock the spindle on which they are mounted to avoid the risk of accidental adjustment alterations due to vibrations. To lock or unlock the spindle rotation, simply move the lever, in pos. A equivalent to unlocked spindle, in pos. B equivalent to locked spindle.
Following repeated locking cycles, the special device is highly wear resistant and functions perfectly over time.
To order the indicator with spindle locking add the –LB index after the code and description (e.g. CE.84101-LB DD51-AN-00.50-D-C3-LB).
