Spring-loaded pin provides greater compliancy for mobile devices

With an initial height of 0.379
in., the 0919-0-15-20-89-14-11-0 spring-loaded pin has a maximum stroke of 0.118
in. Designed for surface-mounting, the spring-loaded pin has a recommended
working travel range of 0.030 to 0.100 in. and can be used at a minimum spacing
of 0.100 in.

The pin is suited for applications
where greater compliancy is desired. That is, it can compensate for problematic
tolerance stack-ups in assemblies with board-to-board or device-to-board
connections, allowing a greater range of movement between mating components to
provide stable connectivity in assemblies subject to motion, particularly those
that use more flexible housings and materials, such as mobile devices. When
compressed to mid-stroke, the pin still has 0.040-in. 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, which helps to maintain 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 minimum
recommended travel.

The pin has a hard stop
incorporated to prevent over-compression and minimize the risk of damage to the
spring. Gold-plated brass components and stainless steel springs are used to 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.

The pin is also available
packaged in single- (837-22-0XX-30-0011X1) and double-row (839-22-0XX-30-0011X1)
strips on 0.100-in. centers; the strips can be delivered bulk-packaged or on
reel.
