D‑Sub 9‑pin RS232 Serial Connection Cable

The connector is fitted with built‑in metal fixing screws at both ends.
After tightening, it will not loosen due to vibration or pulling force, which is suitable for permanent‑fixed wiring, on‑board vehicle equipment and high‑vibration working environments.
Adopting industrial‑grade galvanized full‑metal shielding, it can effectively suppress signal interference.
Operating temperature range: −40 to 85 ℃. Withstand voltage: AC 1000 V / 1 min. Insulation resistance: ≥ 1000 MΩ.

This cable is used for:
1. Industrial automation (PLC, touchscreen HMI, inverters, servo‑drive commissioning, program flashing, data acquisition)
2. Network operation & maintenance commissioning (Console‑port debugging for switches, routers and firewalls)
3. Automotive diagnostics and on‑board device communication
4. Commercial equipment (access controllers, cash registers, self‑service terminals, industrial printers), etc.
