B Series protective dust cap is a dedicated accessory designed to safeguard unmated push-pull self-locking circular receptacle connectors. When connectors are not in use, the dust cap provides essential protection against dust, dirt, debris, moisture, and other environmental contaminants, helping to prevent contact corrosion, maintain signal integrity, and extend the service life of the connector.
The dust cap features a snap-fit or push-fit structure for quick and easy installation and removal, requiring no tools. It is designed to fit directly over the mating face of the receptacle, creating a protective seal. Available in both metal (chrome-plated brass/aluminum alloy) and engineering plastic (POM/PSU) versions to suit different application requirements and environmental conditions.
Compatible with B Series EGG, PHG, EEG, and other standard receptacle styles. Available in 0B, 1B, 2B, 3B, 4B, and 5B shell sizes to match various connector configurations
