The **REBS-BF-R** is an electronic component primarily associated with industrial automation and control systems, specifically within the realm of sensor technology or safety relay modules (often used in elevator control systems or automated machinery). Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. Overview and Function The REBS-BF-R is typically categorized as a **Bi-Stable Reed Sensor** or a **Magnetic Proximity Switch**. It is designed to change its output state based on the presence of a magnetic field and maintain that state until an opposite magnetic pole is detected. | Feature | Description | | :--- | :--- | | **Component Type** | Bi-Stable Magnetic Sensor | | **Contact Type** | Changeover (SPDT - Single Pole Double Throw) | | **Switching Logic** | Bi-stable (Latching) | | **Housing Material** | Rectangular plastic (usually PA66 or similar) | --- ### 2. Electrical Specifications These parts are engineered to handle signaling loads rather than direct power loads. | Parameter | Typical Value | | :--- | :--- | | **Max Switching Voltage** | 230V AC/DC | | **Max Switching Current** | 1.0 A | | **Max Switching Capacity** | 60 VA / 60 W | | **Contact Resistance** | < 150 mΩ | | **Operating Temperature** | -20°C to +70°C | --- ### 3. Key Electronic Characteristics * **Bi-Stable Operation:** Unlike monostable switches that return to a "default" state when the magnet is removed, the REBS-BF-R "remembers" its last state. * *North Pole:* Switches to State A. * *South Pole:* Switches to State B. * **Reed Technology:** The core consists of a hermetically sealed glass tube containing metal reeds. This protects the contacts from oxidation, dust, and moisture, making it highly reliable in harsh industrial environments. * **Protection Rating:** Usually rated **IP67**, meaning it is dust-tight and can withstand immersion in water, which is critical for elevator shafts or outdoor machinery. --- ### 4. Typical Wiring Diagram (Conceptual) The device usually features a three-wire configuration: ```c [Common (COM)] ------- (Wire 1: Black) | +----[Normally Open (NO)] --- (Wire 2: Blue) | +----[Normally Closed (NC)] -- (Wire 3: Brown) ``` --- ### 5. Common Applications 1. **Elevator Position Sensing:** Used to detect floor levels or limit stops. 2. **Industrial Gates:** Detecting open/closed status for heavy-duty security gates. 3. **Conveyor Systems:** Counting items or detecting the position of mechanical arms. ---
