Electric linear actuator.

Thomson Industries has launched the Electrak LL electric linear actuator, a long-life, high-duty-cycle component designed to work in the harshest conditions and offer superior environmental protection. In addition to having improved functionality dedicated to high duty cycle applications, the Electrak LL comes standard with all the performance, reliability and durability features that have made Thomson an industry leader in linear actuators.

With increased UV resistance capabilities, a long-life ball screw and nut assembly, and a long-life manual override design, the Electrak LL actuator is built to last. “The Electrak LL actuator is designed to deliver long life in harsh conditions and utilizes an improved sensor design that offers an integrated, robust solution to our customers. This new actuator is designed to last up to 600 kilometers, which is more than 10 times longer than the standard actuator,” said Anders Karlsson, Product Line Specialist – Linear Actuators at Thomson.

The load-bearing design of the Electrak LL electric actuator features two bearings to handle bidirectional load, as well as a built-in, brushless motor and motor drive system. This system provides constant speed regardless of the load and delivers the safety functionalities of the Thomson Electronic Monitoring Package. Eliminating the need for standalone controls, these integrated features provide constant monitoring of critical parameters such as end-of-stroke, voltage, current and temperature.

The actuator can withstand temperatures from -40° to +85°C (-40° to +185°F), and is CE and RoHS compliant, making it easier for operators to interact with and control operations, and providing a better user experience in all environments. Its coated, painted and sealed housing is rated to IP69K (static) and IP66 (dynamic) standards, meaning it resists corrosion from UV radiation, water jets, high-temperature/high-pressure washdowns and other forces. 

Such high environmental resistance makes Electrak LL electric actuators ideal in outdoor applications such as pantographs, couplers, steps, access lifts and gravel bins. Standards and safety regulations for railway equipment can be very demanding and require rigorous testing to ensure compliance, and the Electrak LL was built to comply with railway standards EN 50155, EN 60077 and EN 45545.

Long-life actuators such as the Electrak LL are also valuable on the plant floor for high-duty cycle applications such as material handling and logistics operations. For example, automated guided vehicles (AGVs) and logistics trains often run 24/7, exposing their components to excessive wear and tear, however, the durability of these actuators extends replacement intervals significantly.
