WEIPU SA Series Industrial Connectors — Reliable, High-Performance Connectivity

SA2010/P SA2010/S Cable connector IP67 1

sa series — Robust Circular Connectors for Mission-Critical Applications

Overview

The WEIPU sa series is a family of compact, high-reliability circular connectors designed to meet the stringent demands of modern industry. Drawing on WEIPU’s expertise since 1996 and participation in drafting GB/T 11918-2014, the sa series provides reliable signal and power transmission for medical, renewable energy, rail, and smart-manufacturing systems.

Key Features

sa series connectors combine rugged mechanical design with advanced sealing and contact technologies. Typical benefits include IP69K-level ingress protection (liquid and high-temperature washdown resistance), robust corrosion-resistant housings, dependable mating cycles, and options for high-current contacts. These features ensure stable connections in vibration, dust, and washdown environments.

Applications

Engineered for mission-critical environments, the sa series is ideal for medical devices (including solutions requiring sterilization resistance), electric vehicle charging interfaces, renewable-energy inverters, industrial automation, and rail transit systems. Modular options allow mixed-signal, power, and data configurations tailored to specific system requirements.

Quality & Certification

Manufactured within WEIPU’s vertically integrated facilities (80,000 m²) and supported by nearly 30 years of experience, the sa series benefits from rigorous quality controls and global certifications such as IRIS (Rail Transit) and IATF 16949 (Automotive). WEIPU’s scale—over 70,000 specifications and production capacity up to 55 million units annually—ensures consistent supply for large projects.

Customization & Support

WEIPU offers full OEM/ODM services for the sa series with rapid prototyping (7–15 days), 24-hour technical response, and flexible tooling. Independent R&D enables tailored contact layouts, overmolding, and panel-mount or cable-assembly options to meet product lifecycle and regulatory needs.

FAQ:

Why is the SF Series suitable for precision electronic equipment?

On one hand, the gold-plated brass contacts of the SF Series ensure low-loss and stable signal transmission, avoiding signal distortion that affects equipment accuracy. On the other hand, the insulation resistance up to 2000MΩ provides excellent electrical isolation, preventing interference between different circuits and ensuring the stable operation of precision equipment.

Do you accept returns for customized products?

Due to the uniqueness of customized products, returns are not accepted, but we will rework or replace products that fail to meet the agreed standards.

What is the protection level of the Weipu SY series connectors, and what working environments are they suitable for?

The SY series connectors have an IP68 protection level. The first digit "6" means complete protection against dust intrusion, and the second digit "8" means long-term immersion in water at a specified pressure without water ingress. They are suitable for harsh environments such as outdoor rainy days, underwater short-term work, dusty industrial workshops, and oily and high-vibration construction sites.

How to choose between PPE and Zinc alloy shell?

It is recommended to choose according to the use environment: PPE shell is lightweight, corrosion-resistant and cost-effective, suitable for general industrial environments and home use scenarios; Zinc alloy shell has higher mechanical strength and impact resistance, suitable for harsh environments with frequent collision and vibration, such as construction machinery and outdoor heavy-duty equipment.
