II. Core Product Features
Full Range of Pitches for Various Circuit Densities
Covering three industry-standard pitches: 1.27mm, 2.0mm and 2.54mm to meet different layout requirements:
1.27mm: ultra-dense layout for space-limited equipment such as micro industrial control boards and sensor modules;
2.0mm: balanced density and stability, commonly used in communication equipment and automotive electronic control units;
2.54mm: universal standard for development boards, instruments and meters, compatible with mainstream pin headers and wiring harnesses.
All pitches support single-row / dual-row structures with pin counts from 2–64Pin, customizable to meet various signal and power transmission demands.
Three Mounting Types for Flexible PCB Design
Through-Hole (DIP):
Pins are inserted vertically into PCB through-holes for high bonding strength, excellent vibration resistance and stable insertion force. Ideal for industrial control boards, servo drives and other high-vibration environments. Thickened pins effectively prevent cold joints and solder detachment.
Surface-Mount (SMT):
Compatible with automatic placement machines with mounting accuracy ≤±0.08mm, supports reflow soldering. Low-profile design down to 2.2mm saves vertical PCB space, suitable for slim smart devices and portable medical instruments.
Right-Angle:
90° bent pins for horizontal signal transfer, avoiding vertical wiring conflicts. Available in 90° horizontal and 180° straight types, widely used in communication backplanes and industrial all-in-one interface modules.
High-Stability Connection for Reliable Signal Transmission
Terminals are made of high-purity oxygen-free copper with gold plating ≥0.3μm, contact resistance ≤20mΩ, providing excellent oxidation and wear resistance for low signal loss. Dual-row connectors feature staggered terminals to reduce crosstalk, with impedance controlled at 50Ω±5Ω for high-frequency applications.
Dual-contact internal clips ensure insertion force of 0.8–1.2N per pin, smooth operation without jamming. Insertion life exceeds 5000 cycles, far exceeding industry averages.
Excellent Insulation & Wide Operating Temperature
Housing uses UL94 V-0 flame-retardant engineering plastic, insulation resistance ≥1000MΩ, withstand voltage ≥AC500V, effectively preventing short circuits and ensuring safety. Black casing provides light shielding and easy identification.
Stable operating temperature range: -40℃ ~ 105℃, resistant to cracking in low temperatures and contact failure in high temperatures, suitable for industrial, automotive and outdoor environments.

V. FAQ
Q1: Is the insertion force the same for all three pitches?
A1: No. Insertion force increases with pitch:
1.27mm: approx. 0.8N per pin
2.0mm: approx. 1.0N per pin
2.54mm: approx. 1.2N per pin
All meet industry standards and can be selected based on frequency and stability requirements.
Q2: What are the reflow soldering parameters for SMT types?
A2: Peak temperature: 260℃±5℃
Time above 245℃: ≤10 seconds
Total cycle: 3–5 minutes
Gradual cooling recommended to avoid housing deformation.
Q3: Do you support shielded female headers?
A3: Yes. We can add metal shielding with shielding effectiveness ≥80dB@1GHz to resist electromagnetic interference for high-speed communication and medical equipment. Please provide required shielding level and dimensions.
