1. Core Model List (With Product Descriptions)

2. Quick Interpretation of Model Naming Rules

Mastering the naming logic can help you quickly identify the core parameters and applicable scenarios of the product:

1. Series Prefix
   • WMTB: Standard connection component series, focusing on general and high-frequency industrial circuit connection scenarios.
   • WMT: Micro-spec connection component series, dedicated to ultra-small size and micro-current circuit transmission.
   • WML: Multi-spec connection component series, covering low-spec to high-load scenarios with diversified size options.
2. Function & Spec Mark
   • HF: High-frequency signal adaptation function, suitable for high-frequency circuit transmission scenarios.
   • HP: High-performance enhancement, improving the component’s stability in high-demand scenarios.
   • Digital spec (e.g., 8.4, 7.5, 46): Core electrical specification of the component, determining the current-carrying capacity and signal adaptation range.
3. Size & Structure Parameter
   • (XXxXX): Installation dimension of the component in millimeters, determining the compatibility with the equipment’s installation space.
   • R: Basic structure type, stable and reliable, suitable for most general industrial connection scenarios.
   • A4: Special customized specification, tailored for non-standard equipment connection needs.
4. Color Identifier
   • YE: Yellow appearance, with high visibility, facilitating quick circuit identification and maintenance in complex wiring environments.

3. Core Advantages of the Three Series Components

1. Diversified Size & Spec CoverageCovers ultra-micro size (15×4mm) to large size (38×19mm), and micro-spec (2.4) to high-load spec (46), meeting the connection needs of micro-equipment, precision instruments and heavy-duty industrial systems.
2. Multi-scenario Function AdaptationProvides HF high-frequency and HP high-performance function options, adapting to high-frequency signal transmission scenarios such as communication and sensor systems.
3. Clear Visual Identification DesignYellow (YE) color models facilitate quick circuit distinction in complex wiring environments, reducing maintenance time and error rates.
4. Strong Compatibility & Easy InstallationAdopts standard R-type basic structure, compatible with Phoenix’s mounting rails and terminal blocks, realizing quick plug-in and replacement, suitable for dense wiring in control cabinets.
5. Industrial-grade Stable PerformancePasses strict high-temperature, high-humidity and vibration resistance tests, with stable operation in harsh industrial environments, ensuring long-term reliable circuit connection.

4. Product Selection Suggestions

1. Series Selection Based on Scenario Requirements
   • For high-frequency signal transmission: Select WMTB or WML series models with HF suffix.
   • For micro-equipment internal wiring: Choose WMT series ultra-micro spec models (2.4–8.4).
   • For heavy-load industrial circuit connection: Adopt WML series high-spec models (22–46).
   • For general industrial connection: Select WMTB series standard models.
2. Size Matching According to Installation SpaceMeasure the equipment’s installation space dimensions, and select the component model with matching (XXxXX) size; for compact installation environments, prioritize WMT series ultra-small size models.
3. Function & Specification Selection
   • For high-demand scenarios: Choose models with HP high-performance suffix.
   • For customized equipment connection: Select WML series models with A4 special specification.
   • For complex wiring identification: Adopt models with YE yellow appearance.
4. Cost Optimization SuggestionFor non-critical general circuits, select basic R-type structure models without additional function suffixes to reduce procurement costs; for key circuits, prioritize models with HF/HP functions to ensure stable performance.
