DeLOCK RF/EMI Suppression Filter D-Sub 9-Pin Plug to Socket Inductive Low-Pass

The DeLOCK RF/EMI Interference Suppression Filter is a D-Sub adapter with integrated low-pass broadband filters designed to reduce RF and EMI noise on D-Sub connections. It is available in a 9-pin male-to-female configuration with brass contacts and gold plating, and is intended for use on serial interfaces such as RS-232/RS-485 as well as digital and analogue I/O lines.

Advantages

The adapter contains nine low-pass broadband filters that provide RF/EMI shielding for the D-Sub interface, reducing interruptions and signal noise. Its D-Sub 9 pin male-to-female form factor and metal housings in blue and silver make it suitable for direct inline connection without additional components.

Suitable for

• Serial RS-232 and RS-485 connections
• Digital I/O signal lines
• Analogue I/O interfaces prone to interference
• Applications requiring inline EMI suppression on D-Sub 9 pin connectors

How to use

Connect the male D-Sub 9 pin end to the corresponding female port and attach the female D-Sub 9 pin end to the mating male connector on your device or cable. The adapter works inline and requires no configuration; the integrated low-pass filters suppress RF/EMI automatically during normal operation. Ensure connectors are firmly fastened to maintain a stable connection.

Recommendations

Use the adapter in environments where RF or electromagnetic interference affects signal integrity. Verify connector pinout compatibility before insertion and avoid excessive mechanical stress on the connector to preserve the shielding and plating.
