Glass-fibre reinforced polyamide based (PA) technopolymer, black colour, matte finish.
Technopolymer. Moulded over the 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).
Natural matte anodised aluminium.Clockwise (D) or anti-clockwise (S) graduation, black colour.
Black-oxide steel boss, H7 reamed blind hole, fitting to shaft by means of a supplied grub screw with hexagon socket and cup end UNI 5929-85.
Five-digits roller counter 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 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).
Ballrace rotation: maximum reading accuracy.
The ultrasonic welding of the window to the case guarantees the complete sealing with IP 67 protection class, see EN 60529 table
