Description

Product Description

The DB9 Female to Screw Terminal Adapter is a rugged, industrial-grade solution designed to simplify serial connectivity and field wiring. This breakout board eliminates the need for tedious soldering or specialized crimping tools, allowing technicians to connect bare wires directly to a standard 9-hole DB9 interface using only a small screwdriver.

Engineered for maximum versatility, the board breaks out all 9 pins plus the shield (GND), providing a clear, labeled path for RS232, RS422, or RS485 communication. Its compact, low-profile design is perfect for space-constrained enclosures, while the high-quality screw terminals ensure a vibration-resistant connection in demanding environments. Whether you are performing on-site maintenance on a PLC, wiring a custom sensor to an industrial controller, or prototyping a new communication bridge, this adapter provides a secure, “plug-and-play” serial wiring solution.

Key Features

Tool-Free Solderless Termination: High-quality screw terminals allow for fast, secure wiring without a soldering iron or heat shrink.
Full 9-Pin + Shield Breakout: Provides access to all 9 pins (1-9) plus a dedicated terminal for the cable shield/case ground to ensure signal integrity and noise reduction.
Precision Labeled PCB: Each terminal is clearly numbered and silk-screened to match standard DB9 pinouts, significantly reducing wiring errors during installation.
Industrial Build Quality: Constructed with a high-durability DB9 female socket and a FR-4 fiberboard PCB for long-term stability in harsh conditions.
Vibration Resistant: Screw terminals provide a high-torque grip on wires, making it ideal for use in machinery, transit, or robotics subject to constant movement.
Universal Protocol Support: Physically compatible with any protocol using a DB9 interface, including RS232, RS485, RS422, and CAN Bus.
