Dust Covers
Connector Dust Covers are used to protect the pins of connectors that are exposed when having no cable attached. Dust covers may be produced in either Plastic or Metal. Plastic dust covers are much cheaper than there more expensive metal counter-parts. Metal dust covers may also be made to shield against EMI issues. In addition many styles of metal dust covers also come with an attached chain which may be secured to the chassis. Using the chain insures that the dust cover is not dropped or lost when disconnected for cable attachment. Either metal or plastic dust covers come in almost any connector shape, including D-Sub or circular connectors. Circular caps will press fit on in the case of plastic or screw on in the case of metal types. While D-Sub miniature types will press fit on with either plastic or metal caps, but the metal will also use the locking screws on either side of the D-connector. Environmental Protection Rating.
