BNC connector choice for additional probe

Post by Avdr »

Hi, I have recently got hold of a pressure transducer (not the WPS500x), my plan is to terminate the output in a BNC connector to allow it to plug directly into the scoce. However, upon opening up my maplin catalogue there are differing types of BNC with differing impedances, prior to this I hadn't even considered that the plug would have an impedance just on its own, so the crux is which type of bnc do I need?
or should I just terminate in 4mm bannana plugs and use an existing pico test lead? - though this instantly means an extra 10ft of wire to keep out of the way.

Many thanks
Andy

I have now determined that the test leads have 50 ohm impdeance, therefore it would follow that the 50 ohm BNC connector is best suited?
