The LA22 is an in-line actuator specially designed with a small overall dimension for
easy use in industrial, agricultural, and rehabilitation products.
Thanks to its small outer dimensions and linear design, the LA22 is well suited for
applications where installation space is limited, such as on wheelchairs.

The LA23 is a small and strong push actuator (up to 2500 N). The LA23 can be used
in various applications where size is important. The LA23 is e.g. ideal for adding tilt-
function to a desk, so the table top can tilt or for adjustment in handicap kitchens.
Some of the benefits the LA23 offers you are:
• Compact design
• High lifting force
• Exchangeable cables
Usage:
• Duty cycle: 10 %, 2 minutes continuous use followed by 18 minutes not in use
• Usage temperature: +5 °C - +40 °C normal operating temp.
-30 °C - +50 °C according to test conditions: ISO 7176-9
• Storage temperature: -45 °C to +70 °C (according to ISO 7176-9)
• Compatibility: DESKLINE Control boxes.
SLS must be ignored Up + Down in the CBD4, when configured for LA23 and in the CBD6S with old actuators.
• Approved according to EN60335-1 with CBD6S
• Flammability rate: Enclosure UL94-V0
• Cycles: The LA23 Life cycle test has been performed with a stabilised power supply (10 % duty cycle) on a 200 mm stroke
actuator at max. load at 5000 cycles

Warnings
• Do not sideload the actuator.
• Only use the actuator within specified working limits.
• When mounting the LA23 in the application ensure that the bolts can withstand the wear and that they are secured safely.
• If an actuator with stroke length below 50 mm is used, and the electrical end-stop switch fails, please be aware that the distance before reaching
the mechanical end- stop will be prolonged. The extra distance will be 50 mm minus actual stroke length.
I.e. If an actuator with 20 mm stroke length is used and the switch fails, it will travel an additional 30 mm before reaching the mechanical end-stop.
• Instruction concerning the turning of the piston rod eye
When mounting and taking into use, it is not permitted to make excessive turns of the piston rod eye. In cases where the eye is not positioned
correctly, it is permitted to first screw the eye down to its bottom position, at a maximum torque of 2 Nm (1), and thereafter a maximum half
turn outwards again (2).
