The **EE-SX913P-R** is a high-performance, photo-microsensor (u-shaped slot sensor) manufactured by **Omron**. It is specifically designed for industrial automation where space is limited and high reliability is required. --- ### 1. Technical Specifications Below are the primary electronic and physical specifications for the device: | Feature | Specification | | :--- | :--- | | **Sensing Method** | Transmissive (Slot-type) | | **Slot Width** | 5 mm | | **Output Type** | PNP Open Collector | | **Operation Mode** | Light-ON / Dark-ON (Selectable via wiring) | | **Supply Voltage** | 5 to 24 VDC ±10% | | **Current Consumption** | Max. 15 mA | | **Response Frequency** | 3 kHz (High speed) | | **Indicator** | Red LED (Incident light indicator) | | **Cable Type** | Robot Cable (High-flexibility) | --- ### 2. Key Electronic Components & Wiring The device operates using an infrared LED emitter and a phototransistor receiver facing each other across a 5mm gap. #### Output Configuration (PNP) Since this is the **"P"** version, it features a **PNP Open Collector** output. - When the sensor is triggered, the output pin connects to the **Positive (Vcc)** rail. - This is commonly used in European industrial standards and with PLC inputs that are "Sinking." #### Wiring Diagram Logic The sensor usually features four wires or pins: 1. **Brown:** Plus (+V) - 5 to 24 VDC. 2. **Blue:** Minus (0V) - Common. 3. **Black:** Output - Connects to the load/PLC. 4. **Pink:** Mode Selection - Connect to +V for L-ON or 0V/Open for D-ON. --- ### 3. Distinctive Features * **Robot Cable (-R):** The "-R" suffix indicates that the sensor is equipped with a vibration-resistant and bend-resistant "Robot Cable," making it ideal for moving parts like robotic arms or CNC heads. * **Built-in Protection:** It includes noise immunity circuits and protection against power supply reverse polarity. * **Compact Form Factor:** The R-shape (Right-angle) mounting allows for low-profile installation in tight mechanical assemblies. --- ### 4.
