Options:

• LA31 Basic version CARELINE^® (no slot in piston rod eye)

• Flexible back fixture

• Reed switch (8 pulses per spindle revolution) for exact position- ing of memory control and compatibility with CB9P

• Fast motor

• Mechanical splines (the actuator can only push)

• Jack plug for use with other control boxes than CB9

• Protection class IP 66. Not for wash tunnels!

• Quick release on LA31 (different types of release handle)

The LA31 actuator is a very quiet and powerful actuator designed for a variety of applications such as furniture, care or hospital beds. The standard LA31 actuator is available for both the HOMELINE^®, CARELINE^® and DESKLINE^® product range.

Due to its high capacity, design and protection class up to IP 66 the CARELINE^®actuator is ideal for the care sector e.g. for beds. The CARELINE^®LA31 actuator is available as a standard or a Basic version. The standard LA31 actuator features known parts such as piston rod eye with slot. The Basic version is a special cost optimised version, which is compatible with the CB9 Basic control box. The LA31 Basic actuator is also available in a special version with a fast motor.

Back fi xtures:

Piston Rod Eyes:

The LA31 actuator must not be exposed to more than 4000 N in pull. In applications were misalignments may occur the normal back fixture can take max. 1500 N in pull where as the flexible back fixture can take up to 4000 N in pull.

If an LA31 is used in an application where there are repeated dynamic pulling movements in the area 2000 - 4000N, then it is necessary to contact the Technical Support department in order to make a correct specification of the actuator.

Comments to table:

* LINAK control boxes are designed so that they will short-circuit the motor terminals (poles) of the actuator(s), when the actuator(s) are not running. This solution gives the actuator(s) a higher self-locking ability. If the actuator(s) are not connected to a LINAK control box, the terminals of the motor must be short-circuited to achieve the self-locking ability of the actuator.

** When the load in push is above 4000 N (max. 6000 N), the max. stroke length is 250 mm.
