The **1590WPFBK** is a specific model of electronic enclosure manufactured by **Hammond Manufacturing**. It is designed to house electronic components, PCBs (Printed Circuit Boards), and various instrumentation in rugged environments. --- ### 1. Key Technical Specifications The model number provides specific information about its design and features: | Feature | Specification | |:---|:---| | **Manufacturer** | Hammond Manufacturing | | **Material** | Die-cast Aluminum Alloy (Tough yet easy to machine) | | **Finish** | Black Polyester Powder Paint | | **Waterproofing** | IP65 Rated (Watertight) | | **Wall Type** | Flanged Lid (for easy wall or surface mounting) | | **Outer Dimensions** | Approximately 112 x 60 x 31 mm | --- ### 2. Physical Components & Parts The assembly of the 1590WPFBK typically consists of the following internal and external parts: #### A. The Body (Chassis) * **Lap Joint Construction:** The edges of the body are designed to interlock with the lid to provide protection against dust and splashing water. * **Vibra-finish:** Before painting, the aluminum is tumbled to ensure a smooth surface with no sharp burrs. #### B. The Lid (Flanged) * The "PF" in the part number denotes a **Flanged Lid**. This means the lid extends beyond the body of the box with pre-drilled holes, allowing you to screw the entire unit onto a wall, vehicle, or machinery without opening the box. #### C. Sealing Gasket * **Material:** Silicone Rubber. * **Function:** This gasket sits in the lap joint. When the lid is screwed down, it creates a watertight seal (IP65 rating), protecting internal electronics from moisture and rain. #### D. Hardware * **Screws:** Usually comes with 6-32 x 1/2" stainless steel machine screws. * **Factory Holes:** The body has factory-tapped holes, so the screws secure metal-to-metal, which is more durable than self-tapping screws into plastic. --- ### 3. Electronic Applications Because it is made of aluminum, this enclosure offers specific electrical advantages: 1. **EMI/RFI Shielding:** The metal construction naturally acts as a Faraday cage, protecting sensitive internal circuits from electromagnetic interference. 2. **Grounding:** The enclosure can be used as a common ground for a circuit. 3. **Heat Dissipation:** Aluminum acts as a giant heat sink, helping to pull heat away from internal power components (like voltage regulators or transistors). --- ### 4. Common Modifications Engineers often modify this enclosure by adding: * **Cable Glands:** To maintain the IP65 rating while running wires into the box. * **Standoffs:** To mount PCBs securely inside. * **LED Indicators:** Drilled through the face with waterproof bezels.
