Pace Intelliheat Pinout for 6 to 8 pin adaptor

[Phil Smith]

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

Yes 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.

Thank you, Phil, good info to keep on hand.
Re: drawing, Americans will think the date is December 02, 2024!

Hah, back to the future!
Sometimes I indicate a month as three letter word to eliminate any concerns around the globe e.g. 12-FEB-2024.

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!

That's what I usually do as well when saving files on the drive - so much easier to track them using that YYYY-MM-DD format

PS. I've updated the date on the drawing, I hope now it is clear

Who cares what uninformed people do? Regardless, I was mostly responding to your calling the pinout “illogical” — it’s not illogical, and I showed you why.

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.

Thank you for additional information, helius. Funny enough, everything mates perfectly in my case.
Regarding silver/gold combination, as long as you dont leave them mated for a long period of time I reckon they'll be fine, especially considering the fact it is not a production line, and just an one off for personal use.

Yes, the Pace uses all plastic connectors. As Asis mentioned above, they have -951 suffix.

The plug on my SX-90 has silver contacts, not gold.

On the ST 75 station I use it on, I can’t conclusively tell whether the handpiece socket (which is a custom snap-in panel mounted, PCB-terminated jack) uses gold or silver contacts; I can’t get a good enough look to know whether I’m looking at the exposed cut edges of whatever mystery metal the contacts are made of (they don’t state it anywhere, so let’s assume it’s brass or phosphor bronze), or the actual plating. I’m leaning more towards them being gold, but I can’t tell for sure. It could also be the slightly warm color of tarnished silver. They don’t look as golden as the ones below.

The foot pedal jack on the back, which is a panel-mount jack (from AMP, not Amphenol!) with crimped contacts, definitely uses gold contacts. I don’t have a Pace pedal so I can’t compare the mating plug.

[tooki]

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:
https://www.eevblog.com/forum/reviews/pace-footswitch-connector-for-desoldering-station/

Important:
Renumber the pins of the 8-pin connector correctly, per discussion above.

Change “connector (pins)” to “plug (male)” in the connector descriptions. We already know they’re connectors, but what’s important is whether you’re documenting the plug or the jack. (You probably already know this, but just to be clear on typical English terminology, in case you’re not a native speaker: “Plug”=the part on the cable that’s usually more mobile; “jack” or “socket”* =the part on the panel, except when “inline jack” (or “inline socket”)=cable-mounted jack. Plugs and jacks can have male or female, or mixed, contacts.)

Add a note whether the contact arrangements are as viewed from the plug or the jack, and from termination side or mating face. (The C091 catalog, for example, has the layouts numbered with the “view from termination side of male contact insert”. I would standardize on this.)

Not critical, but nice:

Where you list the SX-90, you can note that it’s SX-80/90/100 — they’re electrically identical.

Remove the apostrophe from “connector’s” in the title.
Fix “channal AUX” to “AUX channels”.
Fix “TT65 tweez” to either “TT65 tweezers” or “TT65”. Make the handpiece titles uniform, either listing the function on all of them, or none.




*because “socket” is often used to denote the female contact (e.g. pins and sockets), I prefer to use “jack” or “receptacle” to mean the receiving role of the connector as a whole, and “socket” to refer to the receiving role of the contact. None of this is strict rules, this is just my suggestion for unambiguous terminology.

While you’re absolutely correct about the part numbers and compatibility, I suspect it’s merely a typo on Phil’s part: the photo of the finished cable shows what appears to me to be a T3428.

Well spotted, cheers. I've amended the drawing. Sure thing it is 3428, as I posted earlier in this topic. Just a typo on the drawing. I've attached my mouser order as well, just for reference.

[GLouie]

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.

Great, thank you, Asis

I will add that PACE releases the SX100 Blue connector and one of the PACE MBT360 ports supports the SensaTemp toolkit.
It is interesting to look at the ThermoDrive technology (TD MBT360) in detail.

Disassembling the SX90 heater:

[tooki]

The switch from black to blue for the heater connector happened during the SX-90 era, so if I understand it correctly:
- SX-80 always has a black heater connector
- SX-90 can have either
- SX-00 always has a blue one

Electrically they’re identical. All of the above exist with either a black SensaTemp connector or blue IntelliHeat connector.

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 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.

Mmm… no. It’s not just that.

Mine has no gold contacts too.

I rebuilt my adapter to a handle switching box with Relais and valves.
Works fine for now. Measured 4° difference before/afterwards which could came from my china solder tip thermometer too.

———————————————
———————————————

2Relais / Handle
Heater and Sensor Pins which are connected to AGND are switched per Handle Socket and for the TD-100 Socket the same heater pin and the middle pin of the connector ( for the thermistor inside handle.)

Hope the right  choice for long time ; I used Reed Relais for the sensors and for others ≥5A Relais with thick gold plating (for low voltage-arc free switching , not with thin gold for long stocking duration). Switching only without power at contacts .
 (TD-100 has its sensor between heater and grounded tip).
The box has a selection switch and a on/off switch which switches the 12V power supply for relays & valves and the power socket where the pace station is plugged with its own switch at station always on . Won’t drill a hole to use the winding from stations control circuit.

To switch between vacuum and pressure tools I use a E valve with 5 openings for hydraulic cylinders.  Vacuum + Filter & pressure connected to OUT A & OUT B // Handles to DRAIN A & DRAIN B // IN left free to soak/drain air so that it not have to go through the unused handle but soaked air always goes through Visifilter . For more as one vac. and one pressure handle additional valves needed between that valve and the handles.

[helius]

I can confirm that all of the tools I have use silver-plated male connectors, including the foot pedal. At least, it looks that way from the front: I don't think the solder-type pins can be extracted. Which leaves me wondering why they selected silver plating: certainly it wasn't to save money on $1000+ soldering stations or $500+ handpieces. Nor are the tools especially high current; I think the SensaTemp tools are all 21 VAC, 51 W, so about 2.5 A maximum per pin. Why didn't they use gold?

[Okto47]

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 ?

Thinking that just because it costs 1000$ at market that they won’t care about +/- 50 cent in production is unfortunately wrong . But that’s not about pace and specially true for  newer designs.

Given that the manufacturer only makes them in silver and gold, no tin option, it’s silver.
