LA31 The LA31 actuator is a very quiet and powerful linear actuator desigend for a variety of desk applications ranging from kitchen applications to industrial table purposes. The LA31 actuator fits into very narrow places, as it is very compact. The LA31 is designed for use together with the DESKLINE control boxes CBD4, CBD5 and CBD6 and it either can work as a single actuator or used in parallel drive. Features: • 12 V DC motor • Thrust up to 3500 N • Small built-in dimension with short piston rod eye and back fixture • High-strength plastic housing protects motor and gears • Colour: black • Straight cable with mini fit connector (0.25 m) • Built-in limit switches (not adjustable) • Scratch and wear-resistant powder painting on outer tube ø30 mm • Strong wear and corrosion resistant stainless steel inner tube • Brake which increases the self-locking to 2500 N for LA31 with 6 mm pitch • Noise level 48dB(A); measuring method DS/EN ISO 3746, actuator not loaded • Hall sensors (24 pulses per spindle revolution) for exact positioning of memory control and compatibility with CBD Options: • Safety nut for push applications Usage: • Single or parallel drive • Duty cycle: Max. 10 % or 2 minutes continuous use followed by 19 minutes not in use • Ambient temperature +5°C to +40°C • Compatible with DESKLINE® CBD4, CBD5 or CBD6 control boxes and DESKLINE® controls • Approved according to EN 60335-1 • Approved according to UL 962 • Storage and transport temperature: -20 °C to + 70 °C LINAK.COM/DESKLINE

Dimensions of LA31 in combination with CBD4: LA31 in combination with CBD4 needs to be initialized at starting up. The stroke length is therefore reduced and the installation dimension increased. The values are the same for the different spindle types. Reduction of stroke length 3 mm Increase of installation dimensions 2.5 mm Technical specifications: Spindle type Standard 12 V motor with CBD4 311XXX-X0XXXXXX 317XXX-X1XXXXXX 313XXX-X1XXXXXX 316XXX-X1XXXXXX Spindle pitch [mm] 3 6 9 12 Max. load [N] 3500 2500 1500 1000 Typically Speed [mm/s] unloaded loaded 5 5 10 10 15 15 20 20 Self lock [N] 3500 2500 1500 1000 CBD4 with a 200 W transformer: • Up to 2 x LA31 can be connected.
