The **WJPA-2CC-R** is a specific electronic component, typically categorized as a **Waterproof Pressure Sensor** or **Pressure Transmitter**, often used in automotive or industrial fluid management systems. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Overview The WJPA-2CC-R is designed to convert physical pressure into a measurable electrical signal. It is built to withstand harsh environments, particularly those involving moisture or chemical exposure. ### 2. Technical Specifications The following table summarizes the primary electrical and physical attributes: | Feature | Specification | | :--- | :--- | | **Component Type** | Pressure Sensor / Transducer | | **Output Type** | Analog (Typically Voltage or Current Loop) | | **Housing Material** | Corrosion-resistant alloy / Stainless Steel | | **Connection Type** | Circular Connector (Sealed) | | **Protection Rating** | IP67 or IP69K (Waterproof/Dustproof) | | **Operating Temperature** | -40°C to +125°C (Standard Industrial Grade) | ### 3. Electronic Architecture The internal circuitry generally consists of three main stages: 1. **Sensing Element:** A piezo-resistive or capacitive element that changes its electrical properties when physical force is applied. 2. **Signal Conditioning:** An onboard ASIC (Application-Specific Integrated Circuit) that amplifies the micro-signals from the sensor and compensates for temperature fluctuations. 3. **Output Driver:** Standardizes the signal for the ECU (Electronic Control Unit) or PLC, ensuring low noise and signal integrity over long cable runs. ### 4. Typical Pinout Configuration While specific wiring depends on the manufacturer's datasheet, the 2CC series usually follows this standard: * **Pin 1 (VCC):** Power supply input (usually 5V or 12-24V DC). * **Pin 2 (GND):** Common ground. * **Pin 3 (OUT):** Analog signal output (0.5V – 4.5V or 4-20mA). --- ### 5. Common Applications * **Automotive:** Monitoring fuel pressure, oil pressure, or air conditioning coolant levels. * **Industrial:** Hydraulic systems, pneumatic lines, and water treatment plants. * **HVAC:** Refrigerant pressure monitoring in high-efficiency cooling units.
