Mill-Max's 0919 spring pin has a recommended working travel range of 0.030” (0.762 mm) to 0.100” (2.54 mm) and a maximum mechanical travel of 0.118” (3 mm), the greatest in their current spring pin lineup. There is a hard stop incorporated to prevent over compression and minimize the risk of damage to the spring. This pin is ideal for applications where greater compliancy is desired. It can compensate for problematic tolerance stack ups in assemblies featuring board-to-board or device-to-board connections. The 0919 allows a greater range of movement between mating components, providing stable connectivity in assemblies subject to motion, such as mobile devices and lightweight devices that often use more flexible housings and materials. When compressed to mid-stroke, it still allows for 0.040” (1.02 mm) additional travel while remaining in the recommended working range. Because the 0919 has more stroke capability, it provides higher forces at its recommended working travel than similar spring pins of this scale. This may be desirable to a designer seeking to sustain reliable contact during cycles of high shock and vibration. The 0919 exhibits an average 85 gram force at mid-stroke with the ability to achieve 127 grams at the top of the recommended travel.

The 0919 is also available packaged in single and double row strips on 0.100” (2.54 mm) centers. The single row series part number is 837-22-0XX-30-001101 and the double row series part number is 839-22-0XX-30-001101. Gold-plated brass components and stainless steel springs ensure the highest reliability, corrosion resistance, and durability. The spring-loaded plunger is suitable for mating with gold-plated PCB pads or Mill-Max target pins and connectors.
