Specifications


Challenges

In IoT, solar tracker, energy storage, and robotics applications, conventional USB connectors often face persistent challenges, including water ingress and short circuits, unreliable electrical contact, and wear-related failures after repeated mating cycles. Exposure to dust, rain, and temperature fluctuations can cause oxidation and pin corrosion in standard USB interfaces, leading to equipment downtime and increased after-sales maintenance costs. For products deployed outdoors or in mobile applications, inadequate connector protection can become a critical weak point in overall system reliability.

This USB connector features a sealed mated design that provides protection against water and dust ingress at the interface level. It helps maintain reliable USB signal and power transmission under harsh environmental conditions, reducing equipment failures caused by connector issues and lowering maintenance and operational costs.

Positioning

The USB waterproof connector is designed for industrial and outdoor applications, serving customers across the IoT, solar tracker, energy storage, and robotics manufacturing industries. It addresses key challenges associated with USB interfaces in humid, dusty, and water-spray environments, including water ingress, oxidation, and unreliable electrical contact.

Features

1. IP67-Rated Mated Sealing for Protection Against Water and Dust Ingress

The connector features a sealed mated design and achieves an IP67 protection rating, helping keep internal contacts isolated from water and dust during temporary immersion and exposure to dusty environments. Compared with conventional exposed USB interfaces, it offers enhanced protection in applications such as outdoor rain exposure, equipment washdown, and dusty industrial facilities, reducing the risk of short circuits and unreliable electrical contact caused by water or dust ingress. This helps minimize equipment downtime and after-sales service requirements resulting from connector corrosion.

2. Wide Operating Temperature Range for Environments from -40°C to +85°C

With an operating temperature range of -40°C to +85°C, the connector is designed for reliable use in environments with significant temperature variations, including low-temperature outdoor installations, high-temperature vehicle compartments, and industrial workshops. Compared with standard USB connectors designed for conventional ambient conditions, it is engineered to reduce the risk of housing embrittlement, seal failure, and contact resistance drift under extreme temperature cycling. This helps customers minimize product requalification and connector replacement caused by insufficient temperature adaptability when deploying equipment across different climate zones.

3. 1,500 Mating Cycles for Applications with Moderate Connection Frequency

With a mechanical durability rating of 1,500 mating cycles, the connector is suitable for applications involving periodic maintenance, module replacement, and moderate-frequency mating and unmating. Compared with single-use sealed connectors or basic waterproof solutions with limited mating durability, it combines environmental protection with predictable mating-cycle performance. This helps reduce connector replacement frequency throughout the equipment lifecycle and lower long-term operation and maintenance costs.
