Mill-Max introduces spring-loaded board connector pin for high shock and vibration


Mill-Max Manufacturing Co. in Oyster Bay, N.Y., is introducing the 0919-0-15-20-89-14-11-0 spring-loaded board connector pin for aerospace, defense, and other applications that operate in high shock and vibration.

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 light-weight devices that often use more flexible housings and materials.

This new offering has a maximum stroke of 0.118 inches with an initial height of 0.379 inches. It is designed for SMT termination and can be used at a minimum spacing of 0.1 inches.

 The 0919 spring pin has a recommended working travel range of 0.03 inches to 0.1 inches and a maximum mechanical travel of 0.118 inches. There is a hard stop incorporated to prevent over compression and minimize the risk of damage to the spring.

When compressed to mid-stroke, it still allows for 0.04 inches 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 is also available packaged in single- and double-row strips on 0.1-inch centers. The single-row series part number is 837-22-0XX-30-001101 change last three digits to 191 for tape & reel packaging; the double-row series part number is 839-22-0XX-30-001101 change last three digits to 191 for tape & reel packaging.

Gold-plated brass components and stainless steel springs ensure high 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
