Multi domain devices continue to iterate towards miniaturization and integration. The Micro-D Connector (J30J), with its differentiated structural design and performance advantages, has become a core connector that balances compact layout and harsh working conditions, providing solid support for stable operation of equipment in multiple key industries.
1. Product Features
(1) Release PCB layout space
The contact spacing of the Micro-D Connector is 1mm or 1.27mm, which improves the compactness of the connector shape, greatly saves the layout space of the PCB board, adapts to various compact precision equipment, and helps the whole machine upgrade towards smaller volume and higher integration.
(2) Full range of digit coverage requirements
The connector offers a full range of 2-144 bits to choose from, from simple signal transmission scenarios with few bits to complex high-density wiring requirements with multiple channels, flexibly matching wiring plans for different scenarios.
(3) Ensure stable electrical contact
The conventional model of connector terminals adopts a twisted wire elastic pin structure design. When the pin is inserted into a rigid socket, it will naturally produce uniform elastic deformation, forming multiple independent contact points in the contact area, avoiding the signal interruption problem that is prone to occur in single point contact. Even under slight displacement conditions, it can always maintain continuous and stable electrical connection, greatly reducing the probability of contact failure; The customized high current version adopts a Leaf spring socket or crown spring socket. Multiple sets of high elasticity copper alloys form multi-point surface contacts when inserting the pins, with a larger contact area and stronger current carrying capacity. It can stably carry a large current of 20A and maintain continuous and stable current transmission even under vibration and impact conditions.
(4) Resist vibration impact and prevent loosening
The connector is equipped with standard screw locking structures on both sides, which can form a rigid mechanical lock after the male and female seats are inserted, effectively avoiding the problems of loose connections and signal interruptions caused by high-frequency vibration, strong impact or accidental pulling during equipment operation. From the connection level, the risk of complete machine failure is greatly reduced, allowing the equipment to maintain stable operation under dynamic conditions.
(5) Balancing signal and high-power transmission
The rated current of conventional models covers 1A-5A, and the rated voltage is 100V-500V, which can meet the vast majority of conventional signal transmission scenarios; Customized high current models can achieve up to 20A high current transmission, with a rated voltage of 500V and a maximum withstand voltage of 800V AC, balancing high-density signal and high-power power supply requirements.
(6) Maintain low signal loss
The contact provides a variety of thick gold electroplating processes for 0.2/0.25/0.5 μ m, with a contact resistance of ≤ 12m Ω and an insulation resistance of up to 5000M Ω. Even after long-term use, the coating can still resist oxidation and corrosion, maintaining stable low signal loss performance and avoiding attenuation and distortion problems during signal transmission.
(7) Suitable for long-term operation under harsh working conditions
The standard plugging and unplugging life of the micro D-shaped connector can reach 500 times. The entire series of products can work stably in harsh environments with a wide temperature range of -55 º C~+125 º C, high dust, and strong vibration, greatly reducing equipment maintenance costs and extending the service life of the whole machine.
