The Branson Gold Booster 900/2000 Series (Part No. 101‑149‑052) is an aluminum O-ring booster designed specifically for 20 kHz ultrasonic welding systems within the 900, 2000, and 2000X series. Its gold color coding denotes a 1:1.5 amplitude gain, meaning it amplifies the ultrasonic signal by 50%. It features a 1/2‑20 threaded interface on both the converter and horn ends and aligns with Branson’s color-coded booster system for easy identification and integration.
