The **PCC-SMP-U-50-R** is a specialized electronic component primarily used in temperature measurement and instrumentation. It is a surface-mount connector designed for thermocouples. ### 1. General Specifications This part is a subminiature thermocouple connector designed to be mounted directly onto a Printed Circuit Board (PCB). | Feature | Specification | | :--- | :--- | | **Manufacturer** | Omega Engineering | | **Connector Type** | PCC (PCB Connector) | | **Calibration Type** | Type U (Uncompensated/Copper) | | **Mounting Style** | Surface Mount (SMD/SMT) | | **Orientation** | Right-Angle / Horizontal | | **Package Quantity** | 50 (indicated by the "-50" suffix) | --- ### 2. Key Electronic Features #### A. Calibration Type (Type U) The "U" in the part number stands for **Uncompensated**. - Unlike Type K or Type J connectors which use specific thermocouple alloys, Type U uses **copper pins**. - It is typically used for RTDs (Resistance Temperature Detectors) or for situations where the thermocouple compensation is handled elsewhere on the circuit board. #### B. Mounting Mechanism - **Surface Mount (SMT):** Designed to be soldered onto the surface of a PCB rather than through holes. - **Transistor Retaining Clip:** The "-R" suffix indicates the inclusion of a **retaining clip**. This clip provides mechanical stability, ensuring the connector stays securely attached to the board even when the mating plug is inserted or removed. #### C. Contact Material The pins are usually made of copper with a gold or nickel plating to ensure high conductivity and resistance to oxidation, which is critical for low-voltage signal integrity. --- ### 3. Application and Usage This part is commonly found in industrial and laboratory environments where temperature data needs to be logged or monitored via a compact electronic device. * **Handheld Thermometers:** Internal PCB connection for external probes. * **Data Loggers:** Small-scale devices requiring multiple thermocouple inputs. * **OEM Instrumentation:** Integrated into custom control panels. --- ### 4. Mechanical Dimensions (Typical) While exact dimensions should be verified via the datasheet, the **SMP** (Subminiature) series generally follows these constraints: - **Pin Spacing:** Designed for standard subminiature thermocouple plugs. - **Profile:** Low profile to fit within slim electronic enclosures. ---
