DT Series Connectors

Deutsch DT Series connectors are sealed rectangular connectors used for reliable power and signal connections in vehicle, machinery and industrial wiring harnesses. The DT Series commonly uses Size 16 contacts and includes a wide range of plug and receptacle housings, position counts, keying options and mounting configurations.

Use the filters below to narrow the range by number of positions, connector style, contact type, keying, mounting type and application and identify the correct DT housing before selecting compatible contacts, wedgelocks and other assembly components.

If you are still deciding whether DT is the right connector family, compare DTM and DTP, or read our DT vs DTM vs DTP connector guide.

Choose the Right Deutsch DT Series Connector

Choosing the right Deutsch DT connector starts with the harness configuration. First select the number of circuits required, then confirm whether you need a plug or receptacle housing, the required contact configuration, keying and mounting style.

DT Series housings commonly use Size 16 contacts, but the exact contact and wire compatibility should always be checked against the individual connector and terminal specifications. Once the housing is selected, complete the assembly with compatible contacts and terminals, wedgelocks, seals and accessories and any required backshells.

For smaller signal and sensor connections, explore Deutsch DTM Series connectors. For circuits requiring the larger Size 12 contact system, browse Deutsch DTP Series connectors. If you need help choosing between the three families, see our DT vs DTM vs DTP comparison guide.
