The **SES-2C4W-R** is a specific model of an **Electronic Sensor Switch**, typically used for cabinet lighting, furniture integration, or proximity-based power control. It operates as a non-contact infrared (IR) switch. --- ### Technical Specifications Below are the primary electronic characteristics and physical parameters for this component: | Feature | Specification | | :--- | :--- | | **Type** | IR Sensor Switch (Door Trigger / Hand Wave) | | **Input Voltage** | 12V - 24V DC | | **Max Load** | 4A (approx. 48W at 12V / 96W at 24V) | | **Sensor Range** | 1cm - 10cm (typically) | | **Output Type** | Constant Voltage | | **Connector Type** | Usually 4-pin or specific mini-connectors | --- ### Core Electronic Components The internal circuitry of the SES-2C4W-R consists of four main functional sections: #### 1. Infrared Transceiver (The Eye) * **IR Emitter:** An LED that constantly pulses infrared light. * **IR Receiver (Photodiode):** Detects the reflection of the IR light. When an object (like a door or hand) comes within range, the light bounces back to this diode. #### 2. Control IC (The Brain) * An integrated circuit (ASIC or Microcontroller) processes the signal from the IR receiver. * It filters out ambient light noise to prevent accidental triggering. * It determines the "Logic Mode" (e.g., Door Mode: Light ON when door is open; Hand Wave Mode: Toggle ON/OFF). #### 3. Power MOSFET (The Switch) * Unlike mechanical switches, this uses a **MOSFET** (Metal-Oxide-Semiconductor Field-Effect Transistor) to handle the electrical load. * This allows for silent switching and high durability since there are no moving parts to wear out. #### 4. Protection Circuitry * Includes **resistors** and **capacitors** for voltage stabilization. * Often includes **Reverse Polarity Protection** to prevent the device from burning out if the +/- wires are connected incorrectly. --- ### Wiring & Logic Configuration The "2C" in the model name often refers to its dual-channel or dual-control capability, while "4W" typically denotes a 4-wire configuration (V+, V-, LED+, LED-). * **Door Mode (Default):** When the sensor is blocked (door closed), the circuit is OPEN (Light OFF). When the blockage is removed (door open), the circuit CLOSES (Light ON). * **Wave Mode:** Passing a hand over the sensor toggles the state from ON to OFF or vice versa.
