The **M8TS1-299-R/SK** is a high-precision connector assembly, typically used in industrial automation, sensor technology, and signal transmission. It follows the standard M8 circular connector architecture but features specific shielding and mounting characteristics denoted by its suffixes. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Connector Size** | M8 (8mm metric thread) | | **Termination Type** | Solder or Screw-terminal (Model dependent) | | **Mounting Style** | Panel Mount / Rear Mount | | **Contact Plating** | Gold (Au) over Nickel (Ni) | | **Ingress Protection** | IP67 / IP68 (when mated) | | **Shielding** | Fully Shielded (360°) | | **Voltage Rating** | 30V - 60V AC/DC | | **Current Rating** | 1.5A - 4A | --- ### Component Breakdown #### 1. Housing and Shell The shell is usually constructed from **Nickel-plated brass** or stainless steel. The "SK" suffix often refers to a specific "Shielded Kit" or "Shielded Keyway" configuration, ensuring electromagnetic interference (EMI) protection for sensitive data signals. #### 2. Insulator (Dielectric) The internal core is made of high-performance engineering plastics (such as PA66 or PBT). This provides high insulation resistance (typically $>100 M\Omega$) and maintains structural integrity under thermal stress. #### 3. Contact Pins * **Material:** Phosphor bronze or brass base. * **Plating:** Gold plating ensures low contact resistance and prevents oxidation, which is critical for low-voltage sensor signals. #### 4. Sealing (O-Rings) The "R" in the part number often signifies a specific **Rear-mount** configuration or a specific **Rubber** O-ring material (like Viton or NBR) that provides the IP67 waterproof rating. --- ### Application Use Cases 1. **Industrial Sensors:** Connection of proximity switches, photoelectric sensors, and encoders. 2. **Actuators:** Powering small valves and motor starters in tight spaces. 3. **Data Bus:** Used in EtherCAT, Profibus, or CANopen networks where compact, shielded connections are required. 4. **Robotics:** High-vibration environments where a threaded locking mechanism is superior to snap-on connectors. ---
