Electrical power supply connector

wire-to-wirecircularlocking

Product overview
Pre-molded M25 2-pin 50A push-locking waterproof connector with IP67-rated sealing and pre-assembled cable, designed for reliable outdoor power connections in solar photovoltaic (PV) and energy storage systems. Suitable for industrial and lighting power distribution requiring sealed connections. The connector features UL94 V-0 housing and a wide operating temperature range for long-term field use.

Key features

• 50A rated power delivery — Φ3.5mm copper alloy contacts supporting 50A at 500V, for high-current DC/AC applications.
• Push-locking mechanism — Tool-free quick connect/disconnect with self-locking design to maintain secure contact under vibration.
• IP67 waterproof and dustproof — Fully sealed to resist water, dust and oil ingress for outdoor and industrial environments.
• Wide cable compatibility — Supports 1.0mm²–6mm² (18–9 AWG) cores with maximum outer diameter MAX φ16mm; supplied pre-molded on cable.
• Durable construction — UL94 V-0 flame-retardant housing and operating temperature range -40℃ to 105℃.
• Certifications — ISO9001, CE, UL, RoHS.
