TOPRotary limit switch Rotary limit switch used to control and measure the movement of industrial machines or the position of the nacelle or pitch angle of wind turbines. Salt mist resistant and rich in options, Top is designed to meet the most demanding reguirements. 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: Top is classified IP66, IP67 and IP69K. • NEMA protection degree: Top is classified Type 4X*. • Extreme temperature resistance: -40°C to +80°C. • Salt mist resistant. • It features base and cover made of electrostatic varnished die-cast aluminum, transmission and gear driving shafts made of stainless steel AISI 303, worm gear transmission shaft rotating on ball bearings, self-lubricating technopolymer gears and driving bushes. • All materials and components used are wear resistant and guarantee protection of the unit against water and dust. OPTIONS • Revolution ratios from 1:1 to 1:8100, achieved by combining different secondary output stages. • Each of the three outputs can be set to a different revolution ratio to enable diversified control of the machine when special requirements need to be met. • Snap action switches with 1NO+1NC contacts or slow action switches with 1 NC contact. • It can be equipped with 3 cam sets (with up to 15 switches), potentiometers and encoders (alone or on top of cam sets with up to 2 switches), Egon 36-AL absolute encoders (alone or on top of cam sets with up to 2 switches) and Yankee absolute encoders (on top of cam sets with up to 4 switches). • XL version featuring cover rise available with 3 cam sets (with up to 18 switches), potentiometers and encoders (alone or on top of cam sets with up to 5 switches), Egon 36-AL absolute encoders (alone or on top of cam sets with up to 4 switches) and Yankee absolute encoders (on top of cam ° sets with up to 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. | • Plates with universal adapter to replace existing systems. £ CERTIFICATIONS c CO a> =3 =3 o • CE marking, cULus* marking and EAC certification. • Top 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). = o "IT l1 fS “D o >_ -o ^ Use the online configurator (https://configuratore.terworld.com) or fill in the ‘request form' for accurate product configuration.
