Thomson introduces compact electromechanical linear actuators

Hkan Persson of Thomson says: "Traditionally, motion control users looking for a higher load handling system are using hydraulic actuators. However, these actuators are costly to maintain and use a lot of space. With our new compact Electrak MD, designers can now achieve high precision and greater flexibility while reducing costs." The new Electrak MD also comes with onboard intelligence, which, according to Thomson, enhances the overall performance and eliminates space consumption by keeping any external equipment such as encoders and switches within the actuator housing itself. As with its predecessor, (the Electrak HD), this functionality provides a simpler method of control and communication, helping to minimise operating costs as well as simplifying setup and installation.

In addition to the above benefits, the Electrak MD also features extensive automation and maintenance enablers such as feedback on position, J1939 CAN bus communication, low-current switching (PLC compatibility), and end-of-stroke indication output. Design engineers are often faced with the challenge of meeting size constraints while maintaining high force requirements. For example, with applications on a harvesting combine, past designs were cavernous enough to allow a large amount of space for hydraulic solutions to actuate the equipment with high force. Now, however, equipment manufacturers are tasked with reducing the overall footprint whilst adding functionality, resulting in an increased demand for more compact components such as the power-dense and intelligent Electrak MD.

The new Electrak MD actuators are available now; more information at www.thomsonlinear.com/md.
