2mm-Pitch Thru-Hole Spring Loaded Connectors Mill-Max 2mm-Pitch Thru-Hole Spring Loaded Connectors combine durability and space-saving features. These connectors offer spring pins with a working travel of 0.0275' (0.7mm) and a maximum travel of 0.055' (1.4mm). The initial uncompressed height of these connectors is 0.295' (7.5mm). The series features a solder tail diameter of 0.022' (0.56mm) and a plunger diameter of 0.032' (0.81mm), allowing adequate space for laying out the PCB holes, pads, and traces on both the solder and mating sides of the connectors. Mill-Max 2mm-Pitch Thru-Hole Spring Loaded Connectors maintain the quality and reliability of current Mill-Max spring-pin connectors by utilizing the same precision-machined components and internal spring components.
