The **FCR-B6-R/Q** refers to a high-speed, high-density rectangular connector series, typically manufactured by companies like **Hirose (HRS)**. These are widely used in industrial automation, medical equipment, and high-end telecommunications. --- ### 1. Technical Specifications The "R/Q" designation often refers to the specific housing or contact style (Receptacle/Quick-locking). Below is a breakdown of the typical electrical and physical parameters: | Feature | Specification | | :--- | :--- | | **Connector Type** | High-density Rectangular | | **Number of Pins** | 6 Pins | | **Current Rating** | 2A to 3A (depending on wire gauge) | | **Voltage Rating** | AC 300V / DC 400V | | **Contact Resistance** | 30 mΩ Max | | **Insulation Resistance** | 1000 MΩ Min at 500V DC | | **Operating Temp** | -25°C to +85°C | --- ### 2. Key Electronic Components & Materials The performance of the FCR-B6-R/Q is defined by its material composition: * **Contacts (Pins/Sockets):** Usually made of **Phosphor Bronze** or Copper Alloy with **Gold plating** over Nickel. Gold is used to prevent oxidation and ensure low contact resistance over thousands of mating cycles. * **Insulator (Body):** Made of high-grade synthetic resin (like PBT or PPS). These materials are chosen for their high dielectric strength and resistance to heat during soldering. * **Shielding:** Many "R/Q" variants include a metal shell (Zinc alloy or Stainless steel) for **EMI (Electromagnetic Interference)** protection, which is critical for high-speed signal integrity. --- ### 3. Connection & Wiring Styles The electronic integration of this part usually follows one of three methods: 1. **Crimp Termination:** Individual wires are crimped into metal terminals and inserted into the B6 housing. 2. **Solder Cup:** Wires are soldered directly into the back of the connector pins. 3. **PCB Mount:** (If the "R" stands for a right-angle receptacle) The pins are soldered directly into a Printed Circuit Board. --- ### 4. Application Logic The FCR-B6 series is favored in "Blind-mating" scenarios where the user cannot see the connection point. The **"Q" (Quick-lock)** mechanism provides tactile feedback (a click) to ensure the electronic circuit is fully closed, preventing partial contact which could lead to arcing or data loss.
