CONDUCTIVE D-TYPE CONNECTOR COVERS

Conductive D-Type Connector Cover Features:

Conductive Composite

Permanently volume conductive and free of carbon black particulate. The

connector covers do not leave black marks and are more suited to clean

situations. Meets the requirements of NASM5501 31/32.

Noncorrosive

Connector covers are noncorrosive and produce no visible corrosion when

tested to Federal Test Method 101C using Kovar test plates.

Conformability

The material used in the covers was selected for its resilience. Properly

sized, the covers provide a snug, secure fit. This helps keep connectors

clean and prevents the cover from accidentally falling off.

Specifications and procedures subject to change without notice.

“It should be understood that any object, item, material or person could be a source of static

electricity in the work environment. Removal of unnecessary nonconductors, replacing

nonconductive materials with dissipative or conductive materials and grounding all conductors are

the principle methods of controlling static electricity in the workplace, regardless of the activity.” [ESD

Handbook ESD TR20.20; section 2.4 Sources of Static Electricity]
