The **LPCE-514-R/Q** is a high-performance power connector, typically used in server, networking, and industrial power supply applications. It is part of the **PwrBlade+** or similar high-power connector series designed to provide both power and signal transmission in a single compact housing. --- ### 1. Technical Specifications The "R/Q" suffix usually denotes specific mounting styles (Right Angle or Vertical) and plating options. Below are the general electronic and physical characteristics: | Property | Description | | :--- | :--- | | **Current Rating** | Up to 30A per power contact (dependent on PCB layout) | | **Voltage Rating** | 600V AC/DC | | **Contact Resistance** | < 2.0 mΩ (initial) | | **Insulation Resistance** | > 5000 MΩ | | **Operating Temperature** | -40°C to +125°C | | **Pitch** | 2.50mm to 3.00mm (Signal) / 6.00mm+ (Power) | --- ### 2. Key Electronic Components & Features #### A. Power Contacts The core of the LPCE series is its **high-conductivity copper alloy** contacts. These are engineered to handle high current loads with minimal heat dissipation (I²R loss). The contacts are often gold-plated at the mating interface to ensure low resistance and prevent oxidation. #### B. Signal Pins Unlike pure power cables, the LPCE-514 includes dedicated signal pins. These are used for: * **Power Management:** Sensing voltage drops. * **I2C/SMBus Communication:** Reporting PSU (Power Supply Unit) status to the motherboard. * **Presence Detection:** Allowing the system to know when a module is plugged in. #### C. Housing (The Dielectric) The body is made of high-temperature thermoplastic (UL 94 V-0 rated). This material is chosen for: * **High Dielectric Strength:** Preventing arcing between high-voltage power pins. * **Reflow Compatibility:** Ensuring the part can withstand lead-free soldering temperatures during PCB assembly. --- ### 3. Connection Architecture The connector typically follows a **Blind-Mate** or **Hot-Plug** design logic: 1. **Grounding First:** Usually designed so the ground pin connects before the power pin. 2. **Sequential Mating:** Different pin lengths allow the system to establish ground, then power, then signal, protecting sensitive electronics from surges. --- ### 4. Common Applications * **Data Centers:** High-density server blade power distribution. * **Telecom:** Base station power modules. * **Industrial:** High-current motor controllers or modular power supplies.
