DeLOCK RF/EMI Interference Suppression Filter D-Sub 37 pin male to female Gold Plated

The DeLOCK RF/EMI Interference Suppression Filter is a D-Sub 37 pin male-to-female adapter with gold-plated contacts and a silver housing. It integrates broadband low-pass filters to reduce radio frequency (RF) and electromagnetic interference (EMI) on D-Sub interfaces, helping to maintain stable signal transmission for Serial RS-232 / RS-485 and digital or analogue I/O connections.

Advantages

The adapter contains 37 integrated low-pass broadband filters that provide RF/EMI shielding for each pin of the D-Sub 37 interface. Gold-plated contacts ensure reliable electrical contact and corrosion resistance, while the compact adapter format allows direct connection between male and female D-Sub 37 ports without additional cable assemblies.

Suitable for

• Serial RS-232 and RS-485 communication links
• Digital I/O interfaces subject to electromagnetic noise
• Analogue I/O applications requiring reduced interference
• Industrial control and measurement equipment with D-Sub 37 connectors

• Brand: DELOCK, MPN: 66551, EAN: 4043619665518

How to use

Align the male D-Sub 37 pins with the mating female connector and gently fasten the adapter using the connector thumbscrews or mounting screws if available. Ensure both devices are powered off when connecting or disconnecting to prevent transients. Verify the mechanical fit and secure screw connections to maintain shielding continuity and reliable contact.

Recommendations

Use the adapter in environments where RF/EMI may affect signal integrity; for best results, install the adapter close to the affected device and maintain proper grounding of the connected equipment. Avoid excessive bending or mechanical stress on the connector to preserve the gold-plated contacts and filter performance.
