Waterproof Micro USB Receptacles for Reliable Connectivity in Harsh Environments

As electronic devices are increasingly deployed in outdoor, industrial, and moisture-exposed environments, standard USB connectors often become a weak point in system reliability.
To address this challenge, Walta Electronic offers Waterproof Micro USB Receptacles designed to protect signal integrity and power delivery even under demanding conditions.

Designed for Moisture-Resistant Applications

The U03-C113-00501 and U03-C113-00502 Micro USB receptacles are engineered with a dedicated waterproof sealing structure, helping prevent water ingress at the connector interface.
This makes them suitable for applications where condensation, splashes, or high humidity are unavoidable.

Key design considerations include:

  • Precision-fitted seal ring structure to reduce moisture penetration

  • Stable mechanical design for long-term PCB mounting

  • Reliable electrical performance compliant with USB 2.0 specifications

Durable Construction for Long-Term Use

Both models feature a stainless steel shell combined with gold-plated contacts, providing improved corrosion resistance and stable contact performance over time.

  • Insertion durability: Rated for 10,000+ mating cycles

  • Material selection: Designed to withstand repeated use in harsh environments

  • Electrical stability: Supports consistent data and power transmission

This construction helps reduce field failures and maintenance costs in real-world deployments.

Typical Applications

Waterproof Micro USB receptacles are commonly used in:

  • Industrial controllers and automation equipment

  • Outdoor sensing and monitoring devices

  • Portable or ruggedized electronic products

  • Embedded systems exposed to moisture or dust

For designs that still rely on Micro USB interfaces, adding waterproof protection at the connector level can significantly improve overall system reliability.

Product Overview

Both models are suitable for PCB mounting and can be evaluated based on specific mechanical or layout requirements.
