The **M8YV-Z44-R/BL** refers to a high-performance **M8 Industrial Circular Connector** assembly, typically used in automation, sensor integration, and robotics. This specific part number follows a modular coding system used by manufacturers (often associated with brands like **Misumi** or similar industrial suppliers). Below is a breakdown of its electronic and mechanical specifications: ### 1. Part Number Specification Breakdown | Component Segment | Description | Detail | | :--- | :--- | :--- | | **M8** | Connector Type | Standardized M8 circular thread interface. | | **YV** | Cable Entry/Style | Often denotes a Y-junction or a specific PVC/PUR jacket material. | | **Z44** | Pin Configuration | 4-Pin Female/Male arrangement (Standard A-Coding). | | **R/BL** | Color/Orientation | **R** usually denotes Right-Angle; **BL** typically indicates Black cable/housing. | --- ### 2. Technical Specifications These connectors are designed to operate in harsh industrial environments. * **Rated Voltage:** 30V AC / 30V DC (Standard for M8 4-pin). * **Rated Current:** 3A to 4A per contact. * **Insulation Resistance:** $\geq 100\, M\Omega$. * **Contact Resistance:** $\leq 10\, m\Omega$. * **IP Rating:** Typically **IP67** or **IP68** (Waterproof and Dust-tight when mated). * **Operating Temperature:** $-25^\circ \text{C}$ to $+80^\circ \text{C}$. --- ### 3. Pinout Mapping (Standard 4-Pin) In industrial automation (IEC 61076-2-104), the wiring for a 4-pin M8 connector usually follows this color code: | Pin Number | Wire Color | Common Function | | :--- | :--- | :--- | | 1 | Brown | +VCC (Power) | | 2 | White | Digital Output 2 / Analog Signal | | 3 | Blue | GND (Common) | | 4 | Black | Digital Output 1 (Switching) | --- ### 4. Typical Applications * **Proximity Sensors:** Connection for inductive or capacitive sensors. * **Small Actuators:** Powering micro-solenoids or small DC motors. * **I/O Boxes:** Connecting field devices to a centralized PLC (Programmable Logic Controller) block. * **Machine Vision:** Low-voltage power supply for compact industrial cameras. --- ### 5. Maintenance and Installation Tips ```bash # Installation Checklist: 1. Ensure the O-ring is present to maintain IP67 rating. 2. Align the internal "key" before tightening to prevent bent pins. 3. Tighten to recommended torque (usually 0.4 Nm) to avoid thread stripping. ```
