25W3 In-line High Current D-type Connector Product Basis Overview
dsub 25 straight-socket connector, 22 needle signal + 3 needle high current mixed construction, standard DB enclosure size, PCB straight-socket solder plate installation, no need for bending, vertical socket fixed, and suitable for industrial control power, energy storage, servo equipment, communication cabinet, vehicle electric control and other signal + high power transmission scenarios.
Core product advantages
1. Hybrid integration: 22 conventional signals + 3 independent high current, save the development interface, save PCB layout space.
2. Direct-inserted welding plate: Standard direct-inserted needle joints, peak welding / manual welding suitable, and strongly installed, resistant to vibration and not easy to deweld.
3. High current carrying: 3 cores independently thickened terminals, overload does not heat and does not burn needles, and is suitable for high power supply.
4. Strong anti-interference: metal shielding case optional, effective shielding EMI electromagnetic interference, signal transmission stability without packet loss.
5. Long-lasting and reliable: the gilded touch points are resistant to insertion and oxidation, and are suitable for harsh industrial conditions such as dusty, wet, high and low temperatures.
25 d sub power connector In-line D-connector Customer Application Cases
1: Industrial servo drives
Customer pain point: The actuator needs to access multiple control signals and high power supply in the main circuit at the same time, the PCB space is compact, the in-line interface is necessary to facilitate batch welding, the equipment is easy to contact with poor long-term vibration.
Selection: 25W3 in-line welding plate type D connector, 3 needles carrying 30A large current power supply, 22 needles transmission pulse, communication, feedback signal.
Application effect: In-line fit PCB layout, high welding consistency; The entire machine has no heat and no signal error codes in long-term operation, and the vibration resistance meets the long-term continuous industrial conditions.
2: Energy storage unit cabinet
Customer pain point: The internal energy storage chamber needs to centralize the collection of battery cluster signal + large power input of the entire machine, requiring flame resistance, temperature resistance, and straight-plug installation wiring.
Selection: 25W3 in-line flame retardant sub d connector 25 pin, UL94-V0 rubber core, wide temperature aging resistant design.
Application effect: A single interface achieves integration of signal + power access, simplifying cabinet wiring; High temperature resistance is not softened, the temperature increase in long-term operation with full load can be controlled, and the safety and stability are met.
