Festo’s new DRVS semi-rotary drive and matching SRBS position sensor

Festo introduced a pneumatic semi-rotary vane drive and matched contactless position sensor.

Standard swivel angles for the DRVS semi-rotary drive are 90, 180, and 270 degrees. Custom swivel angles are possible with a stop bracket accessory. At six bar pressure, the seven different sizes in the DRVS line deliver a torque range of .15 Nm to 20 Nm. The company guarantees overnight shipping for standard DRVS drives, which lowers inventory requirements for OEM.

The SRBS, a compact, contactless magnetic position sensor, attaches to the DRVS via a single cable and three screws. During installation, personnel simply move the vane to the drive’s two positions and with a few clicks of the SRBS push button both positions are located for the position sensing unit. Repetition accuracy is < .0039 inches (.1 mm). Through its push button, the SRBS position sensor can be designated PNP or NPN and NO or NC, which means that one part number covers all the different combinations.
