The **M2UDS-K4W-R/N** belongs to the **M2UDS series** of high-speed, high-resolution digital indicator units manufactured by **Magnescale** (formerly Sony Manufacturing Systems). These units are primarily used in precision measurement applications. Below is a breakdown of its electronic components, specifications, and features. --- ### 1. Technical Specifications The "K4W" designation typically refers to a specific input/output configuration and physical size. | Parameter | Specification Details | | :--- | :--- | | **Compatible Probes** | Magnescale DK series (DK800, DK10, etc.) | | **Resolution** | Selectable (usually up to 0.1 μm or 0.5 μm) | | **Output Type** | BCD (Binary Coded Decimal) or RS-232C (Depending on exact module) | | **Power Supply** | +12V to +24V DC | | **Display Type** | 7-segment green LED (High visibility) | | **Mounting Style** | Panel Mount (DIN size) | --- ### 2. Key Electronic Features #### A. Signal Processing Engine The unit contains high-speed interpolation circuitry. It converts the analog sine/cosine signals from a Magnescale probe into digital pulses, allowing for sub-micron measurement accuracy. #### B. Comparative Outputs (Go/No-Go) The "R/N" in the model name often refers to the **Comparator Logic**: * **Relay/Open Collector Outputs:** Used for automated quality control. It provides signals for: * **High (H):** Measurement exceeds upper limit. * **Go (G):** Measurement is within tolerance. * **Low (L):** Measurement is below lower limit. #### C. Connectivity Ports The back of the unit features several electronic interfaces: 1. **Probe Input:** A multi-pin connector for the Magnescale sensor. 2. **I/O Terminal Block:** For external Reset, Peak Hold, and Preset functions. 3. **Data Output:** Used to send measurement data to a PLC (Programmable Logic Controller) or PC. --- ### 3. Usage Context The M2UDS-K4W-R/N is designed for industrial environments where electronic noise is common. It features: * **High Noise Immunity:** Shielded circuitry to prevent interference from motors or high-voltage lines. * **Peak Hold Functions:** Electronics capable of capturing Maximum, Minimum, and Peak-to-Peak (TIR) values digitally. --- ### 4.
