Hi

I would like a true 75Ω BNC 90degree (female to male) Connector

Is this one?

Thanks in advance.

Certainly looks like it.

If what you want is to plug a BNC cable into a BNC socket, but have the cable run parallel to the body of the device instead of straight out, this is what you want. (Or ideally a cable with a 90 degree connector in the first place.)

Thanks for that infocus yes thats what I need it for, not straight out.

Thank you.

I have a sort of flight case/fishing tackle cantilever box that I carry to gigs. It's full of similar adaptors and can be a life saver. There's probably a couple of hundred quid's worth of bits and bobs but you don't need to buy it all at once, just when making up orders.

Tell what I want it for infocus,
Out of my NanoFlash to an SDI cable, less pressure on the SDI cable.

It looks right. There could only be one problem, the characteristic impedance. The picture's not clear enough to see if the central pun is thin or thick, it should be thin, the thick ones are 50 ohm for rf use. Either will do, but the thick pin of nthe 50 ohm version can distort the socket and make it unreliable afterwards.

Hi Alan,
Thanks As long as I'm getting the correct signal to the NF via this connector.
That's what I need really.

Thank you.

Thanks Alan.

I had ordered this a few days ago, It arrived and thought I better check first and see if its the correct one.
I'm looking at it now Alan and the centre pin looks thin but then I don't know what to compare it to regarding a thick pin.

These are a ones in the nanoflash site.

I had a look at the pins on my SDI cable and the 90 degree connector pins look similar, to my untrained eye.
Both tapered at the end coming to a point.

Don't worry, it'll be fine, I reckon it's a thin one.

Tony,

The adaptor that you liked to looks like a 50 ohm type as it appears to have a dielectric sleeve around the female socket pin. The site seems to be more RF than video sales oriented and the only BNC compatible cable they have is RG58 which is 50 ohms, so I assume that the RA adaptor is 50 also.

Agreed, it looks like 50. But it'll still work, there's a long history nof using 50 ohm plugs in 75 ohm sockets, because the fit is tighter. It slightly opens up the socket, meaning that a proper 75 ohm plug will be unreliable, but that's all. Go ahead and use it, it'll be fine.
