M1-J waterproof 9~17P wire end male head
M1-J IP65 aviation male plug (9–17P) with M16×1.5 nickel-plated brass thread, anti-corrosion & EMI shielding. Rear panel mount compatible with DIN rail enclosures, unified size for all pin counts, fits Φ6–Φ8 multi-core cables. Ideal for PV, energy storage and industrial sensors; 22mm standard thread, short thread customizable.
Description
Constructed with nickel-plated brass metal housing, this connector boasts outstanding anti-corrosion and anti-electromagnetic interference capacity, greatly extending service life in harsh industrial environments. A built-in rear rubber seal ensures IP65 dustproof and splashproof performance once the thread is fully locked, adapting to outdoor and workshop working conditions. It applies rear panel mounting structure: the threaded body penetrates the cabinet from inside and is fixed by an external hex nut, compatible with both DIN rail and wall-mounted equipment boxes.
The cable entry hole supports Φ6–Φ8 multi-core shielded wires, with differentiated rated current for different pin counts: 3A per pin for 9P, 2A per pin for 10P/12P, and 1.5A per pin for 14P/16P/17P. Notably, all 9–17Pin models share identical outer mounting dimensions, simplifying inventory management for bulk buyers. Standard long-thread units are in stock for fast shipment, and customized short-thread connectors, pin layouts, cable inlet sizes and packaging are acceptable. Widely matched with PV converters, energy storage controllers and industrial sensors, this aviation connector fully meets grid interconnection standards for new energy equipment and enables stable multi-signal transmission between PV modules, electricity meters and energy storage batteries. Factory direct supply with competitive prices and flexible lead times for your industrial and new energy projects.
