### Overview of JAPD2-5N-R The **JAPD2-5N-R** is a specialized electronic component, typically categorized as a **Pressure Sensor** or **Pressure Switch**, often utilized in industrial automation and fluid power systems (Pneumatics/Hydraulics). Below is a breakdown of its technical specifications and electronic characteristics. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Digital Pressure Switch / Sensor | | **Pressure Range** | Generally -0.1 to 1.0 MPa (Standard for 5N series) | | **Output Type** | NPN Open Collector | | **Power Supply** | 12 to 24 VDC | | **Port Size** | M5 × 0.8 or R1/8 (depending on specific sub-fitting) | | **Response Time** | ≤ 2.5ms | --- ### Key Electronic Components & Functions 1. **Sensing Element (Piezo-resistive):** * The core is a silicon-based micro-machined pressure sensor. It converts mechanical pressure into a small electrical voltage change via the piezo-resistive effect. 2. **Signal Conditioning Circuit:** * Uses an internal operational amplifier (Op-Amp) to amplify the millivolt signal from the sensor to a level that can be processed by the internal MCU. 3. **Microcontroller (MCU):** * Handles the digital logic, allowing the user to set "Switch Points" (thresholds). It monitors the pressure and determines when to trigger the output. 4. **NPN Output Stage:** * The "5N" designation usually indicates an **NPN** transistor output. When the set pressure is reached, the transistor closes the circuit to the negative rail (GND), acting as a switch for a PLC input or a relay. 5. **Digital Display (LED/LCD):** * Provides real-time visual feedback of the current pressure reading and helps in programming setpoints. --- ### Wiring Diagram (Typical) Most units in this series follow a standard 3-wire color code: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Brown** | V+ | Positive Power Supply (12-24V) | | **Blue** | 0V / GND | Negative Power Supply / Common | | **Black** | OUT | NPN Switch Output (Connect to Load) | --- ### Application Usage * **Leak Detection:** Monitoring pressure drops in sealed systems. * **Pick-and-Place:** Confirming vacuum or pressure levels before moving a component. * **Process Control:** Ensuring pneumatic actuators have sufficient line pressure to operate safely.
