Koehlke circular connector products are versatile, like your project requirements. All Koehlke circular connectors are modular, small-to-midsize, push-pull latching, cable and PCB mounted, cylindrical interconnects.

Within the Koehlke circular connector family are 7 product series, each with specific mating and environmental attributes. Three are heavy-duty, metal-shell connectors differentiated by how they lock, how they are indexed and their environmental sealing capacity. A fourth group of plastic-bodied connectors are for your lighter-duty, cost-sensitive and/or disposable applications. Watertight and vacuum-tight connectors are available in the product family. Koehlke circular connectors are used in applications where electromagnetic compatibility (EMC) is key, and are designed to carry very low resistance.
