The **M8TS1-244-R/SK** is a high-performance, shielded M8 connector assembly typically used in industrial automation for sensor and actuator connectivity. Below is a detailed breakdown of its electronic and mechanical specifications. --- ## 1. Technical Specifications This component is designed to handle power and signal transmission in harsh environments where space is limited. | Feature | Specification | | :--- | :--- | | **Connector Type** | M8 Series | | **Gender** | Female (Standard Socket) | | **Number of Pins** | 4-Pin | | **Coding** | A-Coding (Standard for sensors/DC power) | | **Rated Voltage** | 30V AC / 36V DC | | **Rated Current** | 3A - 4A (depending on wire gauge) | | **Contact Resistance** | ≤ 5 mΩ | | **Insulation Resistance** | ≥ 100 MΩ | | **IP Rating** | IP67 / IP68 (when mated) | --- ## 2. Key Electronic Components & Construction The "R/SK" suffix usually denotes specific shielding and termination characteristics: ### A. Contact Material The pins are typically made of **Phosphor Bronze or Brass** with **Gold (Au) plating** over Nickel. The gold plating ensures: * Minimal signal loss. * Prevention of oxidation in humid industrial settings. * High mating cycle durability (typically >100 cycles). ### B. Shielding (EMC Protection) The "SK" designation often refers to **Shielded (Schirmung)**. * **Function:** It includes a 360° shielding wrap to protect data signals from Electromagnetic Interference (EMI) caused by nearby motors or high-voltage cables. * **Grounding:** The shield is electrically connected to the coupling nut to ensure continuity to the machine ground. ### C. Insulation & Housing * **Insert:** PA66 or TPU (Thermoplastic Polyurethane), which offers high dielectric strength. * **Coupling Nut:** Nickel-plated brass, providing a secure mechanical lock and vibration resistance. --- ## 3. Pin Configuration (A-Coding) For a 4-pin M8 connector, the standard wiring follows the industrial color code: | Pin Number | Wire Color | Typical Function | | :--- | :--- | :--- | | **1** | Brown | Positive (+24V DC) | | **2** | White | Second Signal (I/O) | | **3** | Blue | Negative (0V / Ground) | | **4** | Black | Primary Signal (Switching) | --- ## 4. Common Applications * **Proximity Sensors:** Inductive and capacitive sensors. * **Actuators:** Small solenoid valves or indicators. * **Fieldbus Systems:** Distributed I/O modules in factory automation. * **Robotics:** Compact signal routing in robotic arms.
