D-Sub interfaces with a firm screw locking between connector hood and counter-connector are indispensable for all applications being exposed to e.g. mechanical stress (vibration, traction, bending) or significant temperature variations, but which are nevertheless supposed to provide reliable locking, free from clearance.
Hence, a screw-locked interface does not only ensure a reliable electrical contacting between the connectors. In combination with a full metal hood they also improve the ground contact and thereby the EMC of the interconnection.
Furthermore, the screw connections have to allow a quick and simple assembly; they should not corrode under adverse environmental conditions and should be easily un- and re-tightened even after a longer period of installation.
As a specialist for EMI / RFI shielding interconnection systems Inotec electronics offers the widest product range of full metal hoods for D-Sub connectors with its series MS, MSX, MSB and MSBS.
