Product Overview
Pre-molded M25 2-pin waterproof push-lock connector supplied with cable, designed for reliable outdoor power connections in solar PV, energy storage and industrial installations. IP67 protection and robust sealing make it suitable for harsh environments.

Key Features

• 50A high-current capacity – Φ3.5mm copper-alloy contacts support rated currents up to 50A (varies by pin count) and voltage rating up to 500V for 2/3/4‑pin variants.
• Push-lock mechanism – Tool-free quick connect/disconnect with self-locking design for secure mating in high-vibration applications.
• IP67 waterproof & dustproof – Fully sealed housing resists water, dust and oil, suitable for outdoor and factory-floor use.
• Wide cable compatibility – Accepts 1.0mm²–6mm² (18–9 AWG) conductors with maximum outer diameter MAX Φ16mm.
• Flame-retardant housing & wide temperature range – UL94 V-0 rated housing and operating range from -40°C to 105°C for long-term reliability.
• Global certifications – ISO9001, CE, UL, RoHS and TUV (model-dependent) for international installations.
