Miniature connectors

Miniature Connectors

Miniature connectors are used in many applications where SWaP (size, weight, and power) is a critical requirement of a solution’s design.

There is not a single industry out there today that isn’t demanding that equipment gets smaller, lighter, and more functional at the same time.

Following Moore’s law, the miniaturization of electronics has meant moving away from bulky devices to fully mobile versions, including body-worn electronics.

Our miniature connector solutions

Our miniature connectors allow you to move power and/or data (or only power) in ever-smaller devices with lighter, more capable, ultra-miniature solutions – while maximizing ergonomics and robustness.

They increase the performance of your miniature rugged devices, handling mixed signal and power connections in a smaller footprint.
