The **PCC-SMP-J-5-R** is a high-performance, sub-miniature connector primarily used in thermocouple and temperature sensing applications. It is designed for mounting directly onto Printed Circuit Boards (PCBs). Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications | Feature | Details | | :--- | :--- | | **Part Number** | PCC-SMP-J-5-R | | **Connector Type** | Miniature PCB Mount Connector | | **Calibration Type** | Type J (Iron / Constantan) | | **Gender** | Female (Jack) | | **Mounting Style** | Right-Angle Solder Mount | | **Packaging** | Reel (Indicated by the "-R" suffix) | --- ### 2. Key Electronic Components & Materials To maintain accuracy in temperature measurement, the materials used in the pins must match the thermocouple calibration standards. * **Positive Terminal (+):** Made of **Iron (Fe)**. * **Negative Terminal (-):** Made of **Constantan (Cu-Ni)**. * **Insulation:** High-quality glass-filled nylon or liquid crystal polymer (LCP), capable of withstanding high-temperature lead-free soldering processes. * **Contact Resistance:** Engineered to be minimal to prevent voltage drops that would lead to inaccurate temperature readings. --- ### 3. Physical & Mechanical Features * **Sub-miniature Design:** Designed for compact electronics where space is at a premium. * **Transistor Retainer Clip:** Often features a small metal clip to secure the connection against vibration. * **Right-Angle Orientation:** The "J-5" configuration typically refers to the 90-degree pin orientation, allowing for horizontal insertion of thermocouple probes onto a vertical or horizontal PCB. * **Polarization:** The sockets are sized differently (Wide/Narrow) to prevent reverse-polarity connection, which would cause inverse temperature readings. --- ### 4. Typical Applications 1. **Handheld Thermometers:** Internal connection point for the probe. 2. **Data Loggers:** Multi-channel temperature recording devices. 3. **Industrial Controllers:** Interfacing thermocouples with PID controllers. 4. **OEM Equipment:** Integration into medical or laboratory thermal analysis tools. ---
