The Industrial Waterproof RJ45 Panel Connector series is designed to mount an RJ45 Ethernet interface securely onto an equipment panel, enclosure, cabinet, or chassis.

Unlike a conventional loose Ethernet cable connection, the panel-mount design creates a fixed external RJ45 access point while allowing the rear side to connect to another RJ45 interface, PCB, or internal wiring harness.

The family includes five primary mechanical configurations:

RJ45 waterproof panel female connector with tethered screw cap
Round RJ45 panel female connector with shielded right-angle PCB structure and no protective cap
RJ45 waterproof panel female connector with hinged protective cover
M20.8 RJ45 waterproof panel female connector with tethered screw cap
M21 RJ45 waterproof panel female connector with tethered screw cap

Three rear termination configurations are available:

Feedthrough
Solder Pin
Solder Wire

This allows equipment manufacturers to select the appropriate configuration according to panel cutout, PCB layout, internal wiring, environmental protection, and maintenance requirements.

Type 1:

RJ45 Waterproof Panel Female Connector with Tethered Screw Cap

Product 1 features a round panel-mount structure with a front RJ45 female interface and a tethered screw-on protective cap.

When the Ethernet port is not in use, the protective cap can be secured over the interface. The tether keeps the cap attached to the connector and helps prevent it from being misplaced during maintenance.

Available configurations include:

Feedthrough / Solder Pin / Solder Wire

Type 2

Shielded Right-Angle PCB RJ45 Panel Connector

Product 2 uses a single-hole rear-nut panel mounting structure with an RJ45 female interface on the front and a PCB-oriented termination structure on the rear.

Its key configuration is:

Capless front interface + shielded structure + right-angle PCB connection.

Compared with cable-tail or rear-RJ45 configurations, this version is suitable for equipment where the Ethernet interface is integrated directly with an internal PCB.

Type 3:

M22 RJ45 Waterproof Panel Connector with Hinged Cover

Product 3 uses an M22-class panel mounting structure with a hinged protective cover and is available in four housing colors:

Black / White / Blue / Yellow

Unlike a removable screw cap, the hinged cover remains mechanically attached to the connector body when opened, making it convenient for equipment requiring frequent Ethernet cable connection and disconnection.

Available versions:

Feedthrough / Solder Pin / Solder Wire

Type 4:

M20.8 RJ45 Waterproof Panel Connector with Tethered Cap

Product 4 uses an approximately M20.8 panel mounting specification, with a front RJ45 interface and tethered screw cap.

It is suitable for equipment requiring compact single-hole installation and a protective cap for the Ethernet port when it is not connected.

Compared with M21 and M22 configurations, selection should not be based only on appearance. The actual panel cutout, thread structure, panel thickness, and internal installation space should be verified against the equipment drawing before volume production.

Type 5:

M21 RJ45 Waterproof Panel Connector with Tethered Screw Cap

Product 5 uses an M21 panel mounting structure with a front RJ45 female interface and tethered screw-on protective cap.

Its functional concept is similar to the other screw-cap models, while the M21 mounting specification provides another mechanical option for equipment designers.

It can be used in new equipment designs or retrofit projects where an existing panel opening needs to be matched.

Available configurations:

Feedthrough / Solder Pin / Solder Wire

Product Features

Multiple Panel Mounting Options

The series includes standard round panel structures as well as M20.8, M21, and M22 mounting options for different enclosure designs.

Three Rear Termination Structures

Feedthrough, solder-pin, and solder-wire versions support standard Ethernet cable, PCB, and internal harness integration.

Multiple Port Protection Designs

Tethered screw caps, hinged covers, and capless configurations allow the protection method to match different equipment and access requirements.

Designed for Industrial Equipment Integration

The fixed panel design integrates the RJ45 port into the equipment enclosure, providing a structured interface for installation and maintenance.

Product Breakdown

Why Is This Product Needed ?

A standard RJ45 connector solves the basic Ethernet connection requirement, but industrial equipment normally requires more than simply providing an Ethernet port.

Control cabinets, industrial computers, test instruments, communication equipment, and automation systems may also need to address:

How the RJ45 port is secured to the enclosure
How external Ethernet cables can be connected and disconnected
How the port is protected when not in use
Whether the rear side connects to another RJ45 connector or a PCB
Whether internal wires need to be soldered directly
How external cable stress can be isolated from the internal electronics
How different panel cutout requirements can be accommodated

The Industrial Waterproof RJ45 Panel Connector series is designed around these installation, protection, and internal connection requirements.

It converts a conventional RJ45 interface into a fixed panel-mounted network access point suitable for industrial equipment integration.

Typical Applications

Industrial Automation and Control Cabinets

Suitable for PLC cabinets, automation control boxes, robot controllers, and industrial Ethernet nodes.

Industrial PCs and Embedded Systems

Can be used as an external RJ45 Ethernet interface for industrial computers, edge devices, and embedded control systems.

Test, Measurement, and R&D Equipment

Suitable for test instruments, R&D platforms, laboratory equipment, and Ethernet test systems.

Core Performance Advantages

Mechanical Stress Management

The panel mounting structure helps transfer external insertion and cable loads to the enclosure rather than placing all mechanical stress directly on the internal PCB or wiring.

Flexible Internal Network Architecture

Feedthrough, PCB, and solder-wire configurations support modular cabling, board-level integration, and custom harness architectures.

Suitable for OEM Standardization

OEM manufacturers can standardize the external RJ45 interface across equipment platforms while selecting different internal termination methods.

Frequently Asked Questions

Product FAQ

Are All Five Products RJ45 Female Connectors ?

Yes. According to the supplied product information, all five configurations use an RJ45 female interface on the equipment-facing side.

The rear termination can vary between RJ45 feedthrough, solder-pin PCB, and solder-wire configurations.

What Is the Difference Between Feedthrough, Solder-Pin, and Solder-Wire Versions ?

Feedthrough versions connect to another standard RJ45 cable internally, solder-pin versions integrate directly with a PCB, and solder-wire versions connect to an internal custom harness.

The main difference is the internal termination method rather than the basic function of the front RJ45 interface.

What Is the Difference Between M20.8, M21, and M22 ?

The primary difference is the mechanical mounting specification.

Connectors should not be considered interchangeable based only on appearance. Panel cutout, thread, pitch, panel thickness, and internal clearance should be checked against the corresponding drawing.

Which Version Is Better for Frequent Access ?

For frequent access, a hinged cover provides convenient opening and closing because the cover remains attached to the connector body.

A tethered screw cap is suitable when a screw-secured protective closure is preferred while preventing the cap from being misplaced.

Are Wholesale and OEM Customization Available ?

The series is suitable for wholesale RJ45 connectors, custom industrial RJ45 connectors, OEM equipment projects, and custom RJ45 cable assemblies.

Mechanical drawings, connector configuration, pinout, Ethernet performance, and environmental requirements should be confirmed before volume production.
