Additional information

Accessories on request (to be ordered separately)

RB50: black-oxide steel reduction sleeves (see table).

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.<BR>2. Set the spindle to the start or referring position.<BR>3. Fit the indicator with the zeroed roller counter onto the spindle and make sure that the referring pin fit the hole.<BR>4. Clamp the bushing to the spindle by tightening the grub screw with hexagon socket and cup end, according to UNI 5929-85.

Base and case

High-resistance polyamide based (PA) technopolymer. Resistant to solvents, oils, greases and other chemical agents.<BR>Black base.<BR>Case in the following colours:<BR>- <STRONG>C2</STRONG>: RAL 2004 orange, glossy finish.<BR>-<STRONG> C3</STRONG>: RAL 7035 grey, glossy finish.<BR>On request and for a quantity of at least 10 pieces, it is available in RAL 7021 (C1) grey-black.<BR>The ultrasonically welding between the base and the case prevents separation and avoids dust penetration.

Direction of rotation

– <STRONG>D</STRONG>: clockwise. Increasing values with clockwise rotation of the bushing.<BR>- <STRONG>S</STRONG>: anti-clockwise. Increasing values with anti-clockwise rotation of the bushing.

Display

It indicates the displacement of the mechanism controlled by the spindle from the start position (0).<BR>Three-digit roller counter (two black rolls and one red roll or one black roll and two red rolls, three black rolls on request). The digits of red rolls show the decimal values. <BR>The display can be in different positions (see "Guide to the choice of standard combinations").<BR>- <STRONG>AN</STRONG>: inclined display, counter in upper position.<BR>- <STRONG>AR</STRONG>: inclined display, counter in lower position.<BR>- <STRONG>FN</STRONG>: front display, counter in upper position.<BR>- <STRONG>FR</STRONG>: front display, counter in lower position.

Ergonomy and design

Compact roller counter, ergonomically designed digits for rapid reading. The readability of the counter is increased by the magnifying window.

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 below "Guide to the choice of standard combinations").

Internal gasket

O-ring front sealing in NBR synthetic rubber, between the case and the bushing.

Rear gasket

Foam polyethylene, supplied.

Special executions on request

– Special readings after one revolution.<BR>- Case in different colours.<BR>- Completely sealed digital position indicators with IP 67 protection class, see IEC 529 table, obtained by means of a brass bushing with double seal ring inside the rear cavity of the base.

Standard execution

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

Weight

21 grams.

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).
