The MX150 Sealed Plug Connector, part number 33482-3604 with Key D, is a robust and reliable electrical interconnect solution designed for demanding environments where moisture, dust, and other contaminants pose a risk to connection integrity. This connector belongs to a high-performance sealed connector series, engineered to meet stringent industry standards for durability and environmental resistance. Design and Construction The MX150 Sealed Plug Connector features a rugged thermoplastic housing that provides excellent resistance to impact, vibration, and harsh conditions. The sealing mechanism includes integrated gaskets and O-rings, ensuring an IP67 or higher ingress protection rating. This makes it suitable for applications exposed to water, dirt, and extreme temperatures. The connector utilizes a Key D polarization system, which ensures proper mating alignment and prevents incorrect insertion with incompatible receptacles. This keying feature enhances safety and reliability in complex wiring systems. The housing is designed with a secure locking mechanism, typically a push-pull or screw-lock system, to maintain a stable connection even under mechanical stress. Electrical and Performance Specifications This plug connector supports multiple contact configurations, accommodating a range of wire gauges depending on the specific variant. The contacts are precision-engineered from high-conductivity materials, such as brass or phosphor bronze, with gold or tin plating to ensure low resistance and corrosion resistance. Rated for voltages up to 250V and currents up to 13A per contact, the MX150 Sealed Plug Connector is suitable for automotive, industrial machinery, marine, and outdoor equipment applications. Its insulation resistance and dielectric strength comply with international safety standards, ensuring reliable performance in high-voltage environments. Applications Common uses include: - Automotive systems (sensors, lighting, control modules) - Industrial automation (motor connections, control panels) - Outdoor electronics (LED lighting, agricultural equipment) - Marine and off-road vehicles (exposed electrical connections) Installation and Maintenance The connector is designed for easy assembly, with crimp or solder contact termination options. Strain relief features prevent wire pull-out, while color-coded housings simplify identification during installation. Maintenance is minimal due to its sealed design, though periodic inspection for seal integrity is recommended in extreme conditions. In summary, the MX150 Sealed Plug Connector (Key D, 33482-3604) is a durable, high-performance interconnect solution ideal for harsh environments. Its combination of sealing technology, secure locking, and electrical reliability makes it a preferred choice for engineers requiring long-term connectivity solutions.
