The **PCC-SMP-T-5-R** is a specific type of connector manufactured by **Omega Engineering**. It is designed for use in temperature measurement circuits, specifically for connecting thermocouples to printed circuit boards (PCBs). --- ### 1. Technical Specifications | Parameter | Details | | :--- | :--- | | **Part Number** | PCC-SMP-T-5-R | | **Thermocouple Type** | **Type T** (Copper/Constantan) | | **Connector Type** | Miniature Connector (Male/Plug) | | **Mounting Style** | PCB Mount (Horizontal/Surface) | | **Pin Configuration** | 2-Pin (Polarized) | | **Material** | Liquid Crystal Polymer (LCP) | | **Temperature Rating** | Up to 260°C (500°F) | --- ### 2. Key Component Features #### A. Thermocouple Type (Type T) The "T" in the part number indicates it is calibrated for **Type T thermocouples**. These are made of copper and constantan and are highly stable, often used in cryogenic and low-temperature applications (-200°C to 350°C). The connector body is color-coded **Blue** to match international Type T standards. #### B. Mounting and Connectivity * **PCB Pins:** The connector features small metal pins designed to be soldered directly into a circuit board. * **Retaining Clip:** The "-R" suffix indicates a **Retaining Clip** feature. This is a metal clip that holds the connector securely to the PCB, providing mechanical strain relief so the solder joints don't break when plugging or unplugging sensors. #### C. Material Properties The housing is typically made from high-performance engineered plastics like LCP. This allows the part to withstand high-temperature soldering processes (like reflow soldering) without melting or warping. --- ### 3. Electronic Integration When integrating this part into a circuit, the following electrical considerations apply: * **Cold Junction Compensation (CJC):** Since this connector bridges the thermocouple wire to the PCB traces, it creates a "junction." For accurate readings, a temperature sensor (like a thermistor or IC) should be placed near this connector on the PCB to perform CJC. * **Polarity:** The pins are different sizes (polarized) to ensure the thermocouple is never plugged in backward, which would cause inverse temperature readings. ---
