Help!  

•  Please  contact  Ceramtec  and  see  about  samples  or  order  single  pieces.  Eventual  order  will  be  for  100  of  each  part  needed  (100  PMT  signals).  

•  Should  we  consider  other  parts?  Double  ended?  (More  connectors  =  $$$).  

•  Other  vendors?  •  I  would  like  to  prototype  this  cabling  ASAP.    •  I  am  not  sure  how  to  connect  ground  braid.  Set  screw  to  a  welded  pin?  Leave  floaKng?  Any  advice  from  the  manufacturer?
