A key feature of AUMA’s new SGC and SVC actuators displayed on the company’s booth is their compact design

A key feature of AUMA’s new SGC and SVC actuators displayed on the company’s booth is their compact design: this is made possible by coaxial arrangement of an ellipto-centric gearing equipped with a permanent magnet motor. All components for controlling the actuators, including local controls, are contained in a single housing. The design makes the products particularly appropriate for installations with space constraints. The actuators are available with parallel interface, but can also be equipped with Profibus DP and Modbus RTU interfaces.

An ‘end stop’ principle developed and proven by AUMA has been optimised for the company’s GS gearboxes and this news is also promoted at Wasser Berlin. The new block stop construction prevents end position seizures which were difficult to release in certain conditions e.g. in the event of automatic tripping failure. Safety wedge discs ensure that the required amount of unseating torque is just 60 % of the torque applied to approach the end stop.

Further developments promoted by AUMA include enhanced corrosion protection. Two-component powder coating is one of the crucial elements fulfilling the requirements of corrosivity category C4 (high) in compliance with EN ISO 12944-2 for AUMA’s basic version actuator.
