Connectors and Wiring Harness Requirements The following tables contain the Caterpillar part numbers for DT inline connector plug and receptacle kits for all available number of pin positions. The kit is comprised of the plug or receptacle and the respective locking wedge. The connector has also been configured for bulkhead mountings and integral component applications (e.g. lamp housing, engine sensor, etc.). Terminal configurations and mounting configurations vary for these applications. Contact the local Deutsch sales contact for more information on these connectors. 5.1.2 Deutsch HD-10 Connectors This circular connector is used for inline and bulkhead applications.
It is more expensive than other connector choices but easier to adapt to wire harness conduit applications (i.e. CSA, Marine, etc.). The connector is available in 3, 6, and 9 terminal configurations. The wire size range the connector will accept is 0.8 mm 2 (18 AWG), 1.0 mm 2 (16 AWG), and 2.0 mm 2 (14 AWG), and 3.0 mm 2 (12 AWG). The plug assembly with interface seal accepts socket terminals and the receptacle assembly accepts pin terminals. Sealing plugs are to be used in unused wire cavities. Ensure that the wires in the plug align with the corresponding wires in the receptacle. Ensure that the index markings on the plug and the receptacle are aligned.
Rotate the plug until the plug slips into the receptacle. Rotate the coupling by approximately 90 degrees until a click is heard. Ensure that the plug and the receptacle cannot be pulled apart.
