Rotary limit switch Rotary limit switch used to control and measure the movement of industrial machines by reading 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. • 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 classified IP66, IP67 and IP69K. • NEMA protection degree: Fox is classified 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. • Revolution ratios from 1:3 to 1:2870, achieved by combining different secondary output stages. • Snap action switches with 1NO+1NC contacts or slow action switches with 1NC contact. • It can be equipped with a cam set (with up to 5 switches) and potentiometers, encoders, Yankee absolute encoders. • 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. • Plates with universal adapter to replace existing systems. The data and the products illustrated in this brochure may be modified without notice. Under no circumstances can their description have a contractual value. CERTIFICATIONS • CE marking, cULus* marking and EAC certification. • Fox is available, upon request, with the SIL1 certification (Safety Integrity Level 1), according to Standard IEC 61508. • Complying with accident prevention regulation BGV C 1 (only for Germany). • HALT TEST (Highly Accelerated Life Test) passed, simulating conditions largely exceeding standard operating conditions.
