The 10-040450-28S is a flat sealing gasket specifically designed for use with flange-mounted receptacles of MS Shell Size 28. Its primary feature is providing maximum radio shielding in environments with high receiver sensitivity and low signal strength, without compromising the sealing characteristics of a plain gasket. This shielding gasket has a specified thickness of 0.020 ± 0.004 inches and is configured for a four-hole mounting pattern. It is an essential accessory for ensuring optimal connector performance and signal integrity where both robust sealing and EMI/RFI protection are required.
