1. Core Specifications
| Parameter Category | Specification | Standard Compliance |
|---|---|---|
| Rated Current | 3A (AC/DC) | Compliant with IEC 60512-3-1 and UL 94V-2 |
| Rated Voltage | 250V AC/DC | Meets IEC 60664-1 insulation coordination requirements |
| Contact Resistance | ≤20mΩ (tin-plated); ≤10mΩ (gold-plated) | Measured per IEC 60512-3-1; ensures stable signal transmission |
| Insulation Resistance | ≥1000MΩ (500V DC, ambient); ≥100MΩ (40°C / 95% RH) | Verified under IEC 60512-3-1 environmental stress conditions |
| Dielectric Withstand Voltage | 1000–1500V AC for 1 minute | Designed per IEC 60664-1 creepage and clearance guidelines |
| Operating Temperature | -40°C to +105°C | Extended-range variants support harsh environmental operation |
| Material Composition | - Contacts: Phosphor bronze (C5191) or high-conductivity copper alloy - Insulator: PA66 (UL94V-2) or L- CP (UL94V-0) Plating: Tin (standard), Gold (high-reliability) | Material selection optimized for conductivity, corrosion resistance, and thermal stability |
| Mating Cycles | ≥500 cycles | Validated through mechanical endurance testing under repeated insertion/removal |
Note: Current rating derates to 1.2A at 85°C ambient temperature to maintain thermal safety
Reliable Mating Mechanism: Features a push-pull lock design to prevent accidental disconnection under vibration or mechanical stress.
Vibration Resistance: Engineered to meet USCAR-2 automotive vibration standards, ensuring uninterrupted signal integrity in dynamic environments.
Corrosion Resistance: Tin-plated contacts suitable for general industrial use; gold-plated variants recommended for marine, chemical, or high-humidity applications.
Signal Integrity: For applications exceeding 100MHz, gold-plated contacts with controlled impedance cabling are recommended to minimize reflection and crosstalk.
Thermal Management: Recommended wire gauge: 0.5mm² (AWG24) for 3A continuous current. Higher current demands require parallel conductors or enhanced heat dissipation design.
Automotive Electronics: ECU sensor interfaces, LED lighting control, infotainment system wiring
Industrial Control Systems: PLC modules, relay terminal blocks, HMI interfaces, servo drive communication
Telecommunications: Router backplanes, base station module interconnects, fiber transceiver power distribution
Consumer Electronics: LED strip power connections, PCB test points, wearable device internal wiring
Renewable Energy: Inverter control units, BMS signal acquisition systems
The push-pull lock variant is now an industry-standard solution in motion-critical systems such as AGVs and robotic arms, significantly reducing connection-related failures.
