Rotary Connectors / Round Flange

[ ! ] Unless otherwise specified, the dimension tolerance conforms to JIS B 0405 Class m. However, chamfer tolerances are excluded.
[!] Structure with inner stopper prevents 360° rotation to prevent wiring from being twisted. (Rotates 350 degrees.)
[ ! ] Avoid giving excessive impact to the internal stopper when rotating, otherwise, it may cause damages.
