Product details

9-Position Right-Angle D-Sub Plug for Signal Interconnects

The steel shell with tin plating and integral grounding indents provides a low-impedance path to the chassis ground, bleeding shield currents before they reach the signal pins.

Rated 6A per Contact at 125V — Signal Duty with Headroom

Each contact is rated 6A at 125V, which puts this plug squarely in signal-level territory — enough for control loops, serial data, and low-power I/O, with margin above the typical 1-2 A draw of a single RS-232 line. The gold flash finish on the brass contacts handles the mating cycle count of a field-serviceable connector without the cost of a heavy gold plate; for environments with frequent reconnects or corrosive atmospheres, the flash layer provides adequate protection for the expected service life of a D-sub in an enclosure.

Right-Angle Solder Termination for Board-Edge Mounting

The 0.590" (14.99 mm) backset spacing sets the distance from the board surface to the mounting flange — a dimension that must match the panel cutout and the mating receptacle's shell length. The 4-40 threaded inserts on the housing flange accept standard D-sub jackscrews for mechanical retention against vibration and cable strain.

Frequently asked questions

Where can I buy the TE 5745990-3 D-sub plug?

Submit a request for quote to confirm current availability and pricing for your BOM quantity.

What connector mates with the 5745990-3?

This plug mates with a standard DE-9E (DB-9) D-sub receptacle — the same shell layout used across the AMPLIMITE HD-20 series. The mating half must have a 4-40 threaded insert pattern to match the flange feature.
