5. Bus Line Shorting/Termination
- Requirement: Short or terminate bus lines for signal stability
- Recommended Model: 2799694 (SUBCON-SHORT-SCREW)
- Key Reason: Screw-type design for secure shorting/termination of bus lines
Core Advantages
- Multi-Bus Compatibility: Supports PROFIBUS/CAN/ARCNET, covering mainstream industrial bus needs
- Rugged Interfaces: M12/PG variants offer IP67 protection for field-installed devices
- Flexible Mounting: Angled (35°/90°) and straight options fit space-constrained installations
- Signal Stability: EMI/RFI shielding ensures interference-free communication in noisy environments
- Industrial-Grade Durability: Wide temperature range (-25℃~70℃) and robust construction resist harsh conditions
- Standardized Design: Complies with industrial interface standards for universal compatibility
- Easy Installation: Tool-free mating (some variants) and DIN rail/panel-mount options simplify deployment
Installation & Usage Notes
- Bus Protocol Matching: Select models based on the target bus protocol (e.g., CAN models for CAN bus systems)
- Interface Compatibility: Verify device interface (M12/PG/AX) matches the connector type
- Cable Selection: Use shielded industrial cables to maximize signal integrity and EMI protection
- Mounting Torque: Tighten M12/PG connectors to recommended torque (0.5~0.8Nm) for secure connections
- Cable Routing: Avoid routing bus cables near power lines to reduce cross-interference
- Termination: Use appropriate termination resistors (if required) for bus line signal stability
- Maintenance Checks: Regularly inspect connectors for damage or loose connections; clean contacts periodically
