Crimp
RF
CONNECTOR
Disconnectable Crimp style connectors
Features ––––––––––––––––––––––––
• Highly reliable, yet low in cost
Our original double-leaf spring construction withstands the
stresses caused by repeated insertions and withdrawals and
ensures reliable contact performance. Depending on the
application, the socket contacts and header posts can be
selectively gold-plated or fully tin-plated to minimize costs.
2.54mm
pitch
• Space-saving, high-density design
The 2.54mm pitch contacts are arranged in two rows. The
mated connectors can be placed side by side or end to end
without a loss in pitch. This facilitates space-saving, high-
density circuit designs.
• Easy connection
A slight force is all that is required for contact insertion because
the housing has resilient lances. Furthermore, the positions of
the contacts in the housing can be visually checked. This
The RF connector was developed as a
highly reliable, low-cost, crimp style
connector for connecting wires to printed
circuit boards. Well suited for internal
connections in office automation
equipment, such as personal computers,
office computers and their peripheral
devices.
facilitates insertion of the contacts in the housing.
• It can be cut to any length to provide a header
with any number of circuits
Notches are provided on the insulator that allow it to be cut to
any length without using special tools.
