The decreased stroke (-D) option is available in our .400 [10.16] long stroke probes. The design combines standard .250 [6.35] stroke springs and tubes
with .400 [10.16] stroke plungers. This produces a probe with the same overall length as the .400 [10.16] stroke series probes with a decreased full stroke
of .250 [6.35]. At the .250 [6.35] stroke the springs are fully compressed to solid height preventing further movement.
These probes are typically used where higher spring forces are needed when contacting loaded boards where there is a big difference between the heights of pads and components.
