Digital-analogue position indicators positive drive, technopolymer CASE Glass-fibre reinforced polyamide based (PA) technopolymer, black colour, matte finish. Moulded-in spindle. BEZEL Technopolymer. Moulded over the window. WINDOW Transparent polyamide based (PA-T) technopolymer (practically unbreakable). Resistant to solvents, oils, greases and other chemical agents (avoid contact with alcohol during cleaning operations). DIAL Natural matte anodised aluminium. Clockwise or anti-clockwise graduation, black colour. READING Five-digits roller counter (four black rolls and one red roll) and one red pointer which turns on the graduated dial. The digit of the red roll shows the decimal values, while the pointer shows the hundredth. The display indicates the displacement of the mechanism controlled by the spindle from the start position (0). One complete turn of the machine spindle corresponds to a turn of the handwheel/knob and consequently to a turn of the red pointer. A turn of the red pointer corresponds to a determinate reading on the counter (see "reading on the counter after one revolution of the red pointer" in the table). IP PROTECTION The ultrasonic welding of the window to the case guarantees the complete sealing with IP 65 protection class, see table EN 60529 (on page A-18). FEATURES AND APPLICATIONS Digital-analogue positive drive indicators are suitable with spindles in any position. To choose the handwheel see the table "Handwheels/knobs - possible assembly with indicators" (on page 635).
