2.54mm pitch Dustproof Covers M2052 series

The HRB M2052 series includes 90° and 180° dustproof covers, specially developed for standard 2.54mm pitch IDC connectors. Manufactured from high-quality flame-retardant Nylon 66 that meets UL94V-0 standards, these covers deliver outstanding insulation, anti-aging and wear resistance for long-term reliable use.
Adopting a precision snap-fit structure, they can be installed and removed easily without extra tools, and lock tightly to avoid falling off under vibration. As effective protective accessories, they block dust, moisture and debris from entering the contact area, preventing terminal oxidation, corrosion and poor electrical connection.
Available in white color and full pin range from 2P to 24P, this series is widely applied in industrial control systems, home appliances, communication equipment and other electronic devices.
