MIL-DTL-5015 Type Reverse Bayonet Connectors
At their most basic level, rail system interconnect design challenges are similar to other transport modes. Reducing weight is a critical issue, especially for high-speed and Maglev rail systems. Shielding electromagnetic interference is important, especially in sensitive electronic systems such as engine monitoring and diagnostic sensors. Basic mechanical protection of cables, conductors and contacts is a standard requirement especially when frequent mating and unmating is required, or when cables are routed through exposed intercar or undercar locations. To ensure rapid and accurate car linking and cabin reconfigurations, interconnects must be easy to couple and keyed to avoid mis-mating. Vibration, shock and connector decoupling problems are also common in rail applications, and require focused attention when selecting shell materials and mating technologies. As passenger and crew safety is paramount – interconnection systems must not compound flammability, smoke or toxicity risks.
But make no mistake: the overriding challenge is environmental. Rail and transportation systems represent one of the most challenging environments for the long-term survivability and reliability of interconnect cables and assemblies. From high-speed rail transportation systems to heavy railway freight lines, the standard daily fare of the rail industry is one harsh environmental challenge after another.
Electrical and signal interconnections in rail car linkages, for example, are subject to significant environmental abuse. Undercar cables, exposed to splashing, mud, diesel exhaust and high heat, require extremely robust environmental protection. Locomotives are brutal testing grounds for cable systems which are subjected to hot oils, solvents, and fuel spills, not to mention high heat and other environmental stress factors. In fact, it's fair to say that the harsh environment of a locomotive engine compartment is where poorly designed or minimally protected interconnect cables go to die.
For this reason, the art of designing rail industry interconnect cables that provide long-life and value depends on a comprehensive understanding of the environmental stress factors that can, at a minimum, diminish performance, and at their worst lead to complete system failure. Glenair is an expert in the design of cable, box and conduit wire protection systems that prevent environmental damage and ensure longevity of service. The design and manufacture of environmentally sealed connectors, backshells and other components that keep interconnect systems free of corrosion has been our bread-and-butter business for over 50 years.
This catalog presents one of the core Glenair interconnect technologies that is specifically geared for use in rail systems, agricultural equipment, military vehicles and other harsh, environmental applications. Glenair Series ITS and ITS-RG connectors are perfectly suited to address every rail industry interconnect challenge. These ruggedized, MIL-DTL-5015 Type reverse bayonet connectors are deployed in virtually every rail industry sub-system.
