Double Ended Termination Pins

Double-ended termination pins allow construction of X Probe Socketless fixtures with far shorter signal path lengths than conventional wire wrap designs. The shorter path length allows better control of the signal from the tester circuits to the Unit Under Test (UUT). Note: Top test probe is not included with the double-ended termination and should be ordered separately.

Compatible probe series: X31-16, X31-25 and X31-40
