Zebra® Silver Connectors

FUJIPOLY low resistance ZEBRA® elastomeric connectors are constructed of alternating parallel layers of electrically conductive and non-conductive silicone elastomer. The electrically conductive layer is filled with silver-metal particles.

The composite alternating layers provide reliable electrical connection when placed between two aligned conducting surfaces.

The low resistance ZEBRA® provides a redundant connection with a minimum of two conductive layers recommended per PC contact pad. The connector is available with insulating barrier or silicone supports (See page 6). The connectors are used for connecting electroluminescent (EL) and plasma type displays to PC boards or for connecting hybrid circuits to PC boards, among other applications.

Zebra Construction

Low resistance ZEBRA® connectors are positioned between two aligned surfaces and are mechanically clamped together with a lid or another PC board. The connectors may be free standing or positioned in a retainer depending on packaging profiles and design.

Layers of Silicone
Details show silicone support (left) and insulation barrier (right). Each is available on one or both sides. Configurations may also include support on one side and insulation on the other.


Recommended deflection range is 5-25% of free height. Minimum deflection will vary with packaging applications and should consider overall height, PC board warpage, finish, etc. (Contact Fujipoly Product Application Engineering for assistance.) Design recommendations for solid ZEBRA® over 0.400” deflect 0.050” maximum. Silicone supported over 0.400” deflect 0.060” typical.

Nominal Resistance Calculation

For the purpose of calculating the resistance of silver ZEBRA® connectors and testing them for compliance please use the following formula:

Resistance Calculation

Example: if ZEBRA® is 0.100”/2.54 mm H and 0.030”/0.762mm W, then the maximum resistance on a 0.050”/1.27 mm wide pad will be:
