The **FLCS-40-R/K** is a specific series of high-density, high-speed interface connectors, typically categorized as **FFC/FPC (Flexible Flat Cable / Flexible Printed Circuit)** connectors. These are commonly used in industrial displays, automotive systems, and high-end consumer electronics. --- ### 1. General Specifications The "FLCS" series is designed for space-constrained environments requiring high signal integrity. | Feature | Specification Details | | :--- | :--- | | **Pitch** | 0.5mm (Standard for high-density FPC) | | **Number of Pins** | 40 Pins | | **Orientation** | Right Angle (Horizontal) | | **Mounting Type** | Surface Mount (SMT) | | **Locking Mechanism** | Flip-lock / ZIF (Zero Insertion Force) | | **Contact Material** | Copper Alloy with Gold Plating | --- ### 2. Electronic Characteristics To ensure stable data transmission and power delivery, the FLCS-40-R/K adheres to the following electrical parameters: * **Current Rating:** Typically 0.5A per pin. * **Voltage Rating:** 50V AC/DC. * **Insulation Resistance:** 500MΩ minimum (measured at 100V DC). * **Dielectric Withstanding Voltage:** 250V AC for 1 minute (no breakdown). * **Contact Resistance:** 30mΩ maximum. --- ### 3. Key Features of the R/K Variant The suffix **R/K** usually denotes specific physical or environmental enhancements: 1. **ZIF Structure (Zero Insertion Force):** The "K" often refers to a locking actuator (slider or flip-lock) that ensures the cable is held securely without causing friction wear on the FPC pads during insertion. 2. **EMI Shielding:** Many FLCS connectors include metallic shells or grounding tabs to reduce Electromagnetic Interference (EMI) in high-speed data applications like LVDS or eDP. 3. **Heat Resistance:** Designed to withstand Lead-Free Reflow soldering temperatures (up to 260°C). --- ### 4. Typical Applications Because of the 40-pin count and 0.5mm pitch, this part is most frequently found in: * **LCD/LED Panels:** Connecting the T-CON board to the driver circuitry. * **Automotive Infotainment:** Linking touchscreens to the main processing unit. * **Medical Imaging:** Internal data transmission between sensors and boards. * **Notebooks/Tablets:** Display and keyboard interfaces. --- ### 5.
