Festo DSM-8-180-P-A-FF-FW Rotary Actuator (Order Code: 185939)<\/h1>\n
<\/div>\n

Product Overview<\/h2>\n
<\/div>\n
The Festo DSM-8-180-P-A-FF-FW (Order Code: 185939) is a compact, rack-and-pinion style rotary actuator from the DSM series, engineered for precise 180\u00b0 angular motion in small-scale industrial automation applications. With an 8 mm bore size and double-acting operation, it delivers consistent torque for light-duty positioning tasks such as part rotation, valve actuation, and small gripper orientation. The actuator features integrated adjustable end-position cushioning, a central piston rod thread for easy load mounting, and compatibility with Festo proximity switches for position feedback. Compliant with RoHS and designed for low corrosion stress (CRC 1) environments, it offers universal mounting flexibility and robust performance across a wide temperature range, making it ideal for compact assembly lines, robotics end-effectors, and lab automation setups.<\/div>\n

Function<\/th>\nDescription<\/th>\n<\/tr>\n<\/thead>\n
Precise 180\u00b0 Angular Actuation<\/td>\nDelivers repeatable 180\u00b0 rotary motion via a rack-and-pinion mechanism, ensuring accurate positioning for light-duty automation tasks.<\/td>\n<\/tr>\n
Double-Acting Torque Generation<\/td>\nProduces bidirectional torque for both clockwise and counterclockwise rotation, enabling versatile motion control for part handling and orientation.<\/td>\n<\/tr>\n
Adjustable End-Position Cushioning<\/td>\nIntegrated pneumatic cushioning at both rotation ends minimizes impact, noise, and component wear, enhancing operational stability and service life.<\/td>\n<\/tr>\n
Position Detection Compatibility<\/td>\nFeatures mounting slots for Festo proximity switches, enabling real-time position feedback and seamless integration with PLC-based control systems.<\/td>\n<\/tr>\n
Compact Load Mounting<\/td>\nCentral M3 piston rod thread and flange\/wide flange (FF-FW) design allow direct, space-saving mounting of small loads and accessories.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n
