Premier Cable PCM-S-0788 Micro DB9 Male to Male RS232 Serial Cable for Industrial Automation

Detailed Product Description

The Micro DB9 Male to DB9 Male Cable is a highly reliable 9-pin D-SUB serial communication cable featuring a Micro DB9 male connector and a standard DB9 male connector, enabling stable data transmission between devices.

Designed for RS232 serial connections in industrial control equipment, automotive electronic testing systems, communication devices, and automation equipment.

Featuring a shielded cable structure, it effectively reduces external interference and ensures stable communication performance, making it suitable for equipment debugging, data communication, and system maintenance applications.

Design Purpose

Why Was This Cable Designed?

1 Extreme Space Efficiency

As modern industrial hardware trends towardminiaturization, standard DB9 interfaces consume too much panel space. The Micro DB9 profilereduces the connector footprint by over 50%, enabling high-density port deployment.

2 Flawless Signal Integrity

Industrial environments are prone to electricalnoise from motors and inverters. PCM-S-0788 utilizes heavy-duty shielding to deliver error-free,packet-lossless RS232 data streams amidst heavy interference.

3 Mechanical Reliability Against Vibration

Machinery vibration can easily loosen standard friction-fit lines. The molded thumb-screws provide a rigid mechanical lock, ensuring the cable remainsanchored during continuous 24/7 manufacturing operations.

Precision Craftsmanship

High-Grade Conductors	Built with pure tinned copper cores(e.g., 28AWG/30AWG) to minimize signalattenuation and resistance.
Gold-Plated Contacts	Pins feature thick gold plating for superior oxidation resistance, anti-corrosion, and long-lasting durability over thousands of mating cycles.
Double Shielding	Equipped with an aluminum foil and high-density braided mesh shield to suppresselectromagnetic interference (EMI) and radio frequency interference (RFI).
Ruggedized Outer Jacket	Wrapped in a wear-resistant, flexible PVC jacket with fully molded strainreliefs and integrated thumb-locking screws to prevent accidental disconnection.
