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.
