Packaging
Conscious of the wide variety of applications, contact packaging has been considered for small series (bulk packaging) and high volume
production (reeled contacts):
• 50 pieces bulk packing
(standard)
• 1000 pieces bulk packing
• 3000 pieces reeled stamped
& formed contacts
• 5000 pieces reeled machined

First Mate Last Break contacts should
be chosen only if the cavity is not
marked with the earth symbol. For
cavities marked with the earth symbol,
standard contacts will fulfill the same
role as a first mate, last break contact
used in a standard cavity.

Coaxial contacts
Coaxial contact range
We provide 2 types of coaxial contacts suitable for 50 or 75Ω, coaxial cable or twisted pair cable.
Monocrimp coaxial contact
• The monocrimp one-piece coaxial contacts offer high reliability plus
the economic advantage of a 95% reduction in installation time over
conventional assembly methods.
• This economy is achieved by simultaneously crimping both the inner
conductor and outer braid or drain wire.
Multipiece crimp coaxial contact
• The inner conductor and outer braid is crimped individually.
• The thermoplastic insulating bushing in the outer body is designed
to accept and permanently retain the inner contact.
• An outer ferrule is used to connect the braid to the outer contact
and provide cable support to ensure against bending and vibration.
Suitable for Coaxial cable or Twisted cable
Contacts
• For jacket diameter from 1.78 to 3.05mm
Inner conductor up to 2.44mm diameter
• For jacket diameter from 0.64 to 1.45mm
Inner conductor from AWG30 to AWG24
