Overview
The SITO DRIVE TA-52 rotary actuator is a face-mount unit for robotic motion applications. Select a transmission ratio of 50 or 100 and choose a version with or without brake. Both versions use CAN 2.0B communication at 1M bps and operate from a 10–60 V supply (24 V recommended). The 52 mm-diameter body includes an 8 mm hollow bore.
