Standard FPC Connectors - 0.5mm, 1.0mm, 1.25mm PitchTE Connectivity
Multiple Centerlines
Basic Information
Centerline can be measured many different ways; however, in general, it is simply the spacing between the center of
one contact and the center of its neighboring contact.
Here you can see an example of the centerline spacing on an FPC connector and the centerline spacing on a fl exible
printed circuit cable.

Stuffer Actuator (Plunger Style)
Many of our larger pitch ZIF-style FPC connectors use a stuffer-type actuator [See Below]. Stuffer actuators use a
slightly different method to secure an FPC cable into the connector than the fl ip-lock versions [For flip-lock versions,
see Fine Pitch FPC Connector Quick Reference Guide, document number 8-1773459-2].
Stuffer actuators are typically used in vertical applications for ease of use: however right angle versions are also available.
ZIF and non-ZIF
Step One:
Starting State
Step Four:
The FPC is now securely mated with
the connector
Step Three:
Insert the FPC into the connector &
slide stuffer backward to close
Step Two:
Slide Stuffer forward to open
Upper (Top) Contact vs Lower (Bottom) Contact
Many of our fi ne pitch FPC products are available in both Upper (top) or Lower (bottom) contact versions. This attribute
simply represents which portion of the contact the fl exible printed circuit interacts with. As you can see from the image
below, the FPC contacts are formed in a “U” shape. Only one prong of that “U” shaped contact interfaces with the fl exible
printed circuit contacts. Choosing the correct contact design is generally based on the orientation of the fl exible printed
circuit as described below.
If the contacts of the
fl exible printed circuit are
facing up (away from the
board) then the upper
contact version is required.
If the contacts of the fl exible
printed circuit are facing
down (towards the board)
then the lower contact
version is required.

ZIF Connectors
・ Use an actuator to secure the fl ex cable
・ Less wear on contacts
・ Increase mating cycle count
・ Provide added retention
・ Better for high vibration environments
Non-ZIF Connectors
・ Use friction to secure the fl ex cable
・ Lower mating cycle count
・ Better for static applications
・ Smaller and lighter weight than equivalent ZIF counterpart
・ Take up less board real-estate
・ Typically less expensive than equivalent ZIF counterpart
