An elastomeric connector is a specialized component designed to establish electrical connections between circuits without relying on solder. Unlike traditional methods, elastomeric connectors utilize an elastomeric core housing conductive paths, such as wires, to facilitate seamless electrical contact. This innovative design ensures reliable connectivity while offering flexibility and durability, making elastomeric connectors ideal for a wide range of applications.
When an elastomeric connector is compressed onto a layout of conductors, such as metal contact pads on a PCB, it establishes electrical contact with the conductive pathways. This allows signals to be transmitted from one side of the connector to the other, where it is compressed against a second layout to receive the signals. Essentially, the elastomeric connector serves as a bridge, enabling the transfer of signals between two interconnected layouts.
When choosing an elastomeric connector, you need to consider the following factors:
- The number of conductors required
- The current carrying capacity required
- The environmental conditions the connector will be exposed to
- The cost
- The ease of assembly
Elastomeric connectors can connect RF and high frequencies as well. Whether it is impedance controlled differential pairs or single line coaxial connectors, both can be implemented with elastomeric technology.

The typical resistance of an elastomeric connector is under 0.5Ω. The wider the contact pad the lower is the resistance. For 0.5mm pitch pads typical resistance is ~100mΩ.
It is dependent of the pad’s width. The rule of thumb is 1A per 1mm pad width and up.
Typical temperature range for operation of an elastomeric connector is -50Ëš to 120ËšC (-65Ëš to +250ËšF).
