Contacts
Additional Advantages of using Universal Contacts
Universal Contact is an independent SMT contact which provides
an electrical connection between a device and a PCB. The contact
is manufactured as a single piece stamped product, incorporating
pre-load and anti-lift features. The Universal Contact has been
designed to replace traditional interfaces where the contact is
custom designed into the component. It can be used to connect
a number of device components in any direction and configuration using the same interface.
• Qualification time reduction - same contact for many components
• Allows standard interface across applications and platforms
• Freedom to position at an angle - not fixed by mating component

component surface finish and plating type, increased mating
component plating spec = increased mating cycles.)

Range of heights available:
- 1.3mm contact with the minimum pitch of 1.35mm
- 1.8mm contact with the minimum pitch of 1.25mm
- 2.5mm contact the minimum pitch is 1.35mm
- 3.5 & 4.0mm minimum pitch is 1.45mm
•
Solderwell that prevents solder wicking up the
contact
•
“Side wings” protect the active parts of the
contact which prevent contact from
overstressing and potential damage
•
Domed contact point allows good hertz stress and
low contact resistance
•
The X-Y-Z movement allows robust connection
between the contact and component assembly
during shock and vibration
•
Compliant with WEEE and RoHS directives.
