The **FPA-15-R** is a specific electronic component commonly used in industrial automation, specifically within the **Festo** product ecosystem. It is a **flat plate adapter** used primarily for mounting or interfacing pneumatic and electronic sensing equipment. Below is a breakdown of its technical specifications and electronic context. --- ### 1. General Specifications The FPA-15-R is part of the mounting accessory family for linear actuators or sensors. It serves as the physical bridge between the mechanical movement and the electronic feedback system. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Festo | | **Part Number** | 151556 (typically) | | **Material** | High-grade Aluminum alloy / Galvanized Steel | | **Component Type** | Mounting Adapter Plate | | **Compatibility** | DFM / SLT / DNC series actuators | ### 2. Electronic Integration While the plate itself is a mechanical mounting part, its "electronic" relevance lies in how it facilitates sensor integration: * **Sensor Mounting:** The "R" in the suffix often denotes a specific orientation or compatibility with **Proximity Sensors** (Reed switches or Hall-effect sensors). * **Signal Accuracy:** By providing a rigid, vibration-resistant mount, the FPA-15-R ensures that electronic sensors maintain a consistent distance from the magnetic piston, preventing "false triggers" or signal loss. * **Switching Sensitivity:** It is designed to be non-magnetic (aluminum) so that it does not interfere with the magnetic flux required to trigger electronic position transmitters. ### 3. Structural Breakdown The component consists of several key sub-parts required for a complete electronic assembly: 1. **Base Plate:** Precision machined to align with the axis of the actuator. 2. **Mounting Holes:** Specifically spaced for M3 or M4 screws, standard for small-scale electronic sensor brackets. 3. **Alignment Pins:** Used to ensure the sensor's electronic "sweet spot" is perfectly centered over the target. --- ### 4. Typical Application Workflow 1. **Mechanical Attachment:** The FPA-15-R is bolted to a pneumatic slide. 2. **Sensor Installation:** An electronic proximity sensor (e.g., Festo SMT or SME series) is attached to the plate. 3. **Wiring:** The sensor cables are routed via the plate's cable management notches to a PLC (Programmable Logic Controller) or I/O link master.
