AUTOMATION & TESTING

Installation and Operational Qualification of Lumax S-Cable Automated Test Equipment

Cooper Surgical required a validated automated test system for Lumax S-Series fiber optic extension cables used in surgical catheter applications. The challenge involved designing and qualifying a custom test system that could perform comprehensive optical and pneumatic testing without requiring external optical measurement equipment or reference standards. Critical concerns included ensuring accurate optical throughput measurements for fiber optic cables, detecting optical crosstalk between fiber channels, measuring pneumatic leakage and flow rate within tight tolerances, detecting pneumatic obstructions in cable pathways, integrating with existing Lumax Catheter ATE database via Ethernet, achieving self-calibration capability without external equipment, and providing an operator-friendly touchscreen interface for production environments.
