Perhaps it's actually an SOT346 package, nearly identical, but have a look at this: https://assets.nexperia.com/documents/data-sheet/PZM_N_SERIES.pdf

Just search for "101" and it'll pull up PZM10NB1

Hmm, a candidate, but it would be pretty dumb to be using a 10V zener as a series polarity protection diode! :o

Unless they had some kind of mix-up during board assembly and the wrong (but still semi-functional) part got placed...

Any chance of a good photo?

I know what these are but I don't know what they're called.

I'm thinking of making some high-ish voltage test cables but can't find (just) plugs and think it would help if I knew what names they go by.  Thanks.

UPDATE: Thanks Tautech, especially for the retractable aspect. A little searching on "shielded" and it seems "Retractable Sheath Banana Plug" makes a good search.

Shielded banana plugs.
Some have retractable shields and you'll find them more useful to use in a wider range of equipment.

Hi! I'm new on the forum and looking for advice as to what this type of connector is called - pen included for scale.
It's gold plated and connects the DC motor, tachometer and resolver to the internal wire harness of an industrial robot arm. Both connectors are 30mm wide. Cables attaches to the other side of the pins via simple solder cups.
Looking to replace the electronics in the robot but I want to preserve as much of the original equipment as possible, to enable a future "proper" restoration using the old hardware.
Thankful for any replies :)

Looks like there may be a brand or identifier molded under the label marked "12" - if you could lift the label and have a look, that could help out. What brand motor and what brand robot?

Duh, of course!
It's a Souriau connector. They don't seem to make them anymore - they got a similar snap connector though. Guess I'll have to replace it.
The robot in an old ABB/ASEA IRB6.

Thanks for the help!

Hello,

I'm a proud owner of a JBC HD-2B soldering station.



This station comes with the T470 handles and they are using the C470 tips.
Those C470 tips are nice, but if you want to do some finer work, a T245 with C245 tips would be much better.

Unfortunately, the T245/C245 is not compatible with the HD-2B. Except, if you
put a 60 Ohm resistor in the +Ub path when using a T245/C245.
I have found this in the German "mikrocontroller.net" forum:

https://www.mikrocontroller.net/topic/408786#4791503

I'd like to build a switchbox, where I can switch between the T470 and T245
and for this I need to know, what the connectors are.

The HD-2B comes with a cable, which connects the power supply to the stand for the T470.
The cable has the item number 0011283 and is looking like this:



Does anybody exactly know, what the connectors are?

Thank you for your help.

Have you opened up one of the connectors to see if there's a brand or part number inside the shell?

These were made between mid '80s and late '90s.
I know what these are but can anyone tell me who the manufacturer with the circled "T" symbol is?

I have these really old Centralabs pots.  I know I can measure them, but I was wondering if there's datasheets for these, or if you can determine their values and taper types from the markings?

I didn't spot an actual datasheet, but you might find this useful:
https://www.americanradiohistory.com/hd2/IDX-Consumer/Archive-Radio-Electronics-IDX/IDX/50s/1953/Radio-Electronics-1953-07-OCR-Page-0075.pdf

So if that used pot is servicable,  I'd say that it is a 50K linear.

Why didn't they just stamp THAT on the part  :-//

This 5-pin, SIL IC is marked M5293. It should be regulating the -30-ish-V cathode voltage of a vacuum fluorescent display in an old Sony CDP-S41 CD player. 
But it isn't. An adjacent electrolytic cap leaked and messed up the PCB all around this area. I don't know whether this circuitry is dead, or just not being told to turn on.

When  I google M5293 I just get a bunch of zener diode data sheets. Maybe it's a Sony proprietary part?

I don't suppose anyone would have a data sheet?

Looks like a resistor network to me.

The impossible often has a kind of integrity which the merely improbable lacks.

Brilliant! That's it, pins match, thanks so much. I knew someone would have better google-foo than me.

No worries, I just googled "resistor network M5293" and amzingly it came up despite not being an RN.  :o

How good is your SMD-Codes list? I searched the interweb with little luck. I have a 3 pin device that has what is probably a SOT-23 footprint with a code that reads:

 [ .1H:P: ]

My SMD-codes list has "1Hp" which links to a BC847 npn bipolar. Sadly the device i have does not diode-junction check using my DMM as an npn but a pnp.

Any suggestions appreciated.

Possibly a BC857 (PNP equiv) though it would be marked 3HP?

I finally plugged the 1H.p into my Atlas Peak DCA Pro. Previous diode mode DVM testings began me (excitedly) to think it might be a J-FET. The Peak however confirmed it as boring olde npn. My next move is to hunt down a move reliable source of SMD semiconductor codes.
