M12 connector-welding wire type unshielded circular metal connector, adopts straight head design and screw locking structure, the metal shell is brass nickel-plated, and has IP68 waterproof and dustproof capabilities. Supports 3-12 pin core welding wire connection, the unshielded shell design is suitable for a variety of scenarios, the structure is compact and durable, and it is suitable for harsh environments such as industrial automation and equipment connection.
1. Product Features
The connector is built with a metal shell for solid protection, and the nickel-plated brass material is corrosion-resistant and wear-resistant, ensuring long-term stable performance. The straight head shape is matched with a screw locking device, which is firmly connected and prevents falling off. The wire welding process supports the direct welding of the needle core tail to the cable, simplifying the installation process. The shield-free shell design reduces signal interference and is suitable for high-frequency or ordinary signal transmission. The IP68 protection can resist dust intrusion and deep immersion, meeting the needs of harsh working conditions such as humidity and dust. The number of needle cores covers 3-12 needle cores, which can flexibly match the interface requirements of different equipment.
2. Product size and number of needle cores
The outer diameter of the main body is φ14.0mm, the thread specification is M12×1.0, and the axial key dimensions include the front φ8.0mm transition zone, the middle thread section φ14.0mm and the tail φ7.9mm closing design. The overall length is about 23.0mm (the specific parameters are subject to the drawing). It supports free configuration of 3 to 12 pins, with flexible selection of the number of pins, compatible with signal transmission requirements in multiple scenarios, and the soldering wire interface is compatible with AWG specification cables to meet the diverse connection standards of industrial equipment.
