The Fuji Electric AR30 series includes a selection of 30-mm push buttons, nonilluminated as well as illuminated models, with flush round heads, extended round heads and mushroom-style heads. Other Fuji 30-mm pilot devices include emergency stop push buttons, selector switches, pilot lights, joysticks and buzzers. AR30 pilot devices can be mounted on panels from 1 to 6 mm thick in panel cutouts of 30.5 mm in diameter. They provide quick snap-on replacement of contact blocks and can be wired in horizontal and vertical directions, making wiring in narrow spaces easier. The devices include a terminal cover for added safety; available oil- and dust-proof operator modules are IP65-rated.
