The DT04-12PB-CE07 is a 12-cavity receptacle connector from the DT series, featuring an enhanced B key configuration with black housing and reduced diameter seals for improved environmental sealing. This connector is designed for reliable mating with corresponding plug connectors in harsh industrial and automotive environments. The product includes an end cap for protection when not mated, and is compatible with the W12P wedge/TPA secondary locking system for secure contact retention. The 16 contact size accommodates standard automotive-grade wire gauges and is widely used in power distribution, signal transmission, and control systems in transportation and industrial equipment where robust, sealed connections are essential.
