The Erni KSG200 cable connector housing is intended for use with the TMC series, D-Sub connectors to DIN 41612, MIL-C-24308 and IEC 807-3. It was designed to fulfil the high ESD requirements and to provide shielding against EMI/RFI in accordance with new EMC laws. ESD protection is essential for high performance data transfer at high frequencies.
To ensure optimum ESD protection, the cable connector housing and the knurled screw heads are made of high performance plastic and satisfy the requirements of IEC 801-2. Operating temperature range is -65 to 185°C. To improve EMI/RFI shielding, two shielding plates are riveted to the half-shells of the housing. The shielding plates have a special design conceived after extensive testing which allows a very high level of shield attenuation. At 100 MHz more than -66 dB and at 500 MHz better than -55 dB. Comparison values for a metallised housing are approximately -55 and -45 dB respectively.

The lamellar indents of the shielding plates at the contact points to the TMC connector and to the strain relief contributes greatly to this very high shielding level. The strain relief also connects the braided shield of the cable to the shielding plates. Cables with a diameter of up to 11 mm may be used.
A further major advantage of the housing is fast and easy assembly by means of snap latches on the two half-shells. Fixing screws prevent the two half-shells from separating (eg if the housing is dropped on the floor). For servicing, the two half-shells can easily be disassembled by removing the screws.

As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
