The **FCRS-55-R** typically refers to a high-precision, flexible circuit or specialized sensor connector assembly often used in industrial automation, robotics, or high-density electronics. Below is a breakdown of the electronic and mechanical characteristics associated with this part. --- ### 1. General Specifications The FCRS series is known for its **Flexible Circuit (FPC) compatibility** and robust signal integrity. | Feature | Specification | | :--- | :--- | | **Type** | Flexible Printed Circuit (FPC) Connector / Ribbon Assembly | | **Pitch** | Typically 0.5mm to 1.0mm (depending on specific revision) | | **Orientation** | Right-Angle (indicated by the "-R" suffix) | | **Contact Material** | Phosphor Bronze or Gold-plated Copper Alloy | | **Current Rating** | 0.5A to 1.0A per contact | | **Voltage Rating** | 50V - 125V AC/DC | --- ### 2. Key Electronic Components & Materials To understand the "electronic parts" of the FCRS-55-R, we must look at the assembly stack: #### A. Conductive Traces * **Material:** High-purity Rolled Annealed (RA) Copper. * **Function:** Provides the electrical path for data and power. In the FCRS-55-R, these are etched to precise widths to maintain impedance control. #### B. The Housing (Insulator) * **Material:** LCP (Liquid Crystal Polymer) or PPS (Polyphenylene Sulfide). * **Function:** These high-temperature thermoplastics are used because they remain stable during reflow soldering and provide excellent electrical insulation between pins. #### C. Locking Mechanism (Actuator) * **Design:** Usually a Flip-lock or ZIF (Zero Insertion Force) mechanism. * **Electronic Role:** Ensures a constant "Normal Force" on the FPC cable, preventing intermittent signals or "contact bounce" in high-vibration environments. --- ### 3. Applications Due to its design, the FCRS-55-R is commonly found in: 1. **Industrial Robotics:** Connecting sensors in articulated arms where flexibility is required. 2. **Display Panels:** Interfacing LCD/OLED drivers to main logic boards. 3. **Medical Devices:** Compact, high-reliability signal routing in diagnostic tools. --- ### 4. Technical Advantages * **Space Efficiency:** The right-angle ("-R") design allows for a low-profile footprint on the PCB. * **Durability:** Gold plating on the contacts prevents oxidation, which is critical for low-voltage signal transmission. * **EMI Shielding:** Some variants include a ground plane to reduce electromagnetic interference.
