Multi contact industrial connector Amphenol CBD3W3F00000 with precision machined copper alloy contacts
Product Overview
Positronic's Combo-D series connectors offer a versatile solution for applications requiring mixed contact configurations of power, shielded, air, high voltage, and signal contacts within a single connector body. Available in twenty-two variants across six standard shell sizes, these connectors are designed for professional, industrial, and military quality applications, providing three performance levels for optimal cost-performance ratio. They are suitable for sheltered, non-corrosive indoor and outdoor environments with normal ventilation. The series features precision-machined contacts, including open-entry or PosiBand closed-entry signal contacts, and removable power, shielded, and high voltage contacts with various termination options. Accessories such as mounting hardware, cable support hoods, and locking systems are available.
