elastomeric connectors

YL Type Elastomeric connectors

The YL typeelastomeric connectors has conductive ability in the W direction and H direction, and the L direction is insulated.Various shapes such as T-shapes, cross-shapes, trapezoids, etc. can be made according to the needs for the application of point reading pens, touch pens and special structures.

Naming conventions

To ensure that elastomeric connectors are made correctly, the naming conventions are as follows:

Preload relationship and curve

The superior elasticity of elastomeric connectors can effectively avoid the risk of good contact with components due to aging deformation and accidental drop of structural parts during the use of electronic equipment, but with the deformation of structural parts and the change of compression force, the compression ratio and resistance of elastomeric connectors will also change, and it is necessary to fully consider when setting structural parts and elastomeric connectors. As follows:

Spline: YL P0.1 10 × 5 × 2.5mm

Resistance vs. compression ratio

Relationship between pressure force and compression ratio

The calculation of conductive rubber connector resistance can be referenced by the following formula:

R = Resistance value (Ω)
CW = Conductive width (mm)
L = Conductive length (mm)
H = Conductive height (mm)
ρ = volume resistivity (Ω·cm)
The testing process should be maintained > 1% compression ratio to obtain accurate test results


The calculation of the compressive force of a conductive rubber connector can be calculated by reference to the following formula:

F = Compressive force (g)
E = Modulus of elasticity: 4.4 (MPa)
D = Compression ratio D = (H-H1) ÷H
H = Conductive rubber connector height (mm)
W = Conductive rubber connector width (mm)
L = Conductive rubber connector length (mm)
