Linea­ris CL Ex 1

Elec­tro-mecha­ni­cal dam­per actua­tor for Ex-Zone 1

The CL series offers clas­sic dri­ve tech­no­lo­gy with motor/gear com­bi­na­ti­on and cam mecha­nism in a clas­sic design. Three series up to 300 Nm in com­bi­na­ti­on with various actua­ting times open up a wide ran­ge of app­li­ca­ti­ons for a wide varie­ty of indus­tri­al tasks. Of cour­se, the CL series offers not only a robust metal housing, but also all com­mer­ci­al­ly avail­ab­le opti­ons, from the addi­tio­nal limit switch to the posi­tio­ner with load cut-off. Three cable ent­ries M20 x 1.5 allow easy wiring even in the case of high-cross-sec­tion leads. The CL series is also avail­ab­le in vol­ta­ges of 230 V, 115 V, 24 V AC or 24 V DC.

A stain­less steel split spind­le with a dry­s­pin® spind­le nut ensu­res reli­able and main­ten­an­ce-free ope­ra­ti­on. Due to the high gra­di­ent, the requi­red engi­ne speed is signi­fi­cant­ly redu­ced in com­pa­ri­son to the clas­sic design, so that the engi­nes run much smoot­her and quie­ter. This con­si­der­a­b­ly increa­ses the ser­vice life of the motors. Ins­tead of the com­mer­ci­al­ly avail­ab­le cas­tings, Linea­ris CL uses ano­di­sed alu­mi­num machined parts, which are signi­fi­cant­ly more robust at low weight. The Linea­ris has been deve­lo­ped by prac­ti­tio­ners. Long holes in the bra­ckets allow easy assem­bly even by only one mecha­nic. Dirt depo­sits are pre­ven­ted by the spind­le in the dry run so that lar­ge and expen­si­ve bel­lows designs are no lon­ger requi­red. The syn­chro­nous motors used in the dri­ve head ope­ra­te with a pure­ly fre­quen­cy-depen­dent posi­tio­ning time and thus ensu­re pre­ci­se con­trol. A robust pow­der-coated housing reli­ab­ly pro­tec­ts dri­ve tech­no­lo­gy even in harsh indus­tri­al envi­ron­ments. Despi­te the com­pact dimen­si­ons of the dri­ve head, the Linea­ris CL allows all stan­dard opti­ons, inclu­ding emer­gen­cy ope­ra­ti­on in case of power fail­u­re.

The Linea­ris lift unit is also desi­gned to meet the requi­re­ments of the ATEX direc­tives so that the com­bi­na­ti­on of the line­ar unit and the zone 1 dri­ve is a reli­able unit.

The Linea­ris CL is avail­ab­le in stan­dard stro­ke lengths of 150 and 300 mm for actua­tors up to 5000 N.

Other stro­ke lengths are also avail­ab­le on request.

    High-helix: Hig­her life span and effi­ci­en­cy

    The dry­s­pin® tech­no­lo­gy is based on wear-resi­si­stant igus® high per­for­mance poly­mers, spe­ci­al­ly desi­gned for screw dri­ves, dry­s­pin® offers a hig­her life span and effi cien­cy to high-heli­xes by their cha­rac­te­ris­tics and geo­me­tries, spe­ci­al­ly matched to the nut and lead screw. By their free­dom from lub­ri­ca­ti­on, dry­s­pin® screw dri­ves are sui­ta­ble for usa­ge in rough indus­tri­al just as in clean and hygie­nic envi­ron­ments (e.g. labo­ra­to­ry auto­ma­ti­on).
