## Long description

The DeLOCK RF/EMI interference suppression filter is a D-Sub 25‑pin male-to-female adapter with integrated low-pass capacitive broadband filters designed to reduce radio frequency and electromagnetic interference on D-Sub interfaces. It is intended for use with serial interfaces such as RS-232 and RS-485 as well as digital and analogue I/O lines. Connector contacts are gold-plated for reliable conductivity and durability. The adapter is available in green and silver colours.
Advantages
The adapter integrates 15 low-pass broadband filters to provide RF/EMI shielding for the D-Sub interface, minimising signal noise and interruptions. Its male-to-female D-Sub 25 pin configuration preserves pinout compatibility while improving signal stability. Gold-plated contacts enhance conductivity and resist corrosion. Compact adapter design allows inline filtering without additional circuitry.
Suitable for
 Serial RS-232 and RS-485 connections
 Digital I/O lines and fieldbus interfaces
 Analogue signal lines requiring EMI suppression
 Environments where inline RF/EMI filtering is needed
