Machined Pin D-Sub Connector

machined pin d-sub

High Performance D-Sub Connector

Designed for demanding industrial applications, these ITW McMurdo, Conec and In2Connect own brand "Standard" d-sub connectors have precision turned contacts, suitable for a minimum of 500 operations.


In2Connect stock a wide range of machined pin 'D' subminiature connectors: plugs, sockets, hoods and accessories from 9 toMcMurdo Standard d-sub connector 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 uses on many d-sub connectors including In2Connect’s ITW McMurdo range 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 ITW McMurdo, Conec, 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.

Key Features


  • ITW McMurdo 'standard D', Conec and In2Connect own brand turned pin d-subs meet the most demanding requirements.
  • Precision turned contacts. Available in five shell sizes, providing up to 50 contacts.
  • Solder bucket, p.c., 90 degree p.c. and wire wrapping termination styles - to suit all your d type connector applications.
  • D-sub tinned and dimpled shell options - for enhanced electrical continuity and effective EMI/RFI shielding.
  • Wide range of d-sub accessories for greater user flexibility; including threaded insets 4-40 UNC or M3, optional screwlocks and solderable boardlocks fitted to straight and 90 degree p.c. versions - meaning reduced assembly time.

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 ITW McMurdo, 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
  • Crimp and poke home contacts
  • Wire wrap contacts for prototyping.
  • Straight and 90 degree p.c. terminations
  • Surface mount contacts
  • Press-fit contact tails

....but if not in stock then a minimum order value may apply.
