ACTUATOR LA27 - Linak

PRODUCT DATA SHEET
ACTUATOR
LA27
Features:
• 24V DC permanent magnet motor.
• Thrust up to 8000N (in a push application)
• Thrust up to 4000N (in a pull application)
• Elegant and compact design with small
installation dimensions
• Protection class: IPX4, IPX6
• Colour: Dark grey or light grey
• Built-in end stop switches (not adjustable)
• Possible to mount on control box CB6 with a
special mounting clip (article no. 009271002 is
delivered with CB6 )
• Scratch and wear resistent powder painted
steel inner tube.
• Brake ensures the self-locking
ability in either push or pull
directions.There will always
be a reduction of the selflock
characteristic when the
actuator is run in the opposite direction to the
brake direction
• Thrust up to 3500N in push with Quick Release
• LA27 with Quick Release can have ratchet spline
it can only pull with max.100N (anti-squeeze).
• LA27 with QR can be combined with std. spline
function, it can only push.
• Compatible with CB9C (only with the versions AC,
AD, AE or AH), CB6, CB6S OBL/OBF, CB6S OBM,
CB16 OBL/OBF, CB20)
• Noise level 50dB (A), actuator not loaded
Usage:
• Duty cycle: 2/18; 2 minutes continuous use
followed by 18 minutes not in use
• Duty cycle: Max 5% or 1 min. continuous use
followed by 19 minutes not in use - with 8000N
version.
• Lifetime limited to only 3000 cycles according to
EN1970 - with 8000N version
• Ambient temperature: +5 o to +40 o C (the
actuator must also be at this temp.)
• LA27 is approved according to EN 60601-1 /
UL60601-1
The LA27 actuator is a powerful actuator designed
for applications such as furniture and home
carebeds.
The LA27 actuator is developed for both push
and pull applications and has a very robust
construction because of the ultrasonic welded
plastic housing.
The LA27 actuator is equipped with a plug for
connection of exchangeable cable with minifit
connector. This gives the possibility to order
standard actuators and combine them with
different cable lengths.
Because of the built-in signal switch and the
special plug in the LA27 it is only compatible with
control box CB6.
The LA27 actuator has a small standard
programme where only a few standard lengths
and built-in dimensions are available.

Usage:
NOTE: re. LA27 with 6.000N specification (274x3xxx1xxx0xZ; Z = A or B i.e with Bouverat worm axle*) for
OpenBus:
I.e. to use such combination a preceding test MUST be carried out.
This combination reduces the self-lock ability because of lower friction from the Bouverat worm which has a
rolled axle. The Bouverat worm is however needed because of the OpenBus output power.
The alternative is a milled worm axle, but this may mean reduced lifetime of the worm.
The problem related to an application:
The self-lock ability may be reduced in cases where the load curve is 6.000N in both minimum and maximum
stroke length - see (A). Further such load distribution may reduce the lifetime of actuator.
A reduced load curve e.g. as in illustration (B) may also result in reduced self-lock, however it may have less
impact on the lifetime of the actuator.
Required test to ensure compatibility:
(only needed for LA27 with 6.000N for OpenBus (274x3xxx1xxx0xZ; Z = A or B))
The purpose is:
• to observe the actual load curve distribution (comparison to above curves). If load curve results are better
than the above you can proceed. If in doubt about evaluating the load curves please contact your
LINAK A/S sales engineer.
• to observe the self-lock ability in the actual application. In fact the application design may support the
self-lock ability in such a way so that LA27 no longer sinks. Normally the actuator is not allowed to sink,
however it is the customer who decides if it can be accepted (depends on the application type).
• a lifetime test MUST be carried out by the LINAK Subsidiary or be documented by the customer to ensure
that mutual expectations are met.
I.e. All LA27 with 6.000 N load specification (all 4 mm spindle types) MUST be tested as described before they
can be accepted for running production. However samples for test are available.
FOOTNOTE:
* REMARK: Z as type ‘0’ does not use the Bouverat worm. However type ‘0’ is NOT compatible with the
transformer used for OpenBus CB’s
