### Overview of B3W-9010-R2N The **B3W-9010-R2N** is a specific model within the Omron B3W-9 series. It is an **Illuminated Tactile Switch** designed for through-hole mounting on Printed Circuit Boards (PCBs). This component combines a physical momentary switch with an integrated LED, allowing for compact user-interface designs. --- ### Key Specifications | Feature | Specification | | :--- | :--- | | **Switch Type** | Tactile Switch (Momentary) | | **Illumination Color** | Red (indicated by 'R' in the part number) | | **LED Configuration** | 2 LEDs (integrated) | | **Operating Force** | 1.57 N (approx. 160gf) | | **Contact Form** | SPST-NO (Single Pole, Single Throw - Normally Open) | | **Termination Style** | Through-hole (PCB pins) | | **External Dimensions** | 10mm x 10mm | | **Cap Style** | Square Cap | --- ### Technical Characteristics #### 1. Mechanical Life The switch is designed for high durability, typically rated for a minimum of **1,000,000 operations**. This makes it suitable for high-traffic interfaces. #### 2. Sealing Structure The B3W-9 series features a sealed construction (equivalent to **IP67**). This prevents dust and liquid ingress, allowing the component to be submersed during the soldering/washing process and ensuring reliability in harsh environments. #### 3. Electrical Ratings * **Switching Capacity:** 1 to 50 mA, 3 to 24 VDC. * **Insulation Resistance:** 100 MΩ minimum (at 250 VDC). * **Contact Resistance:** 100 mΩ maximum. --- ### Pin Configuration and Wiring The device typically has 6 pins: * **4 Pins** for the switch mechanism (arranged in pairs for stability). * **2 Pins** dedicated to the LEDs (Anode and Cathode). ```text Pin Layout Diagram (Top View): [ 1 ] --- [ 2 ] (Switch Contacts) [ L ] --- [ L ] (LED Anode/Cathode) [ 3 ] --- [ 4 ] (Switch Contacts) ``` --- ### Common Applications * **Control Panels:** Industrial machinery and automation controls. * **Medical Equipment:** Devices requiring a sealed, easy-to-clean interface. * **Consumer Electronics:** High-end audio equipment or office peripherals where status indication is needed on the button itself.
