Zebra® Carbon Connectors
Additional options for Zebra® Carbon Connectors are available Here.
FUJIPOLY connectors (see figure 1) have alternating layers ZEBRA® of conductive carbon-filled and non-conductive silicone rubber. They make reliable connections by being deflected between contacting surfaces. ZEBRA® connectors are used for connecting any LCD from small displays for watches to large area displays for instruments. Table A shows the different types of ZEBRA® connectors available. Table C shows performance characteristics.
Figure 1 shows the three dimensions of the ZEBRA® connector. When ordering, the three dimensions should be specified within the limits shown in table B.
For best overall performance, ZEBRA® connectors must be ordered and used with a ratio of H/W equal to or greater than 1.5.

ZEBRA® Connector Dimensions
Figure 2 shows the three dimensions of the ZEBRA® connector. When ordering, the three dimensions should be specified within the limits shown in Table B. For best overall performance, ZEBRA® connectors must be ordered and used with a ratio of H/W equal to or greater than 1.5. 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.

ABLE D *The tolerance of W1 is equal to the sum of the tolerances of W.
Nominal Resistance Calculation
To calculate the resistance of the ZEBRA® connector use the following formulas:
Where:
Cw = Contact pad width in inches
H = ZEBRA® connector height in inches
W = ZEBRA® connector width in inches
Metric:
| R = | 60 x H |
| Ew x W |
Inches:
| R = | 2.37 x H |
| Ew x W |
Where:
R = Resistance (Ω)
Ew = Electrode Pad width (mm or inches)
W = Connector width (mm or inches)
H = Connector height (mm or inches)
Metric:
F(N) = [(9 x D x W1 xL) + {2.2 x D x (W-W1) x L}] x 9.8 x 10-3
Inches:
F(N) = [(5806 x D x W1 x L) + {1419 x D x (W-W1) x L}] x 9.8 x 10-3
Nominal Force Deflection Plain ZEBRA® or Insulation Barrier Type
ZEBRA® connectors should be deflected 5% to 25% of H. To calculate F-Force for deflection, use the following formula:
Where:
F = Force (N)
| D = | H-H1 x 100% |
| H |
H = Height of connector (mm or inches)
H1 = Deflected height of connector (mm or inches)
W = Width of connector (mm or inches)
W1 = Width of ZEBRA portion (mm or inches)
L = Length of connector (mm or inches)
Metric:
F(N) = 9 x D x W x L x 9.8 x 10-3
Inches:
F(N) = 5806 x D x W x L x 9.8 x 10-3
