Thomson linear actuators offer advantages over fluidpower cylinders

With the recently announced increase in maximum dynamic load from 10 kN to 16 kN for stroke lengths to 500 mm, and with static loads to 18 kN, Thomson’s Electrak® HD series linear actuators are now an even more compelling alternative to hydraulic and pneumatic cylinders for positioning tasks on heavy-duty machinery and equipment. Available in the UK, with full support from Heason Technology, the Electrak HD range covers six load-rated models with stroke lengths from 100 mm to 1 metre (in 50 mm increments). With 12 or 24 VDC operation, a wide choice of built-in control options include J1939 CANbus, open or closed loop positioning, analogue and digital position output, axis synchronisation and PLC compatibility. These combine with a comprehensive choice of mechanical interfacing options to make application integration and operation straightforward.

The Electrak HD series has a smaller footprint, requires much less maintenance and is a much cleaner solution than hydraulic or pneumatic cylinder alternatives. In addition, its superior controllability offers easier integration with modern computer controlled systems and more precise positioning control.

The actuators also offer a durability that will suit the harshest environments, with IP67 rating for static use and IP66 for dynamic positioning as standard. An IP69K version is available for the food industry and other automation tasks where frequent washdown is required. The Electrak HD series will operate at high loads in temperatures ranging from -40 to +85 °C. For maximum loads, a generous 25% duty cycle ensures operation for demanding high-throughput positioning tasks.

Safety is available via thermal and voltage or current load protection with end-of-stroke limit switches, manual (mechanical) override and integrated motor-brake for complete safeguarding.

The robust Electrak HD design is well proven in a wide range of applications in automotive, agricultural and construction equipment where the industry standard J1939 CANbus control network is well established. A high-efficiency ball screw system with parallel mounted motor and gear components are housed in a robust hard-coat anodised aluminium housing. Internally the motor and gear unit are housed in a zinc frame providing extra protection. The stainless steel anti-rotation extension tube is fully sealed inside the housing and a wide choice of mechanical interfacing options include rod-end and threaded adapters for straightforward mounting.

Heason Technology supplies and supports a wide range of linear motion components from Thomson Industries. Along with distribution partnerships with other leading motion equipment suppliers and with its in-house design and system integration capability, the West Sussex based motion specialist serves a diverse range of industries and research organisations with everything from individual motors, drives, controls and positioning mechanics to fully automated systems that include custom -designed mechanics and motion controls.
