Explosion proof rotary limit switch. Rugged and reliable, Limitex AG is used to control the movement of industrial machinery in potentially explosive areas.

Features - It consists of a gear motor that transfers movement 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: Limitex AG is classified IP66. - Extreme temperature resistance: -40°C to +60°C. - It features rugged external enclosure made of G20 cast iron, stainless steel transmission and gear driving shafts, 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 1:15 to 1:499, achieved by combining different secondary output stages. - Snap action switches with 1NO+1NC change-over contacts. - It can be equipped with a cam set with 2-3-4 switches. - Available with flange for direct coupling to the motor. - Available with direct control switches to enable direct action on the motor.

Cerification - CE marking. - Atex certification EN 60079-0:2009, EN 60079-1:2007, EN 60079-31:2009. - Conformity to Standards IECEx IEC 60079-0:2011, IEC 60079-1:2007-04 and IEC 60079-31:2008.
