Positronic PCN10624 affects D-sub connectors with signal contacts captivated between two insulator halves, including ODD, DAD, DDA, DDB, DDC, XDA, and XDB Series fixed-contact connectors. (Removable contact connectors are not impacted.)

Affected Part Number(s)
See affected parts list: PCN-10624-Affected-Parts

Change Description
There are four primary changes which make up this design improvement.
1) The current two-piece unbonded insulator will become a one-piece unibody design, unless otherwise noted; and the contact retention mechanism will change from a system captivating
contacts between two molding halves to the concurrently qualified press-in contact system.
2) The alignment bar (when used) will be shorter in length than the existing version.
3) Right angle PWB tail contacts (where applicable) will have a larger bend radius and will continue to conform to all requirements.
4) Solder cup contact termination lengthened.

For full details please refer to the following PCN: PCN-10624

Positronic have issued a Product Change Notification PCN-10645.

PCN Title: Change From Hexavalent to Trivalent Chromium On All Zinc-plated Products

Implementation Date:  11 December 2024

Change Description
1) The supplementary seal on zinc plate will change from hexavalent chromium (ASTM B 633
Type 2) to trivalent chromium (ASTM B 633 Type 5).
Reason for Change
1) Positronic is transitioning from hexavalent chromium to trivalent chromium to improve efficiency.
2) By changing to trivalent chromium, Positronic can remove hexavalent chromium from the
facility.

Increased Stocks

We have increased our stocks of the RJ45 Hermetic Feedthroughs due to the demand over recent months.

If you require next day delivery on RJ45 Feedthroughs, we should be able to facilitate this for you (subject to the time the order is placed, etc).

Hermetic RJ45 jack to RJ45 jack in an SS housing with 1-14 UN X .95 thread.

Supplied with Viton o-ring & SS jam nut.

RJ45 Hermetic Seal – Testing

100% of parts are checked for quality, including dimensional inspection, visual workmanship, leak tested for a <1X10^-7 STD-CC/SEC leak rate or better, electrical hipot 100 VDC 100 MOhms, & continuity testing.

If you require a quotation or further information, please contact us.

D-Subminiature feedthroughs for SPACE or INDUSTRIAL vacuum applications.

Both sides of the hermetic d-sub feedthrough contain four threaded mounting holes, an o-ring groove and fixed female jack screws. These features allow either side of the connector to be mounted toward the vacuum, giving the customer the ultimate in flexibility.

All connectors are 100 % leak tested after fabrication.  All d-sub hermetic feedthrough connectors utilize precision machined contacts for strength and durability. The materials and finishes, as well as the technical characteristics of the d-sub feedthrough connectors conform to MIL-DTL-24308, Goddard and the SPACE-D32 specifications.

Hermetic D-Sub Feedthroughs – Standard Density

With normal density insulators 9, 15, 25, 37, and 50 contacts (20 awg), we stock as standard, Male/Female d-sub feedthroughs.  We do offer both Male/Male and Female/Female d-sub feedthrough options although these will usually carry a slightly longer lead time.

For further information on our standard density hermetic d-sub feedthroughs, please find the following link:

Hermetic standard density d-sub feedthrough

High Density Hermetic D-Sub Feedthrough Connectors

We supply high density insulators: 15, 26, 44, 62, 78 and 104 contacts (22 awg). The feedthroughs are Male/Female as standard.  The high density feedthroughs are generally found from stock at Jacarem in the smaller sizes.  The larger sizes of 78 and 104 tend to be on a lead time.

For further specifications and drawings, please refer to the following links:

Hermetic high density d-sub feedthrough

Mixed Combination D-Sub Feedthrough Connectors

We can also supply mixed contact combinations of d-sub feedthroughs. You can utilise power, coaxial or signal contacts or a mixed combination of these contacts all within a Male/Female feedthrough.

Thermocouple contact options are also available in standard density feedthroughs.  If you would like further information on these options, please contact us.

Flanges with d-sub feedthroughs

If you have a requirement for a custom flange with d-sub feedthroughs, please contact us for further information.

MIL-C-26482 UHV Feedthroughs are available with a commercial bayonet style connection on the air side and a threaded connection on the vacuum side, compatible with MIL-C-26482 standard.  Available with 10, 19, 26 or 32 pins. 3, 6 and 41 pin options available upon request and subject to moqs.

These Ultra High Vacuum Feedthrough connectors are highly resistant to mechanical and thermal shocks.  The working temperature is -40ºC to +250ºC and the leak rate is <5×10-10 mbar I/s He.

We can offer connectors to fit both the air side and vacuum side.

If you have MIL-C-26482 UHV Feedthrough requirements and you would like further information or technical assistance, please contact our sales team at: [email protected] or phone them on: 01494 791336

Our Spaceflight D-sub connectors are qualified to the Goddard Space Flight Centre S-311 and MIL-DTL-24308 Class M specifications.  The spaceflight d-sub connectors are also suitable for use in any application requiring high performance, non-outgassing and low magnetic characteristics.

The space flight connectors are available in standard density and feature fixed or removable contacts and -55°C to 125°C operating temperature. Five connector variants including 9, 15, 25, 37 and 50 pin versions and termination options of wire crimp or solder and straight or right angle PCB mount.

There are high density space flight connectors available with removable or fixed size 22 contacts.  There are six connector variants from 15 through to 104 contacts and these come with crimp, solder, straight and right angle contact terminations.

We also offer the combination space flight d-sub connectors in standard and high density. 

We offer gender changers from Positronic too that can be used with all of the above space connectors.

Space connectors are utilized within the electronic equipment in spacecraft or satellite applications.  Space connectors can’t just be small and lightweight, they have to be extremely reliable as well and they must be able to withstand severe environmental conditions like shock, extreme temperatures and vibration.  The D-Sub connectors have to meet stringent testing for outgassing and residual magnetism to be suitable for use in space applications. Outgassing and residual magnetism can adversely affect nearby components.  The connectors must be tested and approved by NASA or the European Space Agency (or the space agency of whatever country they will be representing).  Costs to launch a payload into space is directly related to the weight of that payload so lightweight connectors are desirable.

Our technical team will be able to assist you with your space qualified d-sub connector requirements.  Please e-mail [email protected] or phone 01494 791336 for further information or to request a visit to discuss your application.

The PEEK D sub connector is a great addition to our range with a Vacuum range of 1×10-10 mbar. Available in 9, 15, 25, 37 and 50 pin. To view the PEEK D-Sub page please click here. To view the full range of Hermetic Connectors and Vacuum Feedthrough Connectors, please click here.

Photoelectric sensors with BlueLight technology – offer greater detection efficiency than conventional red light proximity sensors when detecting dark or transparent objects. Sensors with BlueLight technology therefore prove a cost-efficient alternative to standard red light photoelectric sensors. For example, in the packaging industry, plastics industry, automotive industry, solar industry (wafers), beverage industry orin special purpose machine construction or laboratory automation. These new sensors with BlueLight technology enable optimum detection in even more applications: reliable detection of reflective surfaces even at wide angles, e.g. varnished wooden surfaces, coated metal and painted plastic parts detection of transparent objects without use of a reflector, e.g. film, Petri dishes and cannulae detection of very dark objects, e.g. solar wafers, foam and plastic.
