SCS 4270 Series Connector Covers feature a new unique Conductive Composite material. The material is made intrinsically conductive by uniformly distributing a conductive matrix of fibers during compounding. The covers are permanently volume conductive and free of carbon black particulate. The 4270 Series Covers do not leave black marks and are more suited to clean situations.
4270 Series Connector Covers are noncorrosive and produce no visible corrosion when tested to Federal Test Method 101C using Kovar test plates.
4270 Series Circular Connectors Covers were designed to meet the requirements and intentions of MS90376, and MIL PRF 5501/31A or 32A. Prominent military contractors have qualified these materials to their own specifications and are encouraging their use.
