91911-31231LF

The 91911-31231LF from Amphenol ICC (FCI) revolutionizes Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) for medical device applications. This biocompatible connector solution meets ISO 13485 standards, offering exceptional reliability for life-critical systems while enabling miniaturization of portable medical equipment.Medical-grade Header, Center Strip Contacts design incorporates features that prevent fluid ingress and bacterial growth. The smooth surfaces facilitate cleaning while maintaining >10G insulation resistance after sterilization cycles.Available in 31 configurations, the connector supports both low-power sensor interfaces and high-current therapeutic device requirements. The isolated power contacts prevent leakage current in patient-connected applications.The 0.039" (1.00mm) spacing has been optimized for medical PCB layouts requiring high-density interconnects. The anti-wicking design prevents fluid migration between adjacent contacts.The 2 row architecture provides optimal signal isolation for sensitive biopotential measurements. This configuration reduces crosstalk to levels suitable for ECG and EEG applications.Designed for Surface Mount installation in medical devices, the connector withstands repeated sterilization processes. The materials are compatible with ethylene oxide, gamma radiation, and steam autoclave methods.Critical Board Guide, Solder Retention include radiopaque markers for X-ray detection and color-coded mating guides. These medical-specific enhancements improve device safety and usability in clinical environments.The Gold or Gold, GXT™ formulation prevents oxidation while maintaining biocompatibility. Extensive testing confirms no cytotoxic effects according to ISO 10993-5 standards.With 15.0µin (0.38µm) protection, the contacts maintain stable performance through 10,000 mating cycles. This durability is essential for frequently disconnected portable medical devices.Flexible 4.5mm options accommodate various enclosure designs in medical equipment. The stackable configuration supports modular device architectures.The 0.048" (1.22mm) profile allows for proper cleaning under the connector in surgical instruments. This design consideration prevents biological material accumulation.
