Deutsch DT 12-Way Receptacle Connector – DT04-12PA Standard A-Key Grey Housing
The DT04-12PA is the standard A-keyway Deutsch DT Series 12-way receptacle housing in grey. Providing 12 individually sealed cavities for DT size 16 contacts, this high-density receptacle is the receptacle-half of the DT04-12PA/DT06-12SA mated pair. The 12-circuit configuration makes it the go-to Deutsch connector for ECU main loom interfaces, PDM outputs, and complex multi-circuit engine harness connection points.
12-Circuit DT Receptacle Performance
The DT04-12PA offers the highest circuit density in the standard DT Series range, consolidating up to 12 independently sealed circuits into a single compact connector. Dual-lock contact retention and W12P wedge lock compatibility ensure robust terminal retention even in high-vibration race engine applications. The A-keyway ensures it only mates with the DT06-12SA plug, preventing connector mix-ups in multi-connector loom layouts.
