Introduction
The D-Sub 9-pin connector cable, a staple in serial communications (RS-232), links devices like computers, printers, PLCs, and legacy industrial equipment. Featuring a robust D-shaped metal shield, these cables ensure reliable data transfer via 9 contacts and support Male-to-Male (DTE-DCE), Male-to-Female (adapters/extenders), or Female-to-Female (port converters) configurations. Custom options include wire gauges (22–28 AWG) for voltage and current needs, lengths (0.3–15 m), and shielded jackets for EMI resistance. Available in Black, Blue, Red, or White for easy identification, they’re ideal for embedded systems, point-of-sale devices, CNC machinery, and retro computing. Durability is enhanced with gold-plated contacts and molded strain relief.
