Custom Engineered Connection Solutions

Connectronics Corp. manufactures a broad range of connection products developed for mission-critical use. Our core offerings include high voltage connectors, high current connectors, underwater connectors, and specialized connector systems. Each category is built for exacting performance and is available in standard and custom configurations.

High Voltage Connectors

High Voltage Connectors

High Voltage Connectors

These high voltage connectors are built to handle voltages ranging from 5 kV to 60 kV. They are often used in aerospace power distribution, military radar systems, and medical diagnostic equipment. We engineer these products to function in environments with extreme temperatures, pressure changes, and electromagnetic interference.

Each product line—such as our CMC-715, MIDGI, SCID, and HVL series—offers unique performance features. They support both cable-to-panel and cable-to-cable connections, and include internal shielding, arc suppression, and sealing features to resist moisture, chemicals, and mechanical vibration. Corona resistance and high dielectric strength are key benefits in these designs.

High Current Connectors

Our high current connectors support efficient and secure transmission of electrical current in the 200 to 1000 amp range. Applications include laser systems, battery packs, pulse power systems, and motor control. These connectors are engineered with copper alloys, advanced insulation materials, and locking mechanisms to support repeated use under load.

One popular option is the Safety Lock series, which features a contact-first, break-last configuration to prevent arcing. These connectors can be configured for single or multiphase applications and are commonly used in ground equipment and mobile power distribution.

Underwater Connectors

Underwater Cables & Connectors Product

Underwater Connectors

Built to operate in harsh marine or subsea environments, our underwater connectors are manufactured with stainless hardware, elastomeric sealing, and thermoplastic overmolds. These assemblies are pressure tested and rated to perform in depths ranging from shallow dive equipment to deep-sea monitoring platforms.

Cable assemblies include molded strain reliefs and integrated sealing boots to prevent moisture ingress and corrosion. Applications include sonar systems, unmanned underwater vehicles (UUVs), offshore oil and gas equipment, and defense platforms.

Specialized Connectors & Cable Assemblies

We also manufacture specialized connectors designed for specific technical and environmental requirements. These may include high-temperature performance, radiation resistance, vacuum compatibility, or tight mechanical envelopes.

Applications often come from the medical, aerospace, or nuclear sectors. We support everything from MRI and X-ray systems to spacecraft avionics. Our wire and cable assemblies use silicone-coated insulation, etched FEP and PFA, and low outgassing materials. High-voltage wires are available from 1 kV to 30 kV and are built to maintain dielectric integrity under stress.

Whether the challenge involves temperature, vibration, or electromagnetic interference, we provide solutions that meet exact application demands.
