The SMC CDRB2BW20-90SZ-T79L CRB2 Series Rotary Actuator Vane Type is designed for versatile and efficient performance. This actuator allows for flexible auto switch mounting positions, ensuring adaptability to various setups. It supports direct mounting and offers selectable connection port positions, including side ported and axial ported options. When equipped with a switch and angle adjuster, the side ported configuration is utilized. The actuator operates efficiently at low pressures, with a minimum of 0.2 MPa for size 10 and 0.15 MPa for sizes 15 to 40. Additionally, it provides the capability to adjust the angle as needed, enhancing its functionality. The inclusion of an auto switch (Series CDRB2: CDRB2 W, CDRB2 WU) further enhances its operational convenience and precision.
