Connector series for conveying control and indication signals

TE Connectivity's MU27P Connector Series is Multiple Unit connectors that comprise a 27 pin receptacle, plug and 'dummy' receptacle that are used to convey the locomotive functions between units. These connectors are available now from Mouser. Twenty-seven point trainline connectors provide a single point in the train to distribute up to 27 commands to some or all of the vehicles simultaneously. The company's connectors are used to convey control and indication signals for doors, public address, brake applied/released, as well as audio and other passenger rail functions. These connectors are intended to accept three 10AWG lead with all other leads being 12AWG or 14AWG and enable the connectors to be completely interchangeable and intermateable with other brands adhering to the AAR-S-512 specification. The connectors are key to preventing intermating of different wiring configurations.
