77427-121LF

Amphenol ICC (FCI)'s 77427-121LF sets new standards in Backplane Connectors - Contacts for industrial automation systems. Designed with ruggedized construction, this connector maintains signal integrity in electrically noisy environments while supporting Industry 4.0 protocols. Its modular design allows flexible configuration for various fieldbus applications.Supporting Coaxial interfaces, the connector features patented shielding technology that reduces RF leakage by 40dB. System integrators benefit from its broad compatibility with industrial communication standards.The Pin, Center implementation utilizes dual-beam contact geometry, providing redundant contact points. This design philosophy increases reliability by 60% compared to single-point contacts in vibration-prone installations.Utilizing Solder technology, the connection system achieves gas-tight joints with contact resistances under 2m . This is particularly crucial for precision sensor networks in process control applications.Engineered for RG-174, 188, 316 wiring, the insulation displacement mechanism ensures consistent termination force ( 0.5N). Field technicians appreciate the tool-less installation capability for rapid maintenance operations.The Gold surface treatment undergoes accelerated aging tests simulating 20 years of operation. Test results demonstrate contact resistance drift remains below 3% in temperature cycling from -40 C to +125 C.Precision-controlled 51.2µin (1.30µm) deposition guarantees optimal fretting corrosion protection. The thickness tolerance is maintained within 0.05 m across all production batches.
