Product details
3M's SS-31-4-NB delivers breakthrough Terminals - Spade Connectors technology for railway signaling systems. This vibration-resistant connector meets EN 50155 standards while providing fail-safe performance in electrified rail environments. Its robust design addresses the unique challenges of trackside and rolling stock applications.The Spring, Snap configuration provides positive locking that withstands 30G shock loads. The spring-loaded design maintains contact pressure during constant vibration.Engineered to 4 Stud railway specifications, this terminal prevents micro-arcing in 25kV AC environments. The arc-resistant housing contains internal flashovers.Precisely manufactured to 0.250" (6.35mm) dimensions, this connector prevents snow and ice accumulation. The self-cleaning design maintains operation in -40 C conditions.The 0.870" (22.10mm) profile incorporates crash protection that meets EN 15227 standards. This safety feature is critical for collision scenarios.Optimized for Free Hanging (In-Line) installations, this connector enables tool-less maintenance in depot conditions. The color-coded alignment prevents incorrect mating.Utilizing Crimp technology, this connector achieves cold-weld joints that survive 10^8 vibration cycles. The process is qualified for high-speed train applications.Designed for 18-22 AWG railway cabling, this terminal maintains signal integrity in 25kV EM fields. The filtered design rejects traction noise up to 150dB.The Insulated material exceeds EN 45545-2 fire safety requirements. Special ceramifying compounds maintain circuit integrity during fire incidents.The Red coding follows UIC railway standards for quick identification. This system reduces troubleshooting time in complex signaling networks.
