II. Product Features
Precise Pitch Design
Adopts a standard 1.25mm pitch, suitable for small-size PCB layouts. It realizes more signal transmission channels in limited space, meeting the miniaturization and high-density design trend of modern electronic products.
Dual Pin Styles for Wide Application
Straight pin type: Soldered vertically to the PCB, ideal for vertical board-to-board or board-to-wire connections.
Right angle pin type: Designed for horizontal soldering, effectively reducing overall installation height, suitable for compact equipment with strict height limits.
High-Temperature Insulation Materials
The housing uses UL-certified high-temperature resistant nylon, capable of withstanding 260℃ wave soldering / reflow soldering without deformation or glue flowing, with stable insulation performance.
Pins are made of gold-plated brass, with contact resistance below 20mΩ and strong oxidation resistance.
Foolproof and Self-Locking Structure
Built-in foolproof design avoids circuit damage caused by reverse mating between male and female connectors.
Some models are equipped with self-locking latches that provide a clear locking click, preventing disconnection due to vibration or external force.
III. Product Advantages
Full-Process Quality Control
From raw material incoming to finished product delivery, the products go through 12 inspection procedures, including insertion/extraction force test, contact resistance test, temperature resistance test, etc. Defect rate is controlled within 0.3%, far below the industry average.
Fast Customization Response
Supports customization of pin count (2P~20P), header height, solder pin length and other parameters. Prototype service is available within 72 hours to meet customers’ small-batch, multi-specification demands.
Cost-Effective Delivery
Through mass production and automated equipment, we optimize costs while ensuring quality. Prices are 20%–30% lower than similar imported products. Adequate domestic stock ensures same-day shipment for standard models.
Compliance & Environmental Certifications
Products comply with RoHS, REACH and other environmental standards, lead-free and halogen-free, meeting global environmental access requirements for electronic end products.
IV. Product Applications
This pin header series is widely used in consumer electronics, smart home, industrial control and medical equipment:
Consumer Electronics: Power and signal transmission for Bluetooth earphone charging cases, smartwatch mainboards, portable power banks.
Smart Home: Sensor connections for smart locks, LED light strip controllers, internal wiring for security cameras.
Industrial Control: PLC module interfaces, servo motor encoders, signal acquisition terminals for industrial sensors.
Medical Equipment: Test strip sockets for blood glucose meters, portable ECG monitors, power connections for household nebulizers.
V. FAQ
Q: What is the insertion/extraction life of the 1.25mm pitch pin headers?
A: Under standard test conditions, the insertion/extraction life can reach more than 5000 cycles with stable force, no obvious poor contact.
Q: What are the requirements for soldering temperature and time for right-angle pin headers?
A: For wave soldering: 240–260℃, 3–5 seconds.
For reflow soldering: peak temperature ≤ 260℃, duration ≤ 10 seconds to avoid housing deformation.
Q: Is lead-free soldering supported?
A: Yes. Both housing and pins use lead-free eco-friendly materials, fully compatible with lead-free soldering and RoHS compliant.
Q: How to choose between straight and right-angle types?
A: Choose straight pins for sufficient vertical space and vertical board-to-board connection.
Choose right-angle pins for height-limited equipment or wiring close to the PCB.
Q: Can samples be provided for testing?
A: Yes. We offer free samples for new customers. Standard samples are shipped within 24 hours; customized samples depend on specific requirements.
