Oscilloscope BNC mating cycle ratings ?
nurbster:
Hi forum. I recently purchased a USB scope ( PicoScope 4444 ) which utilizes D-sub instead of BNC connectors. I inquired with manufacturer if they could provide me with contact type ( i.e. machined or stamp & formed ), plating and mating cycle rating information for the D-sub connector as used in this model. Their answer was the information was "proprietary" although I think they really meant confidential as I don't think there can be anything proprietary about a right-angle surface mount D-sub. Do oscilloscope manufacturers typically publish such data or are connector manufacturers known such that rating information can be obtained ? Can anybody speak to typical ratings of BNC connectors used in oscilloscopes ?
Thank you.

What do You mean?
Your scope is low bandwith and high imput impedance device
So any connector will be fine

Just one example for an Amphenol part says 500 mating cycles:

Another exmple, Cinch Vitelec, also states 500 cycles:

Is that what you're looking for?

That's actually surprisingly little.

Thanks for replies. Ratings are typically much lower than realized cycles. A rating of 500 does suprise me though as I was thinking BNC connectors as used on scopes would be minimum rating of 1000 and more likely 3000.
