Hello,

Recently, I came across an old stim box that works great, but has an output that connects to an odd connector type (see pictures below). I am hoping to order one of these and wire it to a BNC. Any advice is greatly appreciated.

 

PL259 50Ω coax connector for RG-8 coax, or RG-58 w/ adapter insert. They make PL259 to BNC adapters for it.

 

Hello,

You are looking at a PL259 coax connector:

You could look for an adapter to BNC:

Thank you so much! Just ordered one on amazon

 

Also from what I can see of the markings, it's an Amphenol brand. You should find PL259 marked near that.
