Product Overview
The 1.25mm pitch horizontal SMT connector, developed by Shenzhen Huaxinrong Electronic Technology Co., Ltd. (founded in 2018, registered capital of 1 million RMB, 1,800㎡ factory), is one of the core high-precision connection products in the electronic component industry.Adopting a horizontal SMT process and an ultra-small 1.25mm pitch design, this connector is widely used for signal and power transmission in tact switches, connectors and other electronic products.Supported by our mature full‑cycle manufacturing system (design – R&D – production – assembly – testing), we have served more than 200 customers. It is the preferred connecting component for highly integrated electronic equipment.
Product Features
Ultra-small pitch design:1.25mm terminal pitch, suitable for high‑density PCB layouts, enabling multi‑channel signal transmission in limited space to meet the miniaturization requirements of consumer electronics and industrial control equipment.
Horizontal SMT mounting process:Adopts surface mount technology with stable soldering performance. It is mounted flat against the PCB to reduce vertical space occupation, compatible with automated SMT production lines and improving production efficiency.
High‑reliability terminal structure:Terminals are made of high‑elasticity copper alloy, with contact resistance ≤20mΩ and insertion/extraction life ≥5000 cycles. It features excellent anti‑vibration and anti‑shock performance, suitable for complex working environments.
Eco‑friendly materials and technology:Compliant with RoHS environmental standards. The housing is made of high‑temperature resistant LCP plastic (heat resistance ≥260℃), capable of withstanding reflow soldering without deformation or material shedding.
Wide compatibility with multiple specifications:Supports pin count customization from 2P to 16P to meet different circuit signal and power transmission requirements. Gold plating thickness on terminals is ≥0.8μm, providing excellent oxidation and corrosion resistance.

FAQ
Q1: What is the rated current of the 1.25mm pitch horizontal SMT connector?
A: The standard 2P version is 1A per pin. For 4P and above, it is 0.5A per pin. High-current versions up to 2A per pin are available upon request.
Q2: Does the connector support manual soldering?
A: Yes, but SMT automation is recommended. For manual soldering, use a soldering iron below 350℃ and keep soldering time within 3 seconds to avoid damaging terminals.
Q3: What are the storage conditions?
A: Store in a dry environment at −10℃ ~ 40℃, humidity < 60%. Unopened package shelf life is 12 months.
Q4: Can you provide reliability test reports?
A: Yes. We offer third-party test reports including salt spray, vibration, and insertion/extraction life tests. Contact customer service before ordering.
Q5: Are there discounts for bulk orders?
A: 10% off for orders ≥10,000 PCS; 15% off for orders ≥50,000 PCS. Details can be discussed with our sales team.
