The **E200-R22-B1LR** is a specific technical model typically associated with high-precision industrial components, most commonly found in the catalog of **SMC Corporation** (as an electric actuator or pressure switch derivative) or specialized automotive/sensor electronics. Based on industrial standards for this part number, here is an explanation of its electronic and mechanical characteristics. --- ### 1. General Specifications The E200 series usually refers to compact electronic units designed for automation control. | Feature | Description | | :--- | :--- | | **Component Type** | Electronic Pressure Switch / Digital Sensor | | **Circuit Type** | Solid State (NPN or PNP depending on wiring) | | **Connector Type** | M12 or Lead-wire options | | **Display** | LED Digital Display (typically 3.5 digits) | | **Response Time** | $\leq$ 2.5ms (High Speed) | --- ### 2. Breakdown of the Model Code The alphanumeric string "E200-R22-B1LR" defines its specific electronic configuration: * **E200:** The base series designation (Electronic Sensor/Actuator unit). * **R22:** Indicates the **Pressure Range** or **Resistance Value**. In pressure sensors, this often denotes a range of -0.1 to 1.0 MPa. * **B1:** Defines the **Output Specification**. Usually signifies a single switch output (NPN) + Analog output (1-5V). * **L:** Represents the **Lead Wire length** or connection style (e.g., L = 3 meters). * **R:** Signifies a **Right-angle connector** or a specific Mounting Bracket orientation. --- ### 3. Electronic Architecture Inside the unit, several key electronic stages process signals: 1. **Sensing Element:** A piezoresistive silicon chip that converts physical pressure into a millivolt signal. 2. **Signal Conditioning:** An internal Op-Amp circuit that amplifies the low-level signal and filters out electromagnetic interference (EMI). 3. **Microcontroller (MCU):** Converts the analog signal to digital for the display and compares it against the user-defined "Set Points." 4. **Output Stage:** Uses power transistors (MOSFETs) to switch external loads (PLCs, Relays). --- ### 4. Wiring Diagram (Typical) Most units in this class follow a standard industrial 3-wire or 4-wire color code: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Brown** | Vcc (+) | DC 12-24V Power Input | | **Blue** | 0V (-) | Ground/Common | | **Black** | OUT 1 | Digital Switching Output | | **White/Grey** | Analog | 1-5V or 4-20mA Signal | --- ### 5. Application Use-Cases * **Pneumatic Monitoring:** Detecting pressure drops in automated assembly lines. * **Vacuum Verification:** Ensuring a suction cup has successfully grabbed a part. * **Leak Testing:** Monitoring a sealed system for electronic decay in pressure over time. ---
