D-sub I/O Connectors from In2Connect

D-sub (d-sub, d sub, dsub, sub d, d subminiature) connectors are the best known In/Out (I/O) interfacing connector type having a trapezoidal (vaguely "D" shaped) shell such that they have an inbuilt polarisation male to female. Steel shells are normally plated with nickel, tin or RoHS compliant Trivalent Chromium zinc although for anti-magnetic applications the base material may also be brass or other suitable metals. Male connectors with tin plated shells are normally "dimpled" to create good electrical continuity with the mating female, thus ensuring EMI/RFI shielding if screened cables have been terminated to the shell. D-subminiature connectors are available in five standard shell sizes: 9, 15, 25, 37 and 50 way. The dimensions of d-subminiature connectors are generally in accordance with DIN 41652, BS9523 F0018 and MIL-C-24308; because of this they are compatible and interchangeable across manufacturers.

The contact pitch or distance between pins in a standard size connector is generally 2.77mm with 2.54mm or 2.84mm between rows dependant upon whether it's a US or European PCB board 'footprint'. D-sub connectors are available with solder bucket, straight PC, right angled PC, IDC, surface mount or wire wrap terminations and can be fitted with a range of board locks, female jackposts, etc. The application will normally dictate the use of either precision screw machined or stamped and formed contacts with gold plating over nickel finish. The circularity of the contacts and the thickness of the gold plating will influence the number of mating cycles achievable. Insulators are generally polyester with UL rated self extinguishing properties. High-density, 15 (VGA), 26, 44, 62 and 78 way are versions which pack more contacts into a standard dsub shell ~ e.g. a 15 way VGA connector has 15 pins in three rows in a standard 9 way dsub shell size.

Combination connectors allow the engineer to accommodate coaxial, high current or high voltage contacts in the same footprint as a signal connector, thus one connector allows a mixture of in/out functions at the equipment interface. In2Connect excel in the provision of double-decker, filtered and IP67 water proofed D sub connectors, as well as a wide range of hoods and connector accessories.

Sadly both 2eUK and Selkom have ceased trading ~ we hope that we can assist their ex customers with equivalent product from ITW McMurdo, Conec and others.
