【Product Description】Selection and Application of Waterproof Connectors (Including Wohu Part Numbers)

       Product Overview

　　Network ports of outdoor equipment such as security devices, outdoor APs, and charging piles must be dustproof, waterproof, resistant to temperature variations, and protected against lightning strikes. Waterproof RJ45 connectors should be selected based on protection rating (IP65/IP67), mating angle, voltage withstand capability, and mating cycle life, along with multi-stage lightning protection. Refer to Wohu’s WHPMWRJ series, e.g., WHPMWRJ1101 (IP67, 1000VAC for 1 minute, 750 mating cycles, operating temperature -40°C to +85°C). All part numbers listed are genuine Wohu models; refer to official datasheets and sample evaluations for final confirmation.

　　Selection Guidelines

　　• Determine Protection Rating: Prefer IP67 for fully outdoor applications; IP65 is sufficient for semi-outdoor use. Pay attention to voltage withstand (e.g., 1000VAC for 1 minute) and mating cycle life (e.g., 750 cycles).

　　•Determine Structure: Select mating angle (90°/180°) and panel-mount type according to installation method.

　　• Implement Lightning Protection and Wide-Temperature Support: Use a three-stage lightning/surge protection scheme at the port (GDT + TVS + ESD) and select components rated for -40°C to +85°C.

　　Frequently Asked Questions

　　Q1: What is the difference between IP65 and IP67?

　　A: IP67 offers temporary immersion protection and superior sealing—preferred for outdoor use; IP65 protects against water jets and is adequate for semi-outdoor environments.

　　Q2: Is lightning protection still needed for waterproof network ports?

　　A: Yes. Outdoor installations require GDT + TVS + ESD staged surge suppression to handle lightning-induced transients. Waterproofing prevents water ingress, while lightning protection addresses electrical surges.

　　Typical Applications

　　Suitable for data communications, industrial control, photovoltaic energy storage, security and surveillance, and other applications. Online selection tools, datasheet downloads, and sample requests are available.
