Mill-Max - Spring-Loaded Contacts & Connectors

Mill-Max is proud to announce
a new addition to its spring-loaded pin selection with the introduction of the
0919-0-15-20-89-14-11-0.  This new
offering has a maximum stroke of 3 mm (.118”) with an initial height of .379”
(9,63 mm).  It is designed for SMT
termination and can be used at a minimum spacing of .100” (2,54 mm). 

 

The 0919 spring pin has a
recommended working travel range of .030” (0,762 mm) to .100” (2,54 mm) and a
maximum mechanical travel of .118” (3 mm), the greatest in our 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 light weight devices
that often use more flexible housings and materials.  When compressed to mid-stroke, it still
allows for .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 .100” (2,54 mm) 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 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.
