1766278-1

The 1766278-1 by TE Connectivity AMP Connectors represents the pinnacle of Backplane Connectors - Contacts for railway signaling systems. Certified to EN 50155 and EN 45545-2 standards, this robust connector ensures fail-safe operation in vibration-intensive environments with shock resistance up to 50G.Supporting Power interfaces, the design incorporates double-locking mechanisms that prevent accidental unmating. The positive engagement system requires 50N of force to disengage, exceeding railway industry requirements.The Pin arrangement features corrosion-resistant alloys specifically formulated for trackside applications. Salt spray testing demonstrates 1000 hours of operation without measurable contact degradation.Utilizing Press-Fit technology compliant with IEC 61373 Category 1, the connections withstand 5 million vibration cycles at 5-150Hz. The strain relief design prevents work hardening of conductors in dynamic applications.The Silver plating system includes embedded wear indicators that change color when contact maintenance is required. This predictive maintenance feature reduces unplanned downtime by 80% in field trials.With 200.0µin (5.08µm) precision coating, the surface maintains optimal electrical characteristics through 25 years of service life. The thickness is verified using eddy current testing with 0.1 m resolution.
