Rotary limit switch Rotary limit switch used to control and measure the movement of industrial machines. Its compact size makes it suitable for use in narrow spaces. • It consists of a gear motor that transfers movement to the cams 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: 1 million operations. • IP protection degree: Base is classified IP42, IP65 or IP66, IP67 and IP69K. • NEMA protection degree: Base IP66, IP67 and IP69K is classified Type 3. • Extreme temperature resistance: -40°C to +80°C. • It features stainless steel AISI 430F transmission and gear driving shafts, self-lubricating technopolymer gears and driving bushes, technopolymer base and cover. • Sintered bronze bushes are moulded into the base of the limit switch to optimize shaft rotation and prevent rubbing with plastic material. • All materials and components used are wear resistant and guarantee protection of the unit against water and dust. • Revolution ratios from 1:15 to 1:1500, achieved by combining different secondary output stages. • Snap action switches with 1NO+1NC contacts. • It can be equipped with a cam set with maximum 6 switches. • Dedicated cable clamps or connectors. • Available with anti-moisture plug fitted to the base by means of a lock nut, to improve transpiration for the limit switch while maintaining protection against water. • Available with flanges, pinion gears and couplings. • Available with direct control switches to enable direct action on the motor.
