The **RHP-10B-R02FYR** is a specific model within the RHP series of industrial sensors, typically manufactured by companies like **KOGANEI**. This device is a compact, high-precision electronic pressure sensor designed for pneumatic systems. --- ### 1. Key Technical Specifications The following table outlines the core electronic and physical characteristics of this part: | Feature | Specification | | :--- | :--- | | **Component Type** | Digital Pressure Sensor / Switch | | **Pressure Range** | Generally 0 to 1.0 MPa (Positive Pressure) | | **Output Type** | 2 NPN Open Collector Outputs + Analog Output (1-5V) | | **Power Supply** | 12 to 24V DC (±10%) | | **Display** | 3½ Digit, 2-color LCD (Red/Green) | | **Connection Type** | M8 4-pin Connector or Lead Wire (model dependent) | | **Port Size** | R1/8 or M5 (Universal Thread) | --- ### 2. Internal Electronic Components To achieve high precision and reliability, the RHP-10B-R02FYR incorporates several internal electronic subsystems: * **Piezoresistive Transducer:** The "heart" of the sensor. It converts mechanical pressure into a small electrical voltage change. * **Signal Conditioning ASIC:** An Application-Specific Integrated Circuit that amplifies the raw signal, compensates for temperature fluctuations, and converts it into a digital value. * **Microcontroller (MCU):** Manages the logic for the dual outputs, processes the user-defined setpoints (Hysteresis/Window modes), and drives the LCD display. * **Output Transistors:** NPN switches that allow the sensor to trigger external PLC inputs or relays when pressure thresholds are met. --- ### 3. Functional Wiring Logic The electronic interface usually follows a standard 4-wire color code: ```yaml Brown: DC (+) 12-24V Blue: DC (-) 0V / GND Black: Output 1 (Digital NPN) White: Output 2 (Digital NPN) or Analog (1-5V) ``` --- ### 4. Typical Applications * **Suction Verification:** Confirming a vacuum part is held securely in robotic pick-and-place. * **Leak Testing:** Monitoring pressure drops in sealed systems. * **Supply Monitoring:** Ensuring pneumatic lines maintain the minimum required pressure for tool operation.
