A dust cap is a small cover designed to protect connectors or openings from external elements.
These caps play a vital role in blocking the entry of dust and debris. Available in various materials, shapes, and sizes, they are primarily utilized for safeguarding connectors, ports, or openings in machinery and electronic devices. By shielding connector interfaces and port openings, dust caps effectively prevent the intrusion of harmful particles, thus prolonging the equipment's operational life.
Dust caps are essential in numerous applications and require periodic replacement. Compromised dust caps, whether damaged or soiled, can lead to inadequate protection, risking the integrity of the machinery and electronic devices they are meant to safeguard.
