PC BOARD MOUNTING CONNECTORS
720 SERIES (CRIMP TYPE CONNECTORS)
s
FEATURES
The 720 series connectors (crimp connector) are designed
for a wide range of uses, and come in many shapes, two
contact arrangements (one and two rows), and various pin
types. The 720 series headers can be mated with 700 and
740 series sockets, and are lockable when a special cover
is used. Female contacts are secured in the housing by a
unique internal spring structure. High-pressure contacts
are also available which prevent accidental disconnection in
applications that use only a few contacts.
For W and S type headers, insulation molds can be cut to
the necessary size.
