The **MEH72ZAD-R** is a specific model of an **Electric Linear Actuator** (often categorized as a motorized cylinder or slide) manufactured by **Oriental Motor**. This part is commonly used in precision industrial automation for controlled linear motion. --- ## 1. Technical Specifications The "MEH" series refers to the compact linear actuator line. Below is a breakdown of the typical electronic and mechanical characteristics for this specific part number: | Feature | Specification | | :--- | :--- | | **Motor Type** | AZ Series (AC Input) | | **Control Method** | Built-in Controller (Network compatible) or Pulse Input | | **Lead (Screw Pitch)** | 6 mm | | **Stroke Length** | 200 mm (indicated by 'Z' in specific configurations) | | **Max Payload** | Horizontal: ~30kg / Vertical: ~10kg (variable by speed) | | **Encoder Type** | ABZO Mechanical Absolute Sensor | --- ## 2. Key Electronic Components ### A. The ABZO Sensor (Absolute Encoder) The most critical electronic feature of the MEH72ZAD-R is the **ABZO mechanical absolute sensor**. - **Battery-less:** It does not require a backup battery to retain position data. - **Home Position:** Because it is an absolute sensor, the actuator "knows" its location immediately upon power-up, eliminating the need for a return-to-home sequence using external sensors. ### B. Motor Integration The unit utilizes a **stepper motor base** (part of the αSTEP AZ Series) but operates with the precision of a servo. - **Closed-loop control:** The internal electronics monitor the motor's position and automatically correct for any potential "missed steps" under high loads. - **Heat Management:** The electronics are tuned to reduce current when the motor is stopped, minimizing heat generation. ### C. Connection and Wiring The suffix `-R` often denotes specific cable or connector orientations (often "Right" side lead or "Robot" cable flexibility). - **Power Input:** Typically requires a matching driver (AZD-A, AZD-C, or AZD-K) which converts AC line voltage to the DC pulses needed for the actuator. - **I/O Signals:** The electronic interface supports limit sensors, stop signals, and position completion signals. --- ## 3. Application Use Cases Due to its electronic precision, this part is used in: 1. **Pick-and-Place:** High-speed movement between electronic assembly stations. 2. **Pressing Operations:** Controlled force and position for fitting small electronic components. 3. **Automated Testing:** Moving probes or cameras to exact coordinates for QC.
