The **SVB-15E-R** is a specific model of a **Vacuum Solenoid Valve**, typically manufactured by companies like **Koganei** or similar industrial automation providers. These parts are critical in pneumatic systems where precision control of vacuum flow is required. --- ### ## Technical Specifications Overview Below is a breakdown of the typical electronic and mechanical characteristics of the SVB series: | Feature | Specification | | :--- | :--- | | **Valve Type** | Solenoid-controlled Vacuum Valve | | **Action Type** | Normally Closed (NC) or Normally Open (NO) | | **Operating Voltage** | Typically 24V DC (Standard for PLCs) | | **Power Consumption** | Low wattage (approx. 0.5W to 1.5W) | | **Response Time** | High-speed switching (often <15ms) | | **Connection Port** | Sub-base or Manifold mounting | | **Indicator** | LED status light (Standard on "R" suffix models) | --- ### ### Key Electronic Components & Features #### 1. Solenoid Coil The "heart" of the device. When an electrical current (24V DC) passes through the copper windings, it creates an electromagnetic field. This field pulls a plunger or armature to open or close the vacuum path. #### 2. Surge Suppressor (The "R" Suffix) The **"R"** in the part number usually indicates the presence of a **Surge Suppressor** (often a Diode or MOV) and an **LED Indicator**. * **Protection:** It prevents "Back-EMF" (voltage spikes) from traveling back to the PLC or controller when the coil is de-energized. * **Visual Feedback:** The LED provides an immediate visual cue for troubleshooting, showing if the valve is receiving power. #### 3. Lead Wire or Plug-in Connector These units typically come with either: * **L-Plug:** A vertical plug-in connector. * **M-Plug:** A horizontal plug-in connector. * **Grommet:** Integrated wires extending directly from the coil. --- ### ### Function in a System The SVB-15E-R acts as the interface between the **Electronic Control Layer** (PLC/PC) and the **Physical Vacuum Layer**. 1. **Input:** The PLC sends a 24V DC signal. 2. **Activation:** The internal solenoid coil energizes. 3. **Mechanical Action:** The valve shifts, allowing a vacuum pump to draw air from a suction cup. 4. **Result:** A component is picked up by the vacuum. ---
