QR/P1-PC2A-111(12)

The QR/P1-PC2A-111(12) by Hirose Electric Co Ltd 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 Signal 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 Crimp 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.Engineered for 24-28 AWG railway cables, the connector accommodates both European (EN 50264) and North American (UL 1685) cable standards. The integrated fire barrier maintains circuit integrity for 180 minutes at 850 C.The Gold 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.
