55621-2

TE Connectivity AMP Connectors's 55621-2 revolutionizes Terminals - Ring Connectors solutions, specifically designed for harsh industrial automation environments. This ruggedized terminal connector combines extreme durability with precision electrical performance for Industry 4.0 applications.The Circular design incorporates triple-sealing technology. Unlike standard connectors, this configuration maintains IP69K protection after 500 mating cycles in contaminated conditions.Engineered for 1/4 Stud interfaces, this terminal features vibration-resistant locking. Testing per IEC 61373 Category 1 shows zero disconnections at 5Grms vibration levels.With 0.040" (1.02mm) wall construction, this component withstands 100N mechanical impact. Finite element analysis confirms uniform stress distribution under shock loading.The 0.431" (10.95mm) dimension includes integrated strain relief. This feature prevents cable fatigue in continuous flexing applications up to 5 million cycles.The 1.561" (39.65mm) measurement accommodates double-crimp termination. This redundant connection method ensures reliability in critical control systems.Designed with Free Hanging (In-Line) orientation, this connector enables tool-less field servicing. The quick-release mechanism reduces maintenance downtime by 40%.The Crimp method creates gas-tight molecular bonds. Accelerated aging tests show <2% resistance change after 10 years in 85 C/85%RH conditions.Supporting 8 AWG range, this terminal features automatic strand alignment. The self-centering design ensures complete conductor capture during crimping.Featuring Insulated technology, this connector resists chemicals and oils. Testing to UL 2267 shows no degradation after 30-day immersion in industrial fluids.The Serrated Termination implementation includes integrated diagnostics. The smart connector design enables real-time contact resistance monitoring via IIoT systems.The Red identification meets ISO 3864 safety standards. Photoluminescent markings remain visible for 90 minutes in total darkness.Manufactured from Copper, the contacts exhibit exceptional arc resistance. The alloy composition prevents welding during short-circuit conditions.The Tin surface treatment withstands abrasive cleaning. Testing demonstrates <0.5 m wear after 1,000 scrubbing cycles with industrial cleaners.
