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 make it especially well-matched for mobile machinery applications in construction and agriculture as well as a compelling alternative for pneumatic or hydraulic cylinders on the 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 a 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 configured to provide overtravel protection. The controller – which complies with 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.
