Product Description
The DB9 Male to Screw Terminal Adapter is a rugged, industrial-grade solution designed to simplify serial connectivity in the field. This breakout board eliminates the need for tedious soldering or specialized crimping tools, allowing you to connect bare wires directly to a standard DB9 interface using only a small screwdriver.
Engineered for reliability, the board breaks out all 9 pins of the DB9 connector plus the shield (GND), providing a clear, labeled path for RS232, RS422, or RS485 communication. Whether you are performing on-site maintenance on a PLC, wiring a custom serial sensor to a controller, or prototyping a new communication interface, this adapter ensures a secure, vibration-resistant connection. Its compact design and integrated strain relief make it the definitive choice for engineers and technicians requiring a fast, “plug-and-play” serial wiring solution.
Key Features
- Solderless “Quick-Connect” Design: Features high-quality screw terminals for fast, secure wiring without the need for soldering irons or heat shrink.
- Full 9-Pin Breakout + Shield: Provides access to all pins (1-9) plus a dedicated terminal for the cable shield/case ground to ensure signal integrity.
- Clear Silk-Screen Labeling: Each terminal is clearly numbered and labeled, significantly reducing wiring errors during installation and troubleshooting.
- Industrial Build Quality: Constructed with a high-durability DB9 male head and a FR-4 fiberboard PCB for long-term stability in harsh environments.
