Description

Description

In2Connect stock a wide range of machined pin ‘D’ subminiature connectors: plugs, sockets, hoods and accessories from 9 to 50 way. Flame retardant glass filled polyester GF insulators and gold over nickel plated machined contacts are housed in zinc or tin plated steel shells. D-sub plugs can have dimpled shells to ensure good conductivity for EMI/RFI shielding.

Because of their machined, circular cross-section, turned contacts have a lower electrical transfer resistance than their stamped and formed counterparts and provide a stronger, more durable interfacing solution. This means that male and female d-sub connectors fit more precisely together and give a more reliable connection with more tolerance to vibration.

The part-numbering system used on many d-sub connectors is based on the American topology using “D” as the prefix for the whole series, followed by a letter denoting the shell size (A=15 pin, B=25 pin, C=37 pin, D=50 pin, E=9 pin), followed by the actual number of pins, followed by the gender (P=plug, S=socket). For example, DB25S denotes a D-sub with a 25 position shell size and a 25 position female contact configuration. The Conec range from In2Connect adopts an alpha/numeric part numbering system, so for example DB25S would be a Conec 164A10039X ~ for further info please download the respective data sheets.

There are two differing d-sub PC Board between row “footprints”, the American MIL-C, where the contacts are spaced approximately 0.108 inches (2.74/2.77mm) apart with the rows spaced 0.112 inches (2.84 mm) apart and the European which is generally 2.74/2.77mm (0.108″) between contacts and 2.54mm between rows. This is a very important consideration to PCB design engineers and is easily picked up from the PDF files we publish from Conec and our In2Connect own-brand etc. Please call us if you are in any doubt about PCB footprints. Because the dimensions of d-sub connectors are generally in accordance with IEC 60807-2 (was DIN 41652), BS9523 F0018, MIL-C-24308 and satisfy IEC Recommendation 48B; they are compatible and interchangeable across manufacturers. The dsub standard D connector range is vast but In2Connect generally has the solution.

Applications

Applications

Historically the widest application of D-subs has been in RS 232 serial communications. RS-232 devices originally used the DB25 25-pin D-sub, but for many applications the less common signals were omitted, allowing a DE9 D-sub to be used. Female connectors are normally fitted to the device and male connectors at the cable , but PCs often tend to have male connectors at the device, while modems may have female connectors.

In2Connect stock product from Conec and others. A choice of many termination styles including crimp are available making this range one of the most versatile:

  • Solder-bucket contacts with cavity for hand-soldering
  • Insulation Displacement contacts (IDC) for use with flat ribon cables
