Product Features
Precise Pitch Design
The 2.54mm standard pitch complies with common industry specifications, directly compatible with most PCB boards and wiring harnesses of the same specification on the market without additional mold development or adjustment, effectively reducing engineering adaptation costs.
Dual Structure Options
Vertical Connector: Soldered vertically to the PCB, saving horizontal board space, ideal for equipment with sufficient vertical space and compact layout requirements.
Horizontal Connector: Mounted parallel to the PCB surface, lowering the overall height, suitable for ultra-thin products with strict height restrictions.
Reliable Electrical Performance
Adopts high-conductivity copper alloy terminals with gold-plated surface, providing contact resistance below 20mΩ for stable signal transmission. The elastic terminal design ensures uniform insertion/extraction force and maintains reliable connection during long-term use, preventing poor contact.
Eco-Friendly Material
The housing and insulating parts are made of high-temperature-resistant nylon PA66 material, compliant with RoHS environmental standards. It withstands 260℃ wave soldering and reflow soldering processes without releasing harmful substances, meeting global market environmental access requirements.
Product Advantages
High Compatibility
As a universal industry standard, the 2.54mm pitch is widely compatible with various mainstream equipment. It enables quick replacement and upgrade for industrial control boards, consumer electronics, smart home devices, and more.
Stability & Durability
Having passed strict insertion/extraction life testing (≥5000 cycles) and vibration & shock testing, it maintains stable connection under complex working conditions, suitable for high-reliability scenarios such as industrial automation and outdoor equipment.
Cost-Effective
Standardized production processes and a mature supply chain allow us to offer competitive pricing while ensuring quality. Our full-process independent production enables fast response to small-batch customization and short delivery cycles.

FAQ
Q1: What is the current rating of 2.54mm pitch connectors?
A: Under normal temperature, the continuous current per terminal can reach 3A. The actual value varies with operating temperature and wire specification. A 20% safety margin is recommended for high-load applications.
Q2: Is there any difference in soldering methods between vertical and horizontal connectors?
A: Both structures support wave soldering and manual soldering. For horizontal connectors, ensure board flatness during soldering to avoid cold joints. For vertical connectors, control solder volume to prevent solder bead short circuits.
Q3: Is customization available?
A: We can adjust terminal length, housing color, and positioning post structure according to customer requirements. The minimum order quantity is 5000PCS, with a typical customization lead time of 7–10 working days.
Q4: How to distinguish male and female connectors?
A: Pin-type is the male connector, and socket-type is the female connector. Product model suffixes are marked with “M” (male) and “F” (female). Please refer to the selection guide when purchasing.
