## Electronic Specifications: R10S-R1W2-DC The **R10S-R1W2-DC** is a specific model within the R10 series of electromagnetic relays, commonly manufactured by TE Connectivity (formerly Potter & Brumfield). It is a low-profile, versatile relay used in signaling and general-purpose switching. ### 1. Model Breakdown Understanding the suffix codes helps identify the specific electronic characteristics of this part: | Code Segment | Description | Specific Detail | | :--- | :--- | :--- | | **R10** | Series Name | Multi-pole, relay family | | **S** | Sensitivity | Super-sensitive (High sensitivity coil) | | **R1** | Contact Arrangement | 1 Form C (SPDT) | | **W2** | Contact Rating | Low level to 2A switching | | **DC** | Input Type | Direct Current Coil | --- ### 2. Core Technical Specifications #### Coil Data (Input) The "S" designation indicates a sensitive coil designed for low-power operation. * **Pick-up Power:** Generally requires very low milliwatts (mW) to actuate. * **Voltage:** Typically operates within standard DC ranges (specified by the final voltage suffix, e.g., 5V, 12V, or 24V). * **Coil Resistance:** Higher than standard R10 models to accommodate lower current draw. #### Contact Data (Output) * **Contact Form:** 1 Form C (Single Pole Double Throw - SPDT). * **Contact Material:** Usually gold-plated silver or similar alloys to handle low-level signals. * **Current Rating:** * **Max Switching:** 2 Amperes. * **Min Switching:** Often rated for dry circuit (micro-amps) due to "W" contact type. * **Voltage Rating:** Up to 120VAC or 28VDC (load dependent). --- ### 3. Physical & Environmental Features * **Packaging:** Clear plastic dust cover (typically). * **Mounting:** Through-hole PCB mounting or plug-in socket. * **Terminals:** Solder-lug or PCB pins. * **Dielectric Strength:** 500V rms between contacts; 1000V rms between coil and contacts. --- ### 4. Application Use Cases Because of the **Sensitive (S)** coil and **SPDT (R1)** configuration, this part is ideal for: 1. **Battery Powered Devices:** Where minimizing current draw is critical. 2. **Logic-Level Interface:** Driving high-power circuits directly from microcontrollers or low-power transistors. 3. **Telecommunications:** Signal switching where low contact resistance and high reliability are required.
