200mm Panel Mount RJ45 Male to Female PoE Blocking Cable

An external network connection does not always need to deliver power into the equipment. Goochain's 200mm RJ45 male-to-female panel-mount cable with internal magnetics is developed for installations that need an accessible Ethernet socket and a defined barrier to PoE DC power reaching the male-plug side.

The assembly combines an RJ45 plug, an RJ45 socket, mounting ears and a 5.5mm cable outer diameter. Its internal magnetic circuit is specified around the required Ethernet link and power-blocking arrangement. The intended connection places the female socket at the external network entry and the male plug at the equipment port.

Bring the Network Socket to the Enclosure

A network port inside a housing can be awkward to reach during installation or servicing. The mounting-ear arrangement provides a fixing point at the panel, while the short male-ended lead connects to the internal equipment port. This keeps the external plug-in point accessible without moving the main board.

The 200mm length suits a short internal route. Check it against the actual socket position, connector body length and space needed for a natural cable bend. Mounting-hole spacing, panel thickness and plug-latch access should be reviewed together before the enclosure cutout is finalized.

For other connector arrangements or routing lengths, our Ethernet Cables range provides a starting point for a custom assembly.

Define the Data Path and the Power Boundary

The design requirement is to maintain the specified Ethernet data connection while preventing PoE DC power on the female side from reaching the RJ45 male end. Internal magnetics form part of that circuit; their selection and the complete wiring arrangement determine the result.

PoE blocking must be checked across every relevant conductor path, including any connections that could bypass the magnetic coupling. The supported network speed, power-source type and blocking limits are therefore defined for the approved build and verified on the intended equipment.

Build Specification

Check the Fit Before Closing the Housing

This arrangement can be considered for POS enclosures, kiosks and embedded equipment where the internal Ethernet port should receive data without the specified external PoE supply. The equipment still needs its own intended power source.

For the mechanical review, provide the panel cutout, hole spacing and available depth behind the socket. A photo of the internal route helps establish whether the 200mm lead reaches comfortably and whether a technician can release the RJ45 latch without removing nearby parts.

From the Circuit Requirement to a Repeatable Cable Build

Goochain supports OEM and ODM cable development at its 5,000 m² manufacturing facility in Dongguan. For this assembly, the project starts with two inputs: the enclosure layout and the electrical boundary the cable must provide. Connector selection, magnetic components, wiring, strain relief and identification are then defined in the sample specification.

Sample approval should include data-link operation at the agreed speed and verification of the specified DC blocking under the agreed supply conditions. The accepted circuit, component list and mechanical drawing become the production reference. Our Factory & Quality page outlines the inspection stages used in manufacturing.

Before You Specify This Assembly

Will the male end supply power to my equipment?

The specified design is intended to block PoE DC delivery to that end. Equipment connected there must use its intended separate power source.

Can I specify Gigabit Ethernet or a particular PoE source?

Include the required link speed and switch or injector details in the inquiry. Neither the RJ45 connector format nor the 5.5mm cable diameter establishes the supported speed or PoE blocking coverage. Those requirements need to be checked against the complete circuit and sample results.

Can the mounting arrangement or length be changed?

Yes, custom configurations can be reviewed against your panel drawing and internal route. Specify the length measurement points, fixing dimensions and required cable-exit direction so the sample can be checked in the actual housing.
