Festo DSM-16-270-P Rotary Actuator Vane Type 270° Pneumatic Drive 159541

Festo DSM-16-270-P Rotary Actuator Vane Type 270° Pneumatic Drive 159541

The Festo DSM-16-270-P is a vane-type pneumatic rotary actuator with a 270° rotation angle and a 16 mm bore. It converts compressed air pressure into controlled rotary motion through an internal vane mechanism, delivering a defined angular output at the splined shaft. Dual adjustable end-stop cushion screws allow the rotation arc to be fine-tuned within the 270° range for precise positioning in automated systems.

Applications

Festo DSM-series vane rotary actuators are widely used in factory automation and machine-building applications where a controlled angular movement is needed from a pneumatic drive source. Common uses include pick-and-place end-of-arm tooling, part-indexing stations, clamping and turning fixtures, and valve actuation in process lines. The DSM-16-270-P's 270° swing angle makes it well suited for applications requiring a wide rotational range — such as part transfer between two positions more than 180° apart — while the adjustable end stops let engineers dial in precise start and stop positions without additional mechanical stops. Festo's DSM series has been a standard component in European and North American automated assembly lines and handling systems since the 1990s and remains in current production and widespread service use today.
