DeLOCK RF/EMI Interference Suppression Filter D-Sub 37 pin male to female low-pass filter capacitive

The DeLOCK RF/EMI interference suppression filter is a D-Sub 37 pin male-to-female adapter with integrated low-pass broadband capacitive filtering. It is intended to reduce RF and EMI noise on D-Sub interfaces and to stabilise signal transmission for serial RS-232/RS-485 lines as well as digital and analogue I/O connections. Connectors are plated with brass and gold to support conductivity and durability. The adapter is available in green and silver finishes.

Advantages

The adapter contains 37 low-pass broadband filters that provide RF/EMI shielding for the D-Sub interface, reducing interruptions and signal noise. The capacitive low-pass design is suitable for a wide frequency range and helps maintain signal integrity on serial and I/O interfaces. Brass and gold plating on the connectors improves contact reliability and corrosion resistance.

Suitable for

• Serial RS-232 and RS-485 connections
• Digital I/O interfaces
• Analogue I/O interfaces
• Applications requiring reduced electromagnetic interference on D-Sub 37 pin interfaces

How to use

Connect the D-Sub 37 pin male and female ends between the devices or cable assemblies where RF/EMI suppression is required. Ensure secure fastening of the D-Sub screws to maintain reliable electrical contact. Use in-line on serial or I/O cabling to reduce interference and preserve signal integrity.

Recommendations

Use the adapter in environments where RF/EMI may affect serial RS-232/RS-485 or analogue/digital I/O signals. Verify connector pinouts and secure mechanical connections; do not force connectors or exceed the intended application for signal types.
