Core Specifications
Pin and Installation
Fixed pin pitch: 1.27mm, mainly in double‑row design.
Pin count: 10–100P, with 2×20PIN (40P) as a typical configuration.
Pins are mostly 0.4mm square pins.
Available in Through‑Hole and SMT versions, with straight and right‑angle orientations.
For through‑hole types, height can be selected from 8.6mm to 18.8mm.
SMT types support customizable height to fit various PCB assembly clearances.
Electrical Performance
Rated current: 1A, suitable for signal and low‑to‑medium power transmission.
Maximum contact resistance: ≤ 20mΩ for low signal loss.
Insulation resistance: ≥ 800MΩ (up to 1000MΩ for high‑end versions).
Withstand voltage: mostly 400V AC, some models up to 500V AC, effectively preventing leakage.
Temperature Resistance and Soldering
Insulators: PA6T, LCP or equivalent, UL94 V‑0 flame retardant.
Withstanding temperature:
Reflow soldering: 260°C for 5–10 seconds (up to 280°C for high‑temp versions)
Wave soldering: 230°C for 5–10 seconds
Operating temperature: -40°C to +105°C, suitable for most demanding thermal environments.
Core Structure and Material Advantages
Structural Design
Many models are equipped with positioning posts and polarization keys to prevent reverse insertion and improve assembly accuracy.
The box‑shaped housing protects internal pins, reduces mechanical damage during mating or vibration, and ensures stable connection even under offset or misalignment conditions.
Material Selection
Contacts: brass or phosphor bronze with excellent elasticity and conductivity.
Surface treatment: under‑nickel plating + gold plating, enhancing conductivity, wear resistance and corrosion resistance.
Durability: up to 500 mating cycles for some versions.
Typical Applications
Thanks to high density and compact size, this connector is widely used in:
Industrial control: PLC modules, sensor‑to‑mainboard interconnection
Consumer electronics: small routers, set‑top boxes and internal circuitry
Development boards: expansion ports for Arduino and similar platforms
Medical devices: portable diagnostic and precision test equipment
Also compatible with FFC cables and related components
Suitable for both DIY prototyping and large‑scale automated production.
Packaging
Available in tape‑and‑reel, tube and box packaging, compatible with automatic placement machines.
Most products comply with RoHS standards.
