Actuator LA31
Data sheet

LINAK.COM/DESKLINE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 verycompact. The LA31 is designed for use together with theDESKLINE 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 backfixture• 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

LINAK.COM/DESKLINE

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

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.
