Compatibility Statement
Basic Product Knowledge
What Is an RJ45 Ethernet Panel Mount Cable ?
An RJ45 panel mount Ethernet cable is a pre-terminated cable assembly that combines Ethernet data transmission with a fixed panel-mounted interface.
One end typically connects to an internal PLC, industrial PC, switch or controller, while the other end is mechanically installed on an equipment enclosure, cabinet or panel.
This allows an internal Ethernet port to be extended to an externally accessible RJ45 interface.
What Is RJ45 8P8C ?
The connector commonly referred to as RJ45 in Ethernet applications normally uses an 8P8C configuration.
8P8C means:
8 Positions / 8 Contacts
The connector contains eight contact positions and eight electrical contacts.
In a four-pair Ethernet cable, eight conductors form four twisted differential pairs for network communication.
For this reason, selecting an RJ45 Ethernet cable requires more than checking connector appearance. Pin assignment, cable category, shielding method and equipment interface definition should also be verified.
What Is CAT5E ?
CAT5E is a widely used twisted-pair Ethernet cable category that typically supports frequencies up to 100 MHz and is commonly used with 10BASE-T, 100BASE-TX and 1000BASE-T networks.
For PLC control systems, CNC machines, industrial PCs, automated test equipment and general industrial Ethernet networks, CAT5E remains a mature and cost-effective cabling solution.
Why Is Shielding More Important in Industrial Ethernet ?
Pain Points and Product Value
Challenge 1:
Internal RJ45 Ports Are Difficult to Access
Many PLCs, industrial PCs and embedded network modules are installed inside equipment enclosures.
Without a panel-mounted Ethernet interface, technicians may need to repeatedly open the cabinet when downloading programs, configuring networks or servicing equipment.
PCM-0164 extends the internal Ethernet interface to the outside of the equipment, making network access and maintenance more convenient.
Challenge 2:
Standard RJ45 Extension Cables Cannot Be Securely Panel Mounted
A standard RJ45 male-to-female extension cable can extend an Ethernet connection, but its female connector is generally not designed for secure installation on an equipment enclosure.
Inside OEM equipment, this can result in unsupported connectors, cable movement and inconsistent assembly.
PCM-0164 uses a circular panel mount structure, allowing the RJ45 female connector to become a fixed external interface on the equipment.
Challenge 3:
Limited Internal Equipment Space
Industrial equipment often contains power supplies, control boards, PLCs, relays and multiple cable harnesses in a limited space.
Overly long Ethernet patch cables can create unnecessary cable accumulation.
The standard 300±15 mm length of PCM-0164 is well suited for short internal connections between an Ethernet port and a nearby equipment panel.

Shielded RJ45 8P8C Male → CAT5E STP 24AWG × 4P Cable → RJ45 8P8C Circular Female Panel Mount
This configuration can extend an internal PLC, industrial PC, Ethernet controller or network module interface to the exterior of an equipment enclosure.
Its standard 300±15 mm length helps reduce excessive internal cabling while maintaining sufficient routing and bending allowance
Applications:
Suitable for PLC control cabinets, automated production lines, CNC machines, industrial PCs, automated test equipment, EV charging stations, photovoltaic control systems, smart manufacturing equipment and industrial network enclosures.

Standard RJ45 Cable vs. Panel Mount Cable
Therefore, standard RJ45 patch cables and panel mount Ethernet cables serve different purposes rather than representing better or worse solutions.
A standard patch cable is normally sufficient for connecting computers, routers and switches.
When an internal Ethernet interface must be securely extended to an equipment enclosure or control panel, an RJ45 panel mount cable is generally the more appropriate solution.

How to Select an RJ45 Panel Mount Ethernet Cable ?
● Confirm the Ethernet Speed
First determine whether the equipment requires 10 Mbps, 100 Mbps, 1000 Mbps or a higher Ethernet speed.
PCM-0164 is primarily intended for CAT5E-class 10/100/1000 Mbps Ethernet applications.
For 10 Gigabit Ethernet, CAT6A or a higher-performance solution should be evaluated.
● Confirm Connector Gender
The required connector gender on both the internal and external sides should be confirmed before selection.
PCM-0164 uses:
Internal Side: RJ45 Male
External Panel Side: RJ45 Female
This makes it suitable for extending an internal RJ45 interface to the exterior of an equipment enclosure.
● Confirm the Panel Cutout
One major difference between a panel mount cable and a standard Ethernet cable is the need to match the mechanical dimensions of the equipment panel.
The reference cutout for PCM-0164 is 25 mm, but the final dimension and tolerance should be verified against the approved drawing before mass production.
Panel thickness, locking method, connector protrusion and available internal space should also be considered.
● Determine Whether Shielding Is Required
If Ethernet cabling is installed near servo motors, VFDs, relays, high-power supplies or industrial drives, STP or S/FTP shielded cable should normally be evaluated.
However, shielded cable should be combined with proper grounding and shield termination to achieve effective EMI control.
● Confirm Cable Length
Longer is not necessarily better when selecting a panel mount Ethernet cable.
Cable length should be calculated based on the internal port location, routing path and panel interface position, with sufficient allowance for installation.
PCM-0164 has a standard length of 300±15 mm and can also be customized.
● Confirm Environmental Protection Requirements
Panel mounting does not automatically mean waterproof protection.
For outdoor, dusty, humid, rain-exposed or washdown environments, additional requirements such as IP rating, sealing gaskets, dust caps, jacket material and operating temperature should be confirmed.

Frequently Asked Questions
01.Why Use Shielded Cable?
Industrial equipment may be exposed to electromagnetic noise generated by motors, VFDs and industrial power supplies.
Shielded twisted-pair cable helps reduce the influence of external EMI on Ethernet signals, particularly in electrically noisy industrial environments.
02.Is a 25 mm Cutout Suitable for Every RJ45 Panel Mount Cable?
No.Different panel mount connectors may use different threads, shells, locking nuts and sealing structures.The actual mechanical drawing should always be verified before machining the equipment panel.
03.Does RJ45 Panel Mount Mean Waterproof RJ45?
No.Panel mount describes the installation method, while IP67 or IP68 describes environmental sealing performance.For outdoor or high-humidity applications, a product with the required IP rating should be specifically selected.
04.Can the Cable Length Be Customized?
Yes.Cable length can be customized according to the internal RJ45 port location, panel position, cable routing direction and required installation allowance.
