The **G6WK-1F-R** is a specific model of a subminiature, surface-mount (SMD) signal relay manufactured by **Omron Electronic Components**. It is widely recognized for its high sensitivity and its unique **latching (bistable)** mechanism. --- ## 1. Core Specifications Below are the primary technical parameters for the G6WK-1F-R series: | Parameter | Specification | |:---|:---| | **Relay Type** | 2-Winding Latching | | **Contact Form** | SPDT (1 Form C) | | **Rated Load** | 0.5 A at 125 VAC; 1 A at 30 VDC | | **Max Switching Voltage** | 125 VAC, 60 VDC | | **Coil Voltage (Typical)** | 3V, 4.5V, 5V, 6V, 9V, 12V, or 24V DC | | **Power Consumption** | Approx. 360 mW | | **Mounting Type** | Surface Mount (SMD) | | **Terminal Shape** | F-shape (Gull-wing) terminals | --- ## 2. Key Internal Components & Features ### A. The 2-Winding Latching Mechanism Unlike a standard "monostable" relay that requires constant power to stay active, the G6WK-1F-R is a **2-winding latching** relay. * **Set Coil:** Pulsing this coil moves the armature to the "Set" position. * **Reset Coil:** Pulsing this coil moves the armature back to the "Reset" position. * **Benefit:** The device remains in its last state even if power is completely removed, making it ideal for battery-powered or energy-efficient devices. ### B. Contact Materials The contacts are typically made of **Silver (Ag) alloy with Gold (Au) plating**. This dual-layer approach ensures: * High conductivity. * Resistance to oxidation/corrosion over time. * Reliable switching for low-level signals (dry circuits). ### C. Construction & Packaging * **Fully Sealed:** The plastic housing is sealed to protect the internal mechanical parts from dust and soldering flux. * **SMT Terminals:** Designed for automated pick-and-place assembly. The "1F" in the part number specifically denotes the surface-mount terminal style. --- ## 3. Pinout Configuration While you should always consult the specific datasheet for your voltage variant, the standard G6WK-1F-R layout follows this logic: ```text Top View (Approximate Layout) +-----------------------+ | (1) (2) (3) (4) | <-- Coil Terminals (Set/Reset) | | | (8) (7) (6) (5) | <-- Contact Terminals (COM, NO, NC) +-----------------------+ ``` --- ## 4. Typical Applications Due to its small footprint and latching nature, it is frequently used in: 1. **Telecommunications:** Signal switching in PBX or modems. 2. **Test & Measurement:** Oscilloscopes and automated test equipment (ATE). 3. **Medical Equipment:** Portable diagnostic devices where power saving is critical. 4. **Security Systems:** Control panels that must maintain status during power failures.
