Circular Connectors Trim-Trio

Trim-Trio circular connector features a wide variety of insert arrangements for plastic, metal, and bi-metal connectors. They are fitted with gauge contacts for signal, coaxial, and fiber-optic power Connections. For many industrial markets a cost-effectibe solution.

The design of the Trim-Trio connectors is based on a simple concept: enable manufacturers to use a single
type of contact for different types of connector in order to simplify the management of their shell and contact
inventories and tailor their connectors to specific applications. For example, a plastic, metal, or bi-metal connector may be used in different environments, but the form-factor of the insert arrangement is the same and the connectors are both interchangeable and intermateable.
