Product details

9-Position D-Sub Receptacle with IDC Termination

The shell size is DE (E), the standard 9-position D-sub footprint, and the housing is free-hanging (in-line) with unthreaded flange holes for panel-mount screws.

Wire Gauge and Current Derating

The 1-745491-9 terminates 20-22 AWG discrete wire via IDC contacts. The current rating is not a single fixed value — it varies by wire gauge, as the smaller 22 AWG conductor has higher resistance and will heat more under load than 20 AWG. For a harness designer, this means the actual current per contact depends on the wire size selected; the 250V voltage rating is consistent across the range.

The free-hanging design allows the connector to be used as a cable-end receptacle without a backshell, though a backshell kit can be added for strain relief and shielding termination if the application requires it.

Frequently asked questions

Where can I buy the TE 1-745491-9 D-sub receptacle?

The 1-745491-9 is sourced to order through independent distribution. Submit an RFQ for current pricing and lead time — availability is confirmed at quote time against your BOM quantity.

What is the wire gauge range for 1-745491-9?

The 1-745491-9 accepts 20-22 AWG discrete wire terminated via IDC contacts. The current rating varies by wire gauge — 20 AWG carries more current than 22 AWG at the same temperature rise.

What is the mating connector for 1-745491-9?

The 1-745491-9 mates with any standard DE-9 D-sub plug (male) having the same shell size and layout. The unthreaded flange accepts 4-40 or M3 jack-screws for panel mounting.
