EMI/RFI/ESD-protected cable connector housing

May 2002 Enclosures, Cabling & Connectors

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 comply with high ESD requirements and provide shielding against EMI/RFI.

The connector housing and knurled screw heads are made of high performance plastic and satisfy IEC 801-2 requirements. Operating temperature range is -65 to 185°C. To improve shielding, two shielding plates are riveted to the housing half-shells. The shielding plates have a special design 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 metallised housings 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 makes a major contribution to this very high shielding level. The strain relief also connects the cable's braided shield to the shielding plates (cables up to 11 mm diameter may be used).

Assembly is fast by means of snap latches on the two half-shells. Fixing screw/s prevent the half-shells from separating. Four housings in sizes 9, 15, 25, and 37 pins are available.
