CBTY31FN Push-Pull Connector for Surgical Robots 2026: Custom Cable YH-C21046-1031F-35 with CBTY31FN-KMSM12-D72B and CBUP2UR-KMSM09-D72B for USA Client
The CBTY31FN-KMSM12-D72B is a CBTY31FN push-pull connector for surgical robots — a miniature Size 31 waterproof plug (outer diameter approx. 13 mm) on a custom 1.9-meter cable assembly, exceptionally lightweight so surgeons feel virtually no cable resistance when handling the device or manipulating robotic joints, with a 12-pin signal layout that reliably supports serial data from high-precision joint encoders. Every specification in this guide is backed by the surgical robotics interconnect engineering of Spring Technology.
Pain point: Wiring the handle of a robot-assisted surgical system — where the cable must be so light and small that surgeons feel no resistance while manipulating robotic joints, yet still carry 12 pins of high-precision encoder serial data without failure?
Core answer: For a US client’s robot-assisted surgical system, Spring Technology designed the custom cable YH-C21046-1031F-35, built with a CBTY31FN push-pull connector for surgical robots at the handle end. It features a 12-pin connector (CBTY31FN-KMSM12-D72B) at one end and a 9-pin connector (CBUP2UR-KMSM09-D72B) at the other, connected by a 1.9-meter cable. Suitable for applications such as robotic surgical handle cables, it utilizes a miniature Size 31 connector (outer diameter approx. 13 mm) that is exceptionally lightweight; this ensures surgeons experience virtually no cable resistance when handling the device or manipulating robotic joints, while the 12-pin signal configuration reliably supports serial data transmission from the joints’ high-precision encoders.

2. Surgical Robot Connector Design Highlights
Surgical robotic handles demand cables that disappear in the surgeon’s hand. The design highlights below are why this CBTY31FN push-pull connector for surgical robots is specified for robot-assisted systems:
- Miniature Size 31 shell — the approx. 13 mm outer diameter keeps the handle slim and ergonomic.
- Exceptionally lightweight — surgeons experience virtually no cable resistance when handling the device or manipulating robotic joints.
- 12-pin encoder serial data — the 12-pin signal configuration reliably supports serial data transmission from the joints’ high-precision encoders.
- Waterproof TYN platform — rugged and sealed for the demanding surgical environment.
- 1.9-meter custom cable — the YH-C21046-1031F-35 assembly matches the reach and routing of the surgical system.
- Gold-plated contacts — stable signal paths for precise encoder feedback.
