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.
Features - 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.
Options - Revolution ratios from 1:3 to 1:2870. achieved by combining different secondary output stages. - Snap action switches with 1NO+1NC change-over 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 whilst maintaining protection against water. - Available with flanges, pinions and couplings. - Plates with universal adapter to replace existing systems.>/p>
Certifications - CE marking, cULus* marking and EAC certification. - Fox is available, upon request, with the SIL1 certification (Safety Integrity Level 1), according to Standard IEC61508. - Complies with accident prevention regulation BGV C 1 (only for Germany). - HALT TEST (Highly Accelerated Life Test) passed. simulating conditions largely exceeding standard operating conditions.
