New M25 2+1+5 core, nylon material, high voltage, new energy, waterproof, IP67, self-locking connector.
M25 size, 2+1+5 pin configuration (2 for main power line, 1 for signal/ground or neutral, 5 for control/auxiliary signal port), made of engineering nylon (PA) material, with a self-locking structure and anti-detachment design, it is a high-voltage waterproof connection solution designed specifically for new energy power systems (such as photovoltaic inverters, energy storage equipment, electric charging piles, small motor control boxes, etc.). The whole unit meets the IP67 protection rating, is weather-resistant and corrosion-resistant, easy to install, and has low maintenance costs.
Product Highlights (Selling Points)
High Protection Rating: IP67 (short-term immersion), suitable for outdoor and humid environments.
Self-Locking Structure: Reliably locks in place without additional tools, preventing loosening and mis-insertion.
High Voltage Resistant Design: Compatible with common voltage levels in new energy systems (see electrical performance table).
Excellent Insulation and Heat Resistance: Flame-retardant nylon material, wide temperature range, and anti-aging properties.
Modular Pin Layout: 2+1+5 pin layout, supporting integrated power + signal/control cabling.
Installation-Friendly: Suitable for both panel mounting and cable connection, high insertion/removal cycles, and long lifespan.

Performance Test Report (Factory Test)
| Parameter | Common typical values or ranges | Notes |
| Voltage Rating | 250 V / 400 V / 450 V | Some models support high voltage levels (such as solar or power systems) |
| Current Rating | Main power pin test (2 pins) | 30A ~ 35A |
| Contact Resistance | ≤5 mΩ | Some outdoor connector designs require ≤ 5 mΩ to reduce heat and voltage drop |
| Signal pin test | Low power pin test (5 pins) | 3A ~ 5A |
| Dielectric Withstanding Voltage | Several thousand volts (e.g. 1.5 kV / 60 s, etc.) | Responding to surges or transient overvoltages |
| Insulation Resistance | ≥10 MΩ / 500 VDC | Prevent leakage and insulation breakdown |
| Operating Temperature | –40°C to +105°C (or higher) | For outdoor environments with temperature changes |
| Ingress Protection | IP68 | Indicates that it can be immersed in water for a long time under specified conditions and prevent dust from entering |
| Media durability / humidity / salt spray test | Often pass salt spray test / high humidity aging test | For long-term outdoor reliability |
