Component Specifications

Definition
Connectors are electromechanical components designed to create temporary electrical connections between interface circuit boards and other electronic systems. They facilitate reliable signal transmission, power delivery, and data communication while allowing for modular assembly, maintenance, and replacement in industrial equipment.
Working Principle
Connectors establish electrical continuity through mating contacts (pins and sockets) that maintain physical and electrical connection via spring tension, friction, or locking mechanisms. They provide pathways for current flow and signal transmission while ensuring proper alignment, insulation, and environmental protection.
Materials
Contacts: Phosphor bronze, beryllium copper, or brass with gold/nickel/tin plating. Housing: Thermoplastics (PBT, PPS, LCP), thermosets (epoxy), or metal alloys. Insulators: High-temperature plastics with UL94-V0 flame rating.
Technical Parameters
  • IP Rating IP20-IP67
  • Mating Cycles ≥500 cycles
  • Current Rating 1A-50A
  • Voltage Rating 50V-600V AC/DC
  • Contact Resistance ≤20mΩ
  • Insulation Resistance ≥1000MΩ
  • Operating Temperature -40°C to +125°C
Standards
ISO 9001, IEC 60512, MIL-DTL-38999, DIN 41612
