Powerful D-subs from In2Connect

D-sub connectors were arguably the first and most widely established in/out (I/O) interface connector, according to officials at In2Connect UK Ltd., based in Ropley, Hampshire. The connectors are so-called because of their trapezoidal (vaguely “D” shaped) shell which provides mechanical protection, shielding and built-in polarization when mating male to female, whether cable-end or panel mounted. They’re still amazingly popular in control and instrumentation, audio, communications and I/O from printed circuit board applications, said company officials.

In2Connect’s mixed layout combination d-sub connectors offer the ability to integrate signal contacts, 50 and 75 Ohm coax, up to 40 A and high-voltage contacts in a standard d-sub shell.

Within the standard range of combo d-subs are versions enabling 2, 3, 5 or 8 x 10 A, 20 A, 30 A or 40 A solder cup, straight or right angled PCB contacts, or HV contacts to be used on their own, without signal contacts. These combination connectors all feature the polarized shielding d-shell to prevent mis-mating; high density space saving packaging, and diverse mounting options. For example the 8 x 40 A contacts sit in a shell size 4 which is the normal 37 way d-sub footprint.

In addition, in line with most of its offerings, IP67 waterproof power versions are available, both front and rear panel mounting. With this water resistant d-sub system, the back-potted and O-ring mounted panel connectors ensure full IP67 conformity whether mated or unmated and can be further protected by an end cap when unmated. The mating d-sub cable end connector can have a waterproof hood. This has a compression ring to stop the ingress of water via the cable entry point at the rear and a sealing skirt at the connector interface. The cable-end connection will not itself meet IP67 when unmated unless a waterproof cap is fitted. Once mated, then the total d-sub connection interface, not just the panel mount d-sub connector will conform to IP67.
