Case and base

High-resistance polyamide based (PA) technopolymer. The base is ultrasonically welded to give more strength and avoid dust penetration. Resistant to solvents, oils, greases and other chemical agents.

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 bushing.

Rear gasket

Polyurethan (included in the supply).

Colour

- Execution AR: RAL 2004 orange, glossy finish.
- Execution GR: RAL 7035 grey, glossy finish.
On request and for a quantity of at least 10 pieces, it is available in anthracite colour (execution NR).
Base in black colour.

Assembly

Black-oxide steel bushing with Ø 10 mm H7 reamed hole, fitting to shaft by means of a grub screw with hexagon socket and cup end, according to UNI 5929-85, supplied assembled.

Reading

Three-digit roller counter (two black rolls and one red roll or one black rolls and two red rolls, on request three black rolls). The digits of red rolls show the decimal values. The display indicates the distance covered by the mechanism controlled by the spindle from the start position (0).
Display reading is available in different positions (see below "Table of the possible combinations").

Direction of rotation

- D: clockwise. Increasing values with clockwise rotation of the bushing.
- S: anti-clockwise. Increasing values with anti-clockwise rotation of the bushing.

Weight

21 grams.

Special executions on request (For sufficient quantities)

- AISI 303 stainless steel bushings.
- Completely sealed digital position indicators with IP 67 protection class, according to IEC 529 table.
The complete sealing is guaranteed by the ultrasonic welding between the case and the base, by the magnifying window moulded over the case, by the O-ring front sealing inside the case and by a brass bushing with double seal ring inside the rear cavity of the base.
- Special readings after one revolution.
- Special reduction sleeves.
- Case in different colours.

Features and applications

Direct drive digital position indicators are suitable on passing through spindles in any position to give direct reading of the positioning of a machine component. They are designed also for motor driven applications (see below "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.

Assembly instructions

1. Drill a Ø 6 mm by 10 mm hole in the body of the machine with a 18 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 bushing to the spindle by tightening the grub screw with hexagon socket and cup end, according to UNI 5929-85.
