The **1590TRPBYL** is a specific model of an industrial-grade electronics enclosure manufactured by **Hammond Manufacturing**. It is primarily used to house sensitive electronic circuits that require physical protection and environmental shielding. --- ## 1. Technical Specifications The part number follows a specific naming convention used by Hammond to denote size, shape, and finish. | Attribute | Specification | | :--- | :--- | | **Manufacturer** | Hammond Manufacturing | | **Series** | 1590 (Diecast Aluminum Enclosures) | | **Shape** | Trapezoidal | | **Color** | Yellow (BYL - Bright Yellow) | | **Material** | Diecast Aluminum Alloy (ADC12) | | **Wall Thickness** | ~2mm (nominal) | | **IP Rating** | IP54 (Standard) | --- ## 2. Key Physical Features ### Trapezoidal Design Unlike the standard rectangular 1590 series, the **TRP** designation stands for **Trapezoidal**. This unique shape is highly favored in the musical electronics industry (specifically for guitar effects pedals) as it provides a wider base for stability and a distinctive aesthetic. ### Material & Shielding * **EMI/RFI Shielding:** Since the body is made of diecast aluminum, it naturally acts as a Faraday cage. This protects the internal electronic components from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). * **Vibra-finish:** The aluminum is typically smoothed before painting to ensure no sharp edges and a professional finish. ### Finish (Yellow Powder Coat) The **BYL** suffix indicates a **Bright Yellow** polyester powder coat. This provides: * Corrosion resistance. * High visibility. * A durable surface that resists chipping and scratching compared to standard liquid paint. --- ## 3. Common Applications Due to its rugged nature and shielding capabilities, the 1590TRPBYL is commonly found in: 1. **Guitar Effects Pedals:** Used by boutique pedal builders for "boutique" or custom stompboxes. 2. **Industrial Controls:** Housing for small switches or sensors in factory environments. 3. **Test Equipment:** Portable handheld devices that need a sturdy, shielded casing. --- ## 4. Mounting & Assembly The unit consists of two main parts: the **body** and the **lid**. ```markdown * **Fasteners:** Usually includes 4 machine screws (6-32 x 1/2"). * **Holes:** The enclosure is easy to drill or mill for potentiometers, LEDs, and jacks. * **Grounding:** The lid and box are typically joined in a way that maintains electrical continuity for grounding purposes. ``` ---
