The **M8YV-4W44-R** is a specific part number belonging to the **M8 Series** of industrial circular connectors, commonly used in automation, sensor integration, and industrial control systems. --- ## 1. Technical Specifications The part number typically breaks down into several key electronic and mechanical attributes. Here is the technical overview: | Feature | Specification | | :--- | :--- | | **Connector Type** | M8 Circular Connector | | **Number of Poles** | 4-Pin | | **Gender** | Female (often indicated by 'V' or internal coding) | | **Orientation** | Right-Angle (R) | | **Mounting Type** | PCB Mount (Through-hole) or Wire-lead (Series dependent) | | **Contact Plating** | Gold over Nickel (standard for reliability) | | **Rated Voltage** | 30V AC/DC | | **Rated Current** | 3A - 4A per contact | --- ## 2. Key Component Features The electronic parts within this assembly are designed for harsh environments: ### A. Contact Interface * **Gold-Plated Pins:** The 4-pin configuration utilizes gold plating to ensure low contact resistance and prevent oxidation in industrial environments. * **Mechanical Keying:** Features "A-Coding" (standard for sensors/actuators) to prevent incorrect mating with different voltage sources. ### B. Material Composition * **Housing:** Usually made of high-temperature thermoplastic (e.g., PBT or PA66) to withstand soldering temperatures and mechanical stress. * **Shielding:** The "-R" variant often indicates a specific shielding or orientation configuration to reduce Electromagnetic Interference (EMI) in data transmission. ### C. Environmental Protection * **IP Rating:** When mated, these connectors typically achieve **IP67** or **IP68** ratings, making them dust-tight and waterproof. --- ## 3. Typical Applications The M8YV-4W44-R is primarily found in the following electronic systems: 1. **Industrial Sensors:** Connecting proximity switches, photoelectric sensors, and ultrasonic transducers to a PLC. 2. **Actuators:** Powering small solenoid valves or indicators. 3. **Robotic Arms:** Compact signal routing where space is limited and right-angle connections are necessary to prevent cable strain. 4. **Fieldbus Systems:** Used in basic I/O link modules.
