Precision electric actuators offer longer life and up to 100 % duty cycle
Electrak ® LL series high performance electric actuators from Thomson Industries Inc . are aimed at applications where long maintenance-free working life and extended duty cycle lifting and moving tasks in challenging environments are prime requisites . Available with full support from Heason Technology , Thomson ’ s authorised UK distributor , the Electrak LL combines a high-efficiency brushless motor and drive with low friction ball screw and nut mechanics in a sealed IP66 rated housing that includes onboard control . An ideal standalone solution for gate and valve control , pick and place , logistics and materials handling and more , the durable actuator ’ s 24 V supply voltage and high efficiency makes it especially well-matched for mobile machinery applications in construction and agriculture as well as a compelling alternative for pneumatic or hydraulic cylinders on lift and load machinery . With a choice of stroke lengths from 100 to 500 mm , a full load up to 6 kN at 35 % duty cycle and 100 % duty cycle for task-dependant lower loads , the actuator has a travel life of 600 km .
The Electrak LL series ’ control card provides standalone end-to-end position control triggered by separate extend and retract inputs - or the stroke can be set and adjusted by externally located end of stroke limit switches that can be and configured to provide overtravel protection . The controller - which complies to the railway standards EN 50155 , EN 60077 and EN 4554 - delivers a constant speed regardless of the actual load and includes controlled braking for repeatable and protected operation for the actuator and its connected equipment . To further ensure safe and reliable use , overload protection includes current monitoring that isolates the supply if exceeded , replicating a

mechanical clutch . The controller further includes temperature monitoring with compensation in addition to voltage monitoring whilst a mechanical holding brake option prevents back-driving for vertical oriented positioning . The long-life ball-screw and nut assembly also features a load-dependant locking capability .
The LL series actuator is supplied in stroke lengths from 100 to 500 mm in increments of 50 mm . Dynamic load rated options of 4 or 6 kN are available with speeds set at 30 or 15 mm / sec respectively . With its 35 % duty cycle at full load , the actuator is estimated to have a 10 to 20 % higher duty performance rating than other comparable electric linear actuators . Heason Technology engineers can assist for detailed life vs . load calculations where up to 100 % duty cycle is possible .
Wide application flexibility is ensured with a comprehensive choice of front and rear mechanical interfacing options that include stainless steel pin , forked and threaded adapters . The Electrak LL is particularly robust and durable with a highly corrosion protected aluminium and polycarbonate housing which is washdown-compatible and includes UV-resistant surface treatment . Specifications , options and accessories are covered in a 16-page brochure , available on request from Heason Technology .
With its own in-house design and system integration capability Heason Technology has represented Thomson for several years and supports other globally leading motion control equipment suppliers . The West Sussex based motion specialist offers comprehensive sales and service from single components such as stepper and servo motors , intelligent drives , motion controls and positioning mechanics to fully automated systems that include bespoke mechanics complete with drive electronics and automation control software .
