LA3 is a powerful actuator yet small enough to fit to most applications. The actuator can be supplied with options such as built-in potentiometer for servo operation or an extra powerful motor for increased speed and strength (S-motor). In addition to industrial and agricultural applications, the actuator is also ideal for positioning satellite dishes. The system actuator LA3L (option) can be combined with LINAK control boxes and it is perfet for a variety of furniture applications.

Accessories for LA3: Control card The CS16 electronic limit switch is connected between the LINAK actuator and a non-linak power supply, where it cuts out the current to the actuator in end position or if an obstacle is encountered. The PCB contains a variable current limit setting and is available in different versions, depending on which actuator it is to be used with. Above mentioned guarantees the maintenance of the long life of the LINAK actuator. The CS16 is an important component which ensures a long life for the actuator. Limit Switch There are two types of LINAK limit switches, for LA3, LS and LSD. The LSD type controls the stroke length of the actuator between two fixed end positions by cutting off the current to the motor. The LS type gives signal in two fixed end positions, but requires a control unit to stop the actuator when the micro switches are activated. Bellows Give a better protection and therefore give a higher liftetime of the actuator Protects inner tube against dust and dirt Can be used for actuators: LA3 Does not change the IP rating Available in black colour Ask for special folder Please contact your nearest LINAK dealer for further details or read more on www.linak.com.
