The **WJFX-AD2-R/Q** is a specific technical designation typically associated with **WJFX series waterproof microswitches** or specialized electromechanical components often used in automotive and industrial control systems. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Component Overview This part is a **sealed microswitch** designed for high reliability in harsh environments. The suffix "R/Q" usually denotes specific terminal configurations or compliance standards (such as REACH/RoHS or specific automotive grading). | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Sealed Microswitch / Snap Action Switch | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Protection Rating** | IP67 (Dust-tight and Water-resistant) | | **Operating Temperature** | -40°C to +85°C | | **Mechanical Life** | 500,000 to 1,000,000 cycles | --- ### 2. Electrical Specifications These parameters define the safe operating limits for the switch contacts to prevent arcing or premature failure. | Parameter | Value | | :--- | :--- | | **Rated Voltage (DC)** | 12V DC - 24V DC | | **Rated Current** | 0.1A to 3A (Load dependent) | | **Contact Resistance** | < 100 mΩ (Initial) | | **Insulation Resistance** | > 100 MΩ (at 500V DC) | | **Dielectric Strength** | 500V AC (50/60Hz for 1 minute) | --- ### 3. Key Electronic Features * **Sealing Technology:** The "WJFX" series utilizes an internal silicone rubber seal and epoxy resin potting at the wire/terminal exit point to ensure the internal contacts are protected from moisture and oxidation. * **Snap-Action Mechanism:** Uses a high-precision spring mechanism that ensures fast contact transfer regardless of the speed of the physical actuator, reducing electrical arcing. * **Gold-Plated Contacts (Optional):** Often used in the "AD2" variants to handle low-current signals (logic levels) without surface oxidation interference. --- ### 4. Typical Applications The WJFX-AD2-R/Q is commonly found in environments where the component is exposed to elements: 1. **Automotive:** Door latches, seatbelt sensors, and trunk releases. 2. **Industrial:** Limit switching in CNC machines or outdoor security gates. 3. **Appliances:** Safety interlocks in washing machines or outdoor HVAC units. --- ### 5. Terminal and Wiring Configuration Depending on the "R/Q" designation, the part usually features: * **Pre-wired leads:** Waterproof wires factory-soldered and potted. * **PCB Terminals:** Right-angle or straight pins for direct board mounting. * **Solder Terminals:** Standard lugs for manual wiring.
