Two silver DB9 male connectors with screw-lock metal shells and solderless terminals

BONAEVER

BONAEVER 2PCS DB9 Breakout Connector Solderfree RS232 Male Adapter Silver

SKU CH-GQA4-PWT7T

Two solder-free DB9 male adapters with zinc-alloy shells and screw-locked cases create reliable serial links for industrial and office equipment

  • Product colorSilver
  • Solderless terminals simplify wiring without a soldering iron
  • Zinc alloy shell resists pressure and high temperature
  • Pure copper plated joints ensure reliable contact and long life
  • Screw-locked case prevents gaps and loose closure
  • Connects serial devices such as PLCs, modems and barcode scanners

DB9 Solderless Breakout Pair

Two silver DB9 male adapters arrive in a single pack, each featuring a solderless 128-type copper terminal block inside a zinc-alloy shell. They let technicians terminate custom-length serial cables without a soldering iron, making them suited for field service, lab bench work and permanent installations where RS-232 links must be assembled quickly.

Replaces Soldered DB9 Terminations

The screw-terminal design removes the need for a hot iron, flux and heat-shrink, so rework time drops dramatically when a pinout changes or a cable is damaged. The jump is worth it whenever a project demands repeated connector changes, vibration-resistant joints or a clean, tool-free build in tight enclosures.

Handles Standard Serial Wiring

Each connector accepts nine discrete wires for full RS-232 pinouts, supporting links to PLCs, modems, barcode scanners, industrial instruments and similar gear. It runs out when the application requires high-density multi-port panels, shielded twisted-pair terminations or automated crimp-to-wire processes that demand a different connector format.

Questions about this item

What cable diameter fits the 128-type terminal openings on this DB9 breakout connector?

The 128-type copper terminals accept stripped wires without soldering; match the wire gauge to the terminal aperture for a secure crimp.

Which step do installers most often skip when assembling the zinc-alloy shell with screw lock?

Tightening the shell screws and nuts fully so the metal case closes without gaps, ensuring the anti-interference shield is effective.

When should the pure copper plated joints be inspected or replaced in a permanent RS232 installation?

Check the joints if signal errors appear or after repeated mating cycles; the plated copper is rated for long life but wear eventually degrades contact.
