content: Hello,Anyone got the pinout for the Intelliheat plug ?Or the wiring diagram of their 6 to 8 pin gender bender adaptor or could measure it ?(The adaptor to connect Sensatemp handpieces with black connector to Intelliheat stations with blue connector).Because I can’t find a seller inside EU for it , farnell doesn’t sell it anymore and the US shops I found which ship to EU only offer very expensive shipping options ( >100$ + fees ).Thank you.

content: Yeah no one posts it , found that others asked the same at other forums.And not Easy to get one if not in US.Connector should be Amphenol C 091 BWith crimp contacts (if I remember right).Take care of Bayonet gender and lock pin side , as booth versions exist , pin male / bayonet male , and pin male / bayonet female .I could share what I have measured for me and works for me with (heatwise) TD-100 and (Sensatemp) THERMOJET. Haven’t verified it with other handpieces as I’m still waiting for them.!!!Maybe it’s wrong and work only with that thermojet!!!First picture is the Intelliheat Station and how I have connected the handpieces and which resistance.!! PIN numbering is not the original one from connector datasheet !!And I drawed Thermistors everywhere but it’s of course not , inside tip a thermocouple…..(TD-100 , easy to open handpiece to see which side the thermistor is. Or measure if temperature is stable , ~2600Ω and only +4Ω to wrong pin ).At my thermojet I can’t measure if at Sensatemp connector switch is between 1 and 3 or 1 and 6 as it was a demolished handpiece and I already mounted a 8pin connector on it but easy to measure if you have any handpiece with switch.Doesn’t know about cartridge tweezer , maybe it’s same as TD-100 and heaters in parallel with full wave and each with a diode to get a half , or maybe second heater is the middle pinWill see when it’s here.

content: Wow! Thank youOkto47very much for this in depth post!I've got a quote today from my local UK supplier, they ask £33+20%VAT+£15 shipping (total of 54.6 pounds, or around 70 US bucks) - quite a price for a one short cable!.. On top of that it is 6-8 weeks lead time hahBut those Amphenol connectors cost something like 7-8 quid a pop on Farner or Mouser +20% VAT + shipping. So It is quite tempting to just order it from Pace

content: I do not know the exact answer, as I only have MBT250 Sensatemp devices. However, the manual for the Thermo-tweez TT-65 does have a wiring diagram, indicating that pin 6 and 3 are for the sensor. TT-65 is not switched, so pin 1 is not used.I have a TJ-70, I will see if I can check the switch pins.

content: That would be great , then there should be all for that adaptor.Yeah , thought too that TT65 tweezer has sensor at pin 3 & 6 , same as my thermojet.I meant the cartridge tweezer MT-100 - not Sensatemp. (Intelliheat 8pin station or heat/temp-wise 4pin station).My TD-100 was a 4pin too, now it’s 8 pin.Will see how that tweezer works when it’s here.Got booth very cheap as there is not such a big interest for used 4pin heatwise handles like it is with 6pin Sensatemp or 8pin Intelliheat handles.So great that they work at Intelliheat if changing plug or with diy adaptor.

content: Thanks everyone for your inputI've searched Mouser and come up with part numbers for 2x connectors required.8 pin plug:https://www.mouser.co.uk/ProductDetail/Amphenol-Tuchel/T-3524-501?qs=wN1CWlV6XgZWamoI1fzq3A%3D%3D6 pin receptacle:https://www.mouser.co.uk/ProductDetail/Amphenol-Tuchel/T-3428-501?qs=JkAbnbMxW%252BvDPY6FFDZ8tA%3D%3DOne thing I'm wondering, in the description it states "Termination Style: Crimp / Solder ". Does it mean they have contacts installed in them or they are just shells and appropriate contacts should be bought separately?

content: Yep, they’re the Amphenol C091B series.Mouser just has the metadata wrong. Both the datasheets and the catalog (all available on the mouser product page) list those part numbers (…-501) as being the tin-plated solder versions. The catalog makes clear that only the crimp versions (…-551) require you to buy contacts separately.

Now it looks like a bought oneRevised drawing will follow.The adapter is tested now with my Sensatemp II TT-65 Tweezers, SX-70 Sodr-X-Tractor and Thermopik connected to Pace ST-115 Intelliheat base station.

content: Quote from: Phil Smith on February 12, 2024, 01:32:27 pmThe 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.

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. AsAsismentioned above, they have -951 suffix.

content: Quote from: helius on February 16, 2024, 02:22:32 amThe 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.

content: Quote from: asis on February 09, 2024, 10:41:52 amImportant: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.

All of the above exist with either a black SensaTemp connector or blue IntelliHeat connector.

content: 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?

content: Quote from: tooki on February 19, 2024, 01:44:49 pmI 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.

Measured 4° difference before/afterwards which could came from my china solder tip thermometer too.——————————————————————————————2Relais / HandleHeater 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.

content: 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?

But that’s not about pace and specially true for newer designs.
