This DB78 male to female extension cable belongs to the
D‑SUB cable assembly series, built for high‑density signal transmission. High pin‑count D‑SUB 78 connectors are widely demanded in industrial equipment, and this extension cord solves distance‑limitation issues when connecting controllers and peripheral devices.
Unlike generic off‑the‑shelf cables, this DB78 extension harness adopts heavy‑duty cable body, secure locking screws for stable mating, resisting loose connection caused by equipment vibration. Our factory offers full custom service for D‑SUB wiring harness to match your unique project requirements.
