The **R10-R2X3DC** is a specific model within the **R10 Series** of electromechanical relays manufactured by **TE Connectivity (formerly P&B / Potter & Brumfield)**. This part is a versatile, multi-pole relay widely used in industrial control panels, medical equipment, and telecommunications. Below is a detailed breakdown of its electronic specifications and parts. --- ## 1. Part Number Decoder Understanding the "R10-R2X3DC" nomenclature is essential to identifying its capabilities: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **R10** | Series | Standard R10 Cradle Relay Series | | **R2** | Mounting/Termination | Plug-in/Solder terminals with #3-48 tapped mounting hole | | **X** | Contact Arrangement | 2 Form C (DPDT - Double Pole Double Throw) | | **3** | Contact Material | Fine Silver, Gold Flashed (Standard rating) | | **DC** | Coil Voltage Type | Direct Current (Voltage specific, e.g., 5V, 12V, 24V) | --- ## 2. Key Electronic Specifications The R10 series is known for its high sensitivity and modular contact arrangements. ### A. Contact Data * **Arrangement:** 2 Form C (DPDT). This means it has two separate circuits, each with a Common (COM), Normally Open (NO), and Normally Closed (NC) pin. * **Current Rating:** Typically up to **2 Amps** or **5 Amps** depending on the specific load voltage. * **Material:** Fine Silver (Gold flashed) to prevent oxidation and ensure low contact resistance at low signal levels. ### B. Coil Data * **Voltage:** DC operated. (Common variations include 6VDC, 12VDC, 24VDC, and 48VDC). * **Power Consumption:** Approximately **500mW to 1.0W** depending on the sensitivity of the specific coil winding. * **Duty Cycle:** Continuous. ### C. Mechanical/Insulation * **Dielectric Strength:** ~1,000V rms between open contacts; ~1,500V rms between contact sets and coil. * **Temperature Range:** -55°C to +75°C. --- ## 3. Physical Components The relay consists of four primary internal electronic/mechanical assemblies: 1. **The Coil:** A copper wire winding around a core. When energized, it creates an electromagnetic field. 2. **The Armature:** A hinged metal piece that is pulled toward the coil when magnetized. 3. **The Contacts:** The switching mechanism. In a "2 Form C" setup, there are six contact points total. 4. **The Dust Cover:** A clear polycarbonate (plastic) shell that protects the internal contacts from environmental contaminants while allowing visual inspection of operation. --- ## 4. Common Applications * **Signal Switching:** Low-level audio or data switching. * **Logic Isolation:** Separating a low-power control circuit (like a microcontroller) from a higher-power load. * **Industrial Sequencing:** Used in older machinery for timing and logic operations. ---
