Description

This DB9 male‑to‑male RS232 product is a rugged straight‑through 9‑pin D‑sub cable designed for industrial and EMI‑sensitive applications. It features die‑cast metal shells with nickel or tin finish, metal thumb screws (full metal or plastic head with metal insert options), and a bonded drain wire tied to the shells for reliable chassis grounding. The cable uses nine individually insulated conductors and a robust aluminum‑foil plus tinned‑copper braid shield to maximize EMI protection and signal integrity for TX/RX/GND and handshake lines. 

Image shows gold‑tone contacts for visual reference. Gold plating is optional (specify plating type and thickness on order); standard contact finish may be nickel or gold‑tone. Standard length is 1.5 m; custom lengths and heavier gauge constructions available for long runs.
