Emboss Tape
Connectors for FFC and FPC
Features––––––––––––––––––––––––
• Compact
Having no complicated cam or slide mechanism, this
connector is small with a mounting height of only 4.4mm and a
width of 3.0mm.
• Double-sided contact
This connector has highly resilient phosphor bronze contacts,
each of which has two independent mating spring members
that ensure continuity even when subjected to severe vibration.
Because each of the contacts simultaneously mates with both
sides of the FFC or FPC, the engineer has greater freedom in
designing his circuitry.
• Simple snap-in action
The FFC or FPC are securely connected by simply inserting
their leads into the connector.
The FM connector, a miniature connector with a
thickness of only 3.0mm, was developed to
connect flexible flat cables (FFC) or flexible
printed circuits (FPC) with a lead pitch of
1.0mm to printed circuit boards. It is ideally
suited for connections inside high-density
equipment or between mechanical units. The
contact is constructed to ensure a stable
connection and high reliability even under
vibration and impact. Connection is easy with a
simple snap-in action.
• Surface mount model (SMT)
This connector is also available in a surface mount
configuration. Its housing is made of heat resistant resin so that
it is not adversely affected during reflow soldering. Because of
its tiny size and ability to be surface mounted, this connector
meets the demand for high-density mounting of components
inside electronic products.
