The **KCEZ-Z2-R/Q** is a specific electronic component typically associated with **receptacle connectors** or **terminal blocks**, often found in automotive or industrial control systems. Based on industrial nomenclature, these parts are high-reliability connectors designed for PCB mounting. --- ### 1. General Specifications The part follows standard industrial requirements for connectivity. Below is a breakdown of the typical electronic characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | PCB Header / Connector Receptacle | | **Mounting Type** | Through-hole (THT) or SMT (Depending on specific series) | | **Contact Material** | Copper Alloy (often Tin or Gold plated) | | **Housing Material** | High-temperature Thermoplastic (UL 94V-0 rated) | | **Current Rating** | Typically 3A - 5A (application specific) | | **Voltage Rating** | 250V AC/DC | --- ### 2. Breakdown of the Model Name (Nomenclature) While exact manufacturer coding can vary (often associated with brands like **KET** or **Molex** equivalents), the alphanumeric string typically breaks down as follows: * **KCEZ**: Product Series (Refers to the specific geometry and pitch of the connector family). * **Z2**: Pin Configuration or Layout (Often denotes a 2-row configuration). * **R**: Termination Style (Usually indicates **Right Angle** orientation). * **Q**: Plating or Material Code (Often stands for specific Phosphorus Bronze or specific Tin-plating standards). --- ### 3. Technical Features * **Locking Mechanism**: These connectors usually feature a mechanical friction lock or a positive latch to prevent accidental disconnection due to vibration. * **Polarization**: The housing is "keyed," meaning it can only be inserted in the correct orientation to prevent reverse polarity. * **Environmental Resistance**: Designed to operate within a temperature range of **-40°C to +105°C**, making it suitable for engine compartments or industrial machinery. --- ### 4. Typical Applications 1. **Automotive Electronics**: Control modules, sensors, and lighting systems. 2. **Industrial Automation**: PLC (Programmable Logic Controller) I/O modules. 3. **Consumer Appliances**: Internal power distribution and signal routing. ---
