Demand from packaging equipment manufacturers was the driver behind the development of a new smaller, robust and powerful linear actuator, said Thompson.

The T60 Precision Linear Actuator (PLA) is the Swedish company’s latest innovation that is designed to operate in harsh environments such as food packaging thanks to its IP65 rated protection against dirt ingress.

The key feature of the new electro-mechanical actuator is its compact size that allows installation even where space is restricted. The unit, which is used to activate valves, push or pull components or for the precision positioning of ducts, has been designed for smaller machines and measures 75 x 60 mm.

Although more compact than other linear actuators in the PLA range, it offers comparable performance, Thompson European marketing manger Klaus Elsner told FoodProductionDaily.com.

Performance stats

The T60 drives static loads of up to 10 kilonewton (kN) over a stroke length of 1.5 m and permits Y and Z axis loads up to 100 N. High travel speed of 2.5 m/s, combined with repeatability of ±0.05 mm and low 0.11 mm backlash are particularly suited to installation in pick and place systems, said a company statement.

“The T60 does the same job as other PLA models such as the T90 and T130,”​ Elsner added. “It’s a vital addition for machines where there is limited space. We are responding to customer feedback calling for a compact and rugged unit with comparable power. It is also maintenance free which also adds a cost advantage. We believe these attributes make it unique to the market.”

Its IP65 rating means it is protected against both dust and water ingress. With regard to the latter, it means a standard unit can be subjected to extended rinsing processes without compromising reliable operation. Special lubricants are also available for hygienic applications, said Thompson. Its ability to operate at temperatures ranging from -20 to +70 °C makes the T60 suitable for controlled environment food processing environments and thermoforming applications.

The T60 caters for a broad range of industrial applications - from process automation, to food production, electronics and pharmaceutical manufacturing through to the packaging industry, said Thompson.
