The SMC AS500 series consists of elbow-type speed controllers designed for precise regulation of pneumatic actuator speeds. These controllers feature an integrated one-touch fitting, which dramatically simplifies installation by allowing for quick, secure tubing connections without tools. The 90-degree elbow design is particularly advantageous in space-constrained applications, enabling a more compact and organized pneumatic circuit layout. Engineered for durability and reliability, the AS500 series provides stable meter-out flow control, ensuring consistent and accurate performance in a wide range of industrial automation environments.
