Panasonic fiber options/accessories include lens, reflector, reflective tape, fiber cutter, attachment, mounting bracket, & slit mask. Using the arm which enables adjustment in the horizontal direction, sensing can also be done from above an assembly line. The protective tube, made of noncorrosive stainless steel, protects the inner fiber cable from any external forces. Do not bend the sleeve part of any side-view type fiber or ultra-small diameter head type fiber. The joint internal ferrule (MS-FX-YF) is available as a spare part. A distorted ferrule may result in leakage.
