A note regarding pin numbering - I took the pattern from physical connectors I got on hands (T 3425 501 and T 3524 501), beware of illogical pin numbering for Intelliheat connector..That is the standard numbering for an 8-pin DIN connector. It's actually quite logical. (Hint: it mates with the 3-pin and 5-pin plugs, too.)
See https://en.wikipedia.org/wiki/DIN_connector#Circular_connectors and in particular https://en.wikipedia.org/wiki/DIN_connector#/media/File:DIN_connector_pinout.svg
Thank you, Phil, good info to keep on hand.

Re: drawing, Americans will think the date is December 02, 2024!That’s why I prefer the YYYY-MM-DD date format: not only is it unambiguous to everyone, it also sorts chronologically when you apply an alphabetic sorting to it!

See https://en.wikipedia.org/wiki/DIN_connector#Circular_connectors and in particular https://en.wikipedia.org/wiki/DIN_connector#/media/File:DIN_connector_pinout.svgYes indeed it is a standard pattern, but judging by all sketches I saw most of people count pins in simple clock/counterclockwise fashion + 8th pin in the centre, that's why I stated to pay attention to the actual numbering

A note regarding pin numbering - I took the pattern from physical connectors I got on hands (T 3425 501 and T 3524 501), beware of illogical pin numbering for Intelliheat connector..The T 3425 will not mate with the SensaTemp tools since it has its collar lock reversed from the correct way. On Pace soldering equipment the male connectors are "locking inside" and the female connectors are "locking outside". So consult the catalog: the correct female locking outside 6-pin cable-mount sockets are T 3428.
Additionally, the Pace tools use gold plated contacts (not silver) and "full plastic" connectors without a metal shield, although this will not prevent mating with other types. I think I would avoid mating gold to silver contacts if I have the option. Keeping all these the same as the stock connectors practically mandates using the crimp connector series, since the full plastic types are not available in gold solder contacts. The proper contacts in bulk packaging (100 piece/bag) are VN 01 015 0046 (2) male, and VN 02 015 0046 (2) female. These will crimp to 22–20 awg wires, like Pace uses on their ST and Intelliheat tools. Older foot pedals may use heavier wire if they were used to switch power directly.

Hi,
I'll try to summarize the topic.
If there are any changes or inaccuracies, please let me know.

This link has a disassembly of the Amphenol connector:

Oh dear, now Phil should've changed the drawing date, or made it REVC after the typo corrections!
Hi,
Used Amphenol Circular Connectors C 091 A/B/D Series terminology.
Connectors can have replaceable contacts, either pins (crimp termination) or sockets.
For this reason, some contacts, in order to save money, may be missing.

Corrected.
If you have any comments, let me know.
Follow-up about the contact materials: on the ST 50 station at work, the socket has unmistakably silver contacts. So I’m gusssing my ST 75 at home must be gold, since it looks so different.
Maybe this is not a coincidence? The ST 75 being a desoldering station, it uses one contact for the switch, which is a low-current logic level signal. I guess in theory gold is better for this?

I guess in theory gold is better for this?I don't think plating material makes any difference for the switch signal on the connector. You may be thinking of an actual switching contact that makes and breaks a circuit, where it's essential for the contact to be "wet" and not blocked by oxide. In fact many of those are silver plated, I think for reasons of arc-breaking and erosion. Silver can also be plated much heavier than gold can economically.
The only real case where choice of connector plating is critical (that I can think of) is when thermoelectric effects need to be considered.
The thermojet tools have even a bit more power .
Gold is not always better , has its downsides at some circumstances .
Is it even silver now or just ordinary tinned ?
