FOX Rotary limit switch
Rotary limit switch used to control and measure the movement of industrial machines by measuring the rotation angle and/or counting the number of revolutions of a shaft. Fox is used on wind turbines to control the position of the nacelle or the pitch angle of the blades
This combination does not exist.
It consists of a gear motor that transfers movement to the cams and the other movement detection devices through a primary input reduction stage (worm gear and helical toothed gear) and one or more secondary output stages (pairs of straight toothed gears). Accurate adjustment of cams by means of screws. Positive opening NC contacts for safety functions. Mechanical life of switches: up to 10 million operations. IP protection degree: Fox is classiied IP66, IP67 and IP69K. NEMA protection degree: Fox is classiied Type 4X*. Extreme temperature resistance: -40°C to +80°C. It features transmission and gear driving shafts made of stainless steel AISI 430F or AISI 303. worm gear transmission shaft rotating on ball bearings, self-lubricating technopolymer gears and driving bushes, technopolymer base and cover. All materials and components used are wear resistant and guarantee protection of the unit against water and dust.
