BDD DE9P DB9 Male Solderless D SUB Breakout Connector Thumb Screws

The BDD DE9P Thumb Screw D-SUB is a practical solderless DB9 male breakout connector designed for quick, convenient, and reliable cable termination in serial communication and electronic wiring applications. This field termination kit features a male 9-pin D-Sub connector on one end and a screw-down terminal block on the other, allowing users to connect raw wires without soldering or crimping individual contacts.

The connector is suitable for RS232 serial applications and other compatible 9-pin D-Sub interfaces. Its screw-terminal design simplifies installation, maintenance, and cable replacement, making it useful for technicians, installers, electronics hobbyists, and industrial control applications.

With a 1:1 pin assignment, 3.81mm terminal pitch, and compatibility with 26-18 AWG cable, the BDD DE9P connector provides a straightforward method of connecting wires to a DB9 male interface. The included case and thumb screws contribute to a practical, user-friendly connection solution.

Connector Design

The BDD DE9P connector combines a male DB9 serial interface with a screw-terminal breakout arrangement. Instead of soldering wires directly to connector contacts, users can insert the individual conductors into the screw terminals and tighten the screws to secure the connection.

The 1:1 pin assignment provides a direct correspondence between the DB9 connector pins and the terminal positions, making it easier to identify and wire the appropriate connections.

The 10-pin terminal block provides an additional terminal position beyond the nine signal pins. The exact use of the additional terminal should be confirmed against the connector's wiring layout and application requirements.

RS232 and Serial Applications

This breakout connector is suitable for compatible RS232 serial communication systems where a DB9 male interface is required. It can be used to simplify the connection of individual wires to a serial port or compatible electronic device.

Potential applications include:

• RS232 serial communication wiring.
• Industrial control equipment.
• Electronic test and measurement equipment.
• Computer and peripheral serial interfaces.
• Custom serial cable assemblies.
• Equipment maintenance and repair.
• Electronics prototyping and development.
• Control panels and automation projects.

Compatibility note: The connector's physical DB9 interface does not guarantee compatibility with every DB9 application. Confirm the required pinout, electrical interface, and wiring configuration before connecting equipment.

Installation and Wiring

The BDD DE9P Thumb Screw D-SUB is designed for straightforward field termination.

1. Prepare the cable by stripping the insulation from the individual conductors.
2. Identify the required wires and their corresponding pin positions.
3. Insert each conductor into the appropriate screw terminal.
4. Tighten the terminal screws to secure the wires.
5. Check the wiring against the required 1:1 pin assignment.
6. Close the protective case and secure the connector using the supplied thumb screws where applicable.
7. Test the completed connection before placing the equipment into service.

Always verify the pinout and ensure that the connected equipment is powered off during installation.

Cable Compatibility

The connector supports cable gauges from 26 AWG to 18 AWG, providing flexibility for a variety of signal and control wiring applications.

The 3.81mm terminal pitch allows for convenient access to the screw terminals while maintaining a compact connector arrangement. Select cable types appropriate for the electrical requirements of the intended application.

Operating Temperature

The specified operating temperature range is -20 C to +105 C. This indicates the stated temperature range for the connector's intended operation. Actual suitability depends on the surrounding environment, cable insulation, installation conditions, and the requirements of the connected equipment.

• Thumb Screws.

Important Information

• This product is a connector and cable termination accessory, not a complete serial communication device.
• Confirm the required pinout and electrical compatibility before use.
• The 1:1 pin assignment refers to the connector-to-terminal correspondence.
• The supplied specifications do not establish a specific electrical performance rating for every application.
• Ensure that all screw terminals are securely tightened before operation.
• Dimensions are approximate and may vary slightly due to manufacturing tolerances.
