3. Technical data

Multi-turn actuators SA 07.1 – SA 48.1 / SAR 07.1 – SAR 30.1

Operation instructions AUMA NORM

Multi-turn actuators AUMA NORM require electric controls. AUMA offers the controls AUMA MATIC AM or AUMATIC AC for the

sizes SA(R) 07.1 - SA(R) 16.1. These can also easily be mounted to the actuator at a later date.
