Designed by Woodhead, a trusted name in industrial connectivity, this connector combines robust construction with field-proven performance to meet the rigorous demands of automation, control systems, and power distribution applications. Its patented Quad-Beam™ contact design ensures low electrical resistance and exceptional reliability, even under vibration, thermal cycling, or harsh operating conditions. This 4-pole connector supports secure connections for applications requiring up to 600V AC/DC, making it ideal for use in industrial automation, machine control, sensor networks, and equipment wiring where consistent performance is critical. Engineered for field attachability, the CA4000-39 eliminates the need for pre-molded connectors, enabling on-site assembly and quick repairs. This reduces installation time, minimizes downtime, and lowers total cost of ownership by allowing technicians to attach or replace connectors directly in the field without specialized tooling. The connector accommodates wire sizes from 15 to 24 AWG and cable diameters between 5.08 and 11.43mm, providing flexibility across a wide range of cable types and gauges commonly used in industrial settings. Constructed with a durable nylon body and polyurethane connector face, the CA4000-39 delivers superior mechanical strength and environmental resistance. The brass contacts are gold-over-nickel plated for enhanced corrosion resistance and long-term conductivity, while the nickel-plated brass coupling nut ensures secure mating and easy handling in tight spaces. With an operating temperature range of -20°C to +80°C and IP67-rated protection against dust and water ingress, this connector is built to perform reliably in outdoor enclosures, factory floors, and mobile equipment exposed to moisture, dirt, and temperature extremes. The Quick-Change® series from Woodhead is widely recognized in the industrial sector for its ease of use, durability, and compatibility with existing systems. Professionals in automation, electrical contracting, and OEM equipment manufacturing rely on these connectors for their consistent performance and long service life. Whether used in panel wiring, cable assemblies, or field service repairs, the CA4000-39 provides a dependable, high-integrity connection that meets UL safety standards (UL File No. E258922) and supports mission-critical operations. Trusted by engineers and technicians worldwide, Woodhead connectors are a preferred choice for applications where reliability, safety, and ease of maintenance are non-negotiable.
