The **PS86-204P-H-R2** is a high-precision, pressure-sensitive electronic component, specifically a **pressure transducer/switch** manufactured by Nidec Components (formerly Copal Electronics). It is designed to measure hydraulic or pneumatic pressure in industrial environments. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Feature | Specification | Detail | | :--- | :--- | :--- | | **Pressure Range** | 0 to 2 MPa (approx. 20 bar) | Measures positive gauge pressure. | | **Output Type** | PNP Open Collector | High-side switching for digital logic. | | **Accuracy** | ±3% F.S. (Full Scale) | Includes linearity, hysteresis, and repeatability. | | **Operating Voltage** | 12 to 24 V DC | Standard industrial power rail compatibility. | | **Port Thread** | R2 (PT 1/4) | Tapered pipe thread for mounting. | | **Sensing Element** | Piezoresistive | Uses a silicon-on-thin-film diaphragm. | --- ### 2. Internal Electronic Architecture The device consists of three primary electronic stages: 1. **The Piezoresistive Bridge:** A diaphragm with integrated resistors. When pressure is applied, the resistance changes (piezoresistive effect), creating a small differential voltage. 2. **Signal Conditioning (ASIC):** An internal circuit amplifies the micro-volt signal, compensates for temperature fluctuations, and stabilizes the output. 3. **Output Driver (PNP):** The processed signal triggers a PNP transistor. When the pressure setpoint is reached, the transistor closes the circuit between the V+ supply and the output wire. --- ### 3. Wiring Diagram (Standard Color Codes) Industrial sensors of this type typically follow a standard 3-wire system: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Brown** | Vcc (+) | Connects to 12-24V DC. | | **Blue** | GND (-) | Common ground. | | **Black** | Out (Signal) | The PNP output load connection. | --- ### 4. Typical Applications * **Hydraulic Systems:** Monitoring oil pressure in heavy machinery. * **Pneumatic Control:** Managing air pressure in automated factory lines. * **Water Treatment:** Detecting blockages or pump failures via pressure spikes. ---
