Product Performance

• High-Density Signal Distribution: The 2.54mm pitch design integrates 81 terminals, saving 40% of control cabinet space, suitable for automation equipment requiring a large number of signal accesses (such as CNC machine tools, process control systems).
• Tool-Free Quick Wiring: Spring pressure connection technology supports one-handed wire insertion, improving wiring efficiency by 70%, and has an anti-loosening self-locking function to ensure connection stability in vibrating environments.
• High-Reliability Contact: Gold-plated contacts (thickness ≥3μm) and anti-oxidation coating resist industrial environmental corrosion, with contact resistance increase ≤10% after salt spray test (5% NaCl solution, 96 hours).
• Wide Temperature Stability: In the full temperature range of -40°C to +85°C, terminal resistance drift ≤3%, adapting to severe cold regions and high-temperature industrial scenarios.
• Intelligent Diagnosis Function: Optional LED status indicator module for real-time monitoring of each terminal’s on/off status, with fault location accuracy reaching single-channel level.
