The part number **50737** most commonly refers to a specific series of **Wire-to-Board Terminals** or **Housing Connectors** manufactured by companies like **Molex** (though it can also refer to certain hardware components in automotive or industrial catalogs). Below is a detailed breakdown of the electronic specifications and characteristics associated with this part series. --- ## 1. Component Overview: Molex 50737 Series In the electronics industry, the 50737 series typically represents **Crimp Terminals** used within the **Panelmate™** or similar wire-to-board connector systems. These are designed for high-density applications where space is limited. ### Key Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Crimp Terminal (Female/Socket) | | **Pitch (Spacing)** | 1.25mm (Typical for Panelmate) | | **Wire Gauge (AWG)** | 28 AWG to 32 AWG | | **Material** | Phosphor Bronze | | **Plating** | Gold (Au) or Tin (Sn) | | **Current Rating** | ~1.0A per contact (depending on wire) | | **Voltage Rating** | 125V AC/DC | --- ## 2. Technical Characteristics ### Physical Design * **Low Profile:** The 50737 terminals are engineered for ultra-thin electronics like laptops, tablets, and medical monitors. * **Locking Mechanism:** These terminals usually feature a small locking tang that clicks into a plastic housing to ensure they stay seated during vibration. ### Electrical Performance * **Contact Resistance:** Generally below 20mΩ to ensure minimal power loss. * **Durability:** Gold-plated versions are rated for higher mating cycles (up to 30-50 cycles) compared to tin-plated versions. --- ## 3. Common Applications Due to their small footprint, 50737-series connectors are found in: 1. **Consumer Electronics:** Internal wiring for LCD panels and battery connections. 2. **Medical Devices:** Handheld diagnostic tools. 3. **Industrial:** Small-scale sensor interfaces and compact PCB assemblies. --- ## 4. Assembly Requirements To utilize the 50737 series, specific tooling is required to ensure a reliable electrical connection: * **Crimp Tool:** A precision hand crimper or an automated applicator (for mass production). * **Housing:** These terminals must be inserted into a matching plastic shell (e.g., Molex 51146 series) before being plugged into a PCB header. ---
