Cole Hersee Co offers its 13-pole plug and socket by providing six extra contacts within the standard configuration of a tractortrailer connection. The 13-pole plug eliminates risk of misconnection by enabling operators to connect all trailer circuits with just one plug.
This plug surpasses SAE J560b performance standards and conforms to the requirement of interchangeability between 13- and seven-pole sockets. The seven standard diameter contacts use Cole Hersee's SpringGrip design, with a self-adjusting spring band to provide uniform contact with socket pins. The six small-diameter contacts carry up to 25 amps and maintain multiple contact points between plug and socket. Contacts float for proper engagement with all mating sockets.
The 13-pole plug adapts to various wiring combinations, including a twisted pair for advanced communication applications. A glass-filled, plastic construction prevents rust and corrosion, and an O-ring at the plug's end prevents moisture from reaching the contacts. A strain relief and grommet seal isolate the connections on the terminal from mechanical strain and provide additional moisture protection.
