Description

Spring-connected mating components with four end options

The 2KDR family combines straight-through spring wire connections with a pluggable mating interface. Each model has one row at 5.08mm pitch and 2–24 poles. The actuator buttons operate the conductor springs; model suffixes identify the end arrangement.
