DD51 / Digital Position Indicators, Direct Drive, 4-Digit Counter, Technopolymer
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 “Table of the possible combinations").
Ergonomy and Design
Compact roller counter, ergonomically designed digits for rapid reading. The readability of the counter is increased by the magnifying window.
Material
Base and Case
High-resistance polyamide based (PA) technopolymer.
Black base.
Case in the following colours:
- C2: RAL 2004 orange, glossy finish.
- C3: RAL 7035 grey, glossy finish.
- C1: RAL 7021 grey-black, glossy finish.
The ultrasonic welding between the base and the case prevents separation and avoids dust penetration.

Window
Transparent polyamide based (PA-T) technopolymer, moulded over the case and with a perfect seal. Resistant to solvents, oils, greases and other chemical agents (avoid contact with alcohol during cleaning operations).
Internal Gasket
O-ring front sealing in NBR synthetic rubber, between the case and the boss.
Rear Gasket
Foam polyethylene, supplied.
Display
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 "Table of the possible combinations").
- AN: inclined display, counter in upper position.
- AR: inclined display, counter in lower position.
- FN: front display, counter in upper position.
- FR: front display, counter in lower position.

Dimensional Drawing
Example of Description for Ordering
*The maximum rotation speed (rpm) of the spindle reported in the table corresponds to a maximum rotation of 25000 units of the last roll on the right of the counter.
Rotational speed tests have been performed in our laboratory under standard operating conditions.
Small misalignments (not compromising the correct reading) of counter digits can occur due to high tolerances between gear teeth, designed to prevent damage from sudden acceleration or stop.
Assembly Instructions
1. Drill a Ø 6 mm by 10 mm hole in the body of the machine with a 22 mm centre distance from the spindle to fit the rear referring pin.
2. Set the spindle to the start or referring position.
3. Fit the indicator with the zeroed roller counter onto the spindle and make sure that the referring pin fit the hole.
4. Clamp the boss to the spindle by tightening the grub screw with hexagon socket and cup end, according to UNI 5929-85.

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).
