## ADN-112-R: Electronic Specifications and Components The **ADN-112-R** is a specific model of a **Compact Pneumatic Cylinder** manufactured by **Festo**. While it is primarily a mechanical/pneumatic actuator, its "electronic" aspect refers to its compatibility with position sensing and control integration. --- ### 1. Key Technical Specifications The following table outlines the physical and functional parameters that dictate how electronic sensors interact with this part. | Parameter | Specification | | :--- | :--- | | **Bore Size** | 12 mm | | **Stroke Length** | Typically variable (check specific suffix) | | **Cushioning** | P: Flexible cushioning rings/plates at both ends | | **Position Detection** | Via proximity sensor (integrated slot) | | **Operating Pressure** | 1.0 ... 10 bar | | **Piston-rod End** | Male thread (R-variant) | --- ### 2. Electronic Position Sensing The ADN-112-R is designed with a **built-in permanent magnet** on the internal piston. This allows for electronic feedback using the following components: #### A. Proximity Sensors (T-Slot) The cylinder body features an integrated **T-slot**. Electronic sensors (Reed or Magnetoresistive) are inserted here to detect the piston's position. * **Sensor Type:** SMT-8M-A (Magnetoresistive) or SME-8M (Reed switch). * **Connection:** Usually M8 or M12 plug, or open cable ends. * **Output:** PNP, NPN, or Contacting. #### B. Electronic Control Interface * **Solenoid Valves:** To actuate the ADN-112-R, it must be paired with an electronic solenoid valve (e.g., Festo VUVG series). * **Voltage:** Common control voltages are 24V DC. * **Logic:** The proximity sensors provide inputs to a PLC (Programmable Logic Controller) to confirm if the cylinder is "Extended" or "Retracted." --- ### 3. Electronic Components Compatibility List If you are building a system around the ADN-112-R, these are the electronic accessories required: | Component Type | Part Number (Example) | Function | | :--- | :--- | :--- | | **Proximity Sensor** | `SMT-8M-A-PS-24V-E` | Detects end-position via magnet. | | **Connecting Cable** | `NEBU-M8G3-K-2.5-LE3` | Connects sensor to the controller. | | **Solenoid Valve** | `VUVG-L10-B52-T-M7` | Electrically controls air flow to move the piston. | --- ### 4. Summary of "R" Variant Features The **-R** in the part number specifically denotes the **Piston rod with male thread**. While this is a mechanical feature, it impacts the electronic setup by determining the mounting of the load, which may affect the cycle time and the sensitivity required for the electronic sensors.
