Pace Intelliheat Pinout for 6 to 8 pin adaptor

[Okto47]

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.

[Phil Smith]

I would like to know as well! 
Should not be that hard to DIY one, if you know pinouts and are able to source those DIN connectors..

[Okto47]

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 B
With 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 pin  Will see when it’s here.

Wow! Thank you Okto47 very 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 hah 
But 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

What's the part number of the adaptor? Thanks.

Phil was faster

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.

[Okto47]

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.

Page 20 of the attached manual lists test procedures and expected values for a number of SensaTemp handpieces.

I ohmed my SX-70 Sensatemp desoldering handpiece. It appears the button shorts pin 1 to pin 3 to run the motor. Pin 3 is a sensor return, going to AGND. So tip/earth ground, pin 4, is separate.

[Phil Smith]

Thanks everyone for your input
I'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%3D
6 pin receptacle:
https://www.mouser.co.uk/ProductDetail/Amphenol-Tuchel/T-3428-501?qs=JkAbnbMxW%252BvDPY6FFDZ8tA%3D%3D

One 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?

[tooki]

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.

[Phil Smith]

Lovely, thank you!

I've put em to my basket. I got several parts for my projects I would like to order from Mouser as well, so don't need to pay 15 quid for shipping just for that cable from a local Pace dealer.. And wait for 6-8 weeks!

[GLouie]

Sounds good! Perhaps someone will now make a corrected diagram and parts list for making the adapter - I am too lazy as I don't need one yet!

[Phil Smith]

Hah, indeed I'll try..    

Mouser order has been placed, now I'm waiting for those connectors to arrive.
Also scored nice ST-115 ItelliHeat power supply on ebay to mate with my sensatemp handpieces.

[Phil Smith]

I've opened my ST115 unit and measured continuity to find heater and sensor returns.
See results below (thanks Okto47 for original picture, I hope you dont mind me adding stuff on top of it ):

Looks like now we have everything to complete wiring diagram of that adapter

[Phil Smith]

Hi y'all,
I've drawn first more or less detailed wiring diagram of the adapter. Untested yet..

If you spot any discrepancies - please let me know..
Wire gauges I took from what I've got on hands in the moment - 18 AWG for heater, and 22AWG - for everything else.

[GLouie]

Nice, thanks for the work, Phil. I'm all Sensatemp now, but who knows what the future may bring.

You should put a title, date, and name on the final document after testing.

Hi,

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

Sure thing, thank you!

Oh, that's a great cheat sheet, cheers! Good to have everything in one topic.


Regarding my progress, I've made one cable as per my original drawing and then disassembled and amended it little bit - all wires now are 22 AWG (because in original Pace Sensatemp handpieces they are all the same as well), and made it 50mm shorter. Now it looks like a bought one

Revised 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.

[Phil Smith]

The drawing is revised as well. Enjoy!

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.

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!
