Product details
Optimized for railway signaling systems, 3M's 81M-156-P-A Terminals - Barrel, Bullet Connectors delivers unmatched reliability in mass transit applications. This rugged connector series withstands the extreme vibrations and temperature fluctuations characteristic of rail environments. The 81M-156-P-A is particularly effective for trackside equipment and rolling stock interconnects where failure is not an option.The Male, Pin (Plug) design features vibration-resistant contacts that maintain connectivity under 5G vibration loads, exceeding EN 50155 requirements.Precision-engineered to 0.156" (3.96mm) specifications, the barrel maintains consistent contact pressure despite thermal expansion in outdoor rail applications.Supporting {Wire Grade} railway-approved cabling, this connector handles both signaling currents and high-power applications in modern transit systems.With 0.850" (21.59mm) dimensions, the connector meets strict clearance requirements for trackside installations while allowing for easy maintenance access.The 0.190" (4.83mm) barrel length is optimized for cold-welding termination processes, creating gas-tight joints that resist oxidation.Non-Mating End Insulated materials are halogen-free and meet EN 45545-2 fire safety standards for railway applications.Crimp method ensures reliable connections that withstand 25+ years of service in harsh railway environments.Featuring Butted Seam, these connectors incorporate positive locking mechanisms that prevent accidental disconnection due to vibration.Red coding follows UIC standards for simplified identification in complex railway signaling systems.
