This ProBlox male coax contact works with Belden 1855A. It is for use in the ProBlox receptacle with locknut and is sold in packs of 10. The coaxial contacts for the ProBlox & ProBlox-D system features an all-crimp 3 piece design. These true 75 ohm contacts have excellent electrical performance up to 3 GHz and are ideal for VGA up to uncompressed HD video applications. There are currently two versions available: one for Belden’s miniature 75 ohm serial digital 1855A, 1855P cable (or equivalent), and one for mini hi-res cable. We recommend using our own WV-RGB5P mini hi-res but it does work with many other cables as well. After being terminated to the cable, the female contact inserts into the plug with actuating screw and the male contact inserts into the receptacle with locknut.
