## Technical Overview of the FTS-2E-R The **FTS-2E-R** is a specific electronic component primarily associated with **RF (Radio Frequency) switching** and signal routing. Based on industry standards, this part number typically refers to a high-performance, sub-miniature electromagnetic relay or a specialized RF coaxial switch assembly. --- ### Key Technical Specifications The following table outlines the general electronic characteristics associated with the FTS series: | Parameter | Typical Specification | | :--- | :--- | | **Component Type** | Electromechanical Relay / RF Switch | | **Contact Configuration** | DPDT (Double Pole Double Throw) | | **Operating Voltage** | Usually 12V or 24V DC (Model dependent) | | **Frequency Range** | DC to 2.5 GHz+ (varies by variant) | | **Impedance** | 50 Ohms (Standard for RF) | | **Mounting Type** | Through-hole or SMD | --- ### Internal Electronic Components The "R" suffix often indicates a **Lead-Free (RoHS Compliant)** version or a specific **Latching** mechanism. Internally, the device consists of: 1. **Solenoid Coil:** A copper wire winding that creates a magnetic field when energized. 2. **Armature:** A moving metal part that responds to the magnetic field to bridge contacts. 3. **Gold-Plated Contacts:** Used to ensure low contact resistance and prevent oxidation, which is critical for maintaining signal integrity in high-frequency applications. 4. **Damping Spring:** Ensures the contacts return to their original position once power is removed (in non-latching versions). --- ### Typical Applications Because of its electronic design, the FTS-2E-R is commonly found in: * **Telecommunications:** Signal routing in base stations. * **Test & Measurement:** Switching between different signal paths in oscilloscopes or signal generators. * **Medical Equipment:** High-reliability switching in diagnostic imaging. * **Aeronautics:** Communication bus switching where low insertion loss is mandatory. --- ### Schematic Representation ```text [ Coil ] +----( )----+ | | (COM1) (COM2) / / (NC1) (NO1) (NC2) (NO2) ``` * **NC:** Normally Closed * **NO:** Normally Open * **COM:** Common terminal ---
