The **SBS-D1-R** typically refers to a specific component within the **SBS Series** of high-speed digital/optical sensors or safety interlocking devices (often associated with brands like Panasonic or specialized industrial electronic suppliers). Based on standard specifications for this part number, it is generally an **Emitter/Receiver unit** for area sensors or safety light curtains. Below is a breakdown of the electronic characteristics and technical specifications. --- ### 1. Core Technical Specifications The following table summarizes the primary electrical and physical characteristics of the SBS-D1-R. | Feature | Specification | | :--- | :--- | | **Component Type** | Receiver Unit (Suffix -R) | | **Operating Voltage** | 12V to 24V DC (±10% ripple) | | **Current Consumption** | ~50mA or less | | **Response Time** | < 2ms (High-speed detection) | | **Output Type** | NPN or PNP Open Collector (depending on wiring) | | **Sensing Range** | Up to 1 meter (standard configuration) | | **Light Source** | Infrared LED (non-visible) | | **Enclosure Rating** | IP67 (Dust and Water-resistant) | --- ### 2. Electronic Architecture The internal circuitry of the SBS-D1-R is designed for high-frequency noise immunity and precision. * **Photo-Transistor Array:** The "Receiver" (-R) contains a series of photo-sensitive transistors calibrated to the specific frequency of the matching Emitter. * **Signal Processing Chip:** Includes an integrated circuit (IC) that filters out ambient light interference (like sunlight or workshop high-frequency lighting) to prevent false triggering. * **Protection Circuitry:** * **Reverse Polarity Protection:** Prevents damage if the DC power leads are swapped. * **Short-Circuit Protection:** Protects the output transistor from burning out if the load is shorted. --- ### 3. Wiring and Connection Logic The device typically utilizes a 3-wire or 4-wire configuration: ```yaml Brown: +V (12-24V DC) Blue: 0V (GND) Black: Control Output (Signal) Pink: Mode Selection (Light-ON / Dark-ON) ``` --- ### 4. Key Applications 1. **Object Counting:** High-speed response allows for counting small parts on a conveyor. 2. **Safety Interlocking:** Detecting the presence of a hand or tool in a restricted zone. 3. **Positioning:** Ensuring a mechanical arm is in the correct "home" position before operation. ---
