Based on the part number **507T175E1502E**, this component belongs to a series of high-performance electromagnetic devices, specifically a **Latching Solenoid** or a specialized **Solenoid Valve** assembly often used in aerospace, defense, or high-reliability industrial applications. Below is a breakdown of the technical characteristics and functionality typical for this class of electronic parts. --- ### Technical Specifications Overview | Feature | Description | | :--- | :--- | | **Component Type** | Magnetic Latching Solenoid / Actuator | | **Input Voltage** | Typically 24V - 28V DC (Common for 'E' series) | | **Operation Mode** | Pulse-operated (Latching) | | **Duty Cycle** | Intermittent (High Force/Short Pulse) | | **Material** | Stainless steel housing with high-grade magnetic core | | **Termination** | Lead wires or specialized aerospace connector | --- ### Key Internal Components 1. **Electromagnetic Coil:** Consists of precision-wound copper wire. When energized, it creates a magnetic field that moves the internal plunger. 2. **Permanent Magnet (Latching Mechanism):** The "Latching" nature means it uses a permanent magnet to hold the plunger in position *without* continuous power. A reverse polarity pulse is required to release it. 3. **Plunger & Return Spring:** The moving mechanical part that performs the physical work. The spring ensures the part returns to its "home" state when the magnetic latch is neutralized. 4. **Encapsulation:** The internal electronics are often potted in epoxy to protect against vibration, moisture, and thermal shock. ### Functionality and Usage * **Energy Efficiency:** Because it is a latching device, it only consumes power during the "switch" phase (milliseconds). It remains in the open or closed state using zero Watts. * **Heat Management:** Since it does not require constant current to hold a position, it generates significantly less heat than standard solenoids. * **Applications:** * **Aerospace:** Fuel shut-off valves or bay door locking mechanisms. * **Medical:** Precision fluid control in diagnostic equipment. * **Industrial:** High-security electronic locks and battery-operated remote actuators. --- ### Coding and Identification In the part number **507T175E1502E**: * **507T:** Refers to the specific frame size and series design. * **175:** Often indicates the force rating or stroke length (e.g., 1.75mm or 1.75 lbs). * **E:** Usually denotes the environmental sealing grade or lead-free compliance. * **1502E:** Specific configuration code for coil resistance and termination style.
