DB9 to Screw Terminal Adapters | For RS232 & RS485

( number of products: 5 )

Professional RS232 & RS485 connections in seconds. Forget about field soldering.

Tired of time-consuming soldering of DB9 plugs in awkward conditions? Our DB9 to screw terminal adapters (terminal blocks) are an essential tool that allows for instant and secure connection of RS232 and RS485 wires to a COM port using a standard screwdriver.

We offer a full range of variants, including right-angle adapters for tight spaces, ensuring you're prepared for any situation.

An End to Installation Problems...

Whether you're creating a custom cable for an RS485 bus, connecting an RS232 device without a factory plug, or need to quickly diagnose signals on a line, our adapters radically simplify the job. A robust ABS plastic enclosure protects the connections, while the industrial-grade build quality guarantees reliability you won't find in cheap alternatives.

Key Benefits You'll Appreciate on the Job:

Instant Field Installation: Connect wires in seconds using screw terminals, saving valuable time during assembly and service calls.
Universal Application: Perfect for fast wiring of RS232, RS485, and any other communication standards that use a DB9 connector.
Full Compatibility: We offer every variant you might need:
- Male and female connectors
- Screws or nuts mounting for a secure connection
Solution for Tight Spaces: Not enough space behind a device? Our unique DB9 right-angle adapter allows you to connect a cable at a 90° angle, which is invaluable in crowded control cabinets.
Industrial Durability: Our adapters are designed for a wide operating temperature range (-40°C to +75°C), ensuring their reliability in any condition.
