Product details

DE-9 D-Sub Plug, 6 A per Contact, Gold Flash

The TE Connectivity 5745071-4 is a 9-position D-Sub plug from the AMPLIMITE HD-20 series, configured as a standard DE-9 (E shell size) layout with 2 rows of contacts. It carries a 6 A per contact current rating and a 125 V voltage rating, making it suited for signal and low-power interconnect in industrial control, serial communication (RS-232), and instrumentation applications. The through-hole solder termination and vertical orientation match standard PCB layouts for DB-9 footprints.

The female screwlock (4-40) on the plug side engages with male screwlock hardware on the receptacle or a backshell, locking the pair together.

Frequently asked questions

Where can I buy 5745071-4 available via RFQ confirmation?

The 5745071-4 is sourced to order through independent distribution.

What is the mating connector for 5745071-4?

The mating connector is a standard DE-9 (E shell) D-Sub receptacle with 9 positions, female contacts. The plug uses female screwlocks (4-40) on the mating side, so the receptacle or backshell must have matching male screwlock hardware.

Is 5745071-4 RoHS compliant?

Yes, the 5745071-4 is ROHS3 compliant per the manufacturer listing.

What is the pinout of 5745071-4?

The pinout follows the standard DE-9 (DB-9) layout: 9 positions in two rows (5 on top, 4 on bottom). The exact signal assignment depends on the application (e.g., RS-232 serial), but the physical contact numbering is per the D-Subminiature standard — consult the product drawing for the contact cavity numbering.
