Testing loaded printed circuit boards can be complex when various target heights are present and when you do not want to adjust the socket or termination pin set height.

QA Technology’s long plunger (-L) option in our 0.250 [6.35] stroke series offers a solution to help contact the shorter target, while maintaining the same spring force when the fixture is actuated at the recommended working stroke.

* Note: This option was formerly known as the -D option in our 0.400 stroke series.
