The FM connector, a miniature connector with a
thickness of only 3.0mm (.118"), was developed
to connect flexible flat cables (FFC) or flexible
printed circuits (FPC) with a lead pitch of
1.0mm (.039") 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.
Features–––––––––––––––––––––––
• Compact
Having no complicated cam or slide mechanism, this
connector is very small with a mounting height of only 4.4mm
(.173") and a width of 3.0mm (.118").
• 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.
• 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.
