Metal-hood PROFINET RJ45 field plug for industrial Ethernet cables
This kit is a field-assembly industrial RJ45 plug, not a clear office crystal head and not a toolless Cat6A zinc keystone. The assembled end on the green cable is an 8P8C male nose in a two-piece metal hood. The loose parts are the gold-plated contact insert, the turquoise wire manager used on PROFINET jackets, the two nickel-plated housing halves, and the fastening screws. Panel builders and machine OEMs use it to terminate industrial Ethernet and PROFINET patch leads at the cabinet, on a drive, or at a remote I/O without a factory crimp press.
Buyers searching for a PROFINET RJ45 field plug, an industrial Ethernet metal connector, or a shielded 8P8C assembly kit will specify this part when the cable is PUR or PVC, the jacket is the familiar green, and the link must pass a noisy cabinet. It is not a Cat6A office field plug and not a Cat7 load-bar crimp plug. Those are IT channel parts. This hood is built for industrial Ethernet connectors and PROFINET device ports.
Why the hood is metal and the manager is turquoise
PROFINET and most industrial Ethernet copper links run four balanced pairs in a shielded jacket. The metal halves close around the braid so the shield is 360° at the plug, not a drain wire stuffed under one screw. That bond is what keeps inverter noise off the controller. The turquoise (green-blue) insert is the PROFINET color code for the wire manager: it holds the pairs in the T568B / PROFINET map so the gold IDC blades pierce insulation in one press. Gold contacts keep resistance low after oil, condensation, and hundreds of mating cycles on a service laptop or a spare I/O module.
PROFINET is an Industrial Ethernet protocol. The connector on the cable is still the 8P8C modular connector (RJ45) so it mates a standard device jack. Category performance is typically Cat5e class for 100 Mbit PROFINET; do not print Cat6A or 10G on this SKU unless you order a tested high-frequency insert. A 4+2 insert (four data contacts plus two extras for hybrid or diagnostic pins) is available on the same hood when the drawing calls for it — the photo insert with the extra top pins is that style of contact block.
How the field kit goes together
Strip the jacket, fold the braid back, dress the four pairs into the turquoise manager, push the manager into the white/metal insert until the IDC seats, then close the two hood halves and drive the screws. The white latch on the assembled plug is the RJ45 lock. No 8P8C crimp die is required; a small screwdriver and a pair of side cutters are enough on the machine floor. Re-termination is possible if a pair is crossed — cut back and start clean rather than prying blades twice.
Typical wire is AWG 22–26 stranded industrial Ethernet, jacket about 5.5–7.5 mm. Confirm OD on the drawing so the strain pocket closes on the jacket, not on the braid alone. PUR jackets for drag chains and PVC for static cabinet jumpers both fit when the OD window matches.
Where this plug is used
PLC-to-switch jumpers, drive and encoder PROFINET ports, remote I/O, cabinet pass-through leads, and spare-parts bags for OEMs who do not want to stock molded cords in every length. Indoor IP20 cabinets are the default. For washdown or IP67, this RJ45 kit is the wrong face — use an M12 D- or X-coded plug from the same industrial Ethernet range.

Buying notes for OEM and panel shops
Write the PO as: industrial PROFINET RJ45 field plug, metal hood, shielded, IDC, turquoise manager, 8P8C (or 4+2). Do not write “Cat7 crystal head” or “office RJ45.” Those will not close on a 6.5 mm PUR jacket or bond the braid. For finished green cords see PROFINET patch cables.
Frequently asked questions
Is this a normal Cat6 RJ45 plug?
The nose is 8P8C and fits an RJ45 jack. The hood, IDC insert, and shield path are industrial. Do not use it to certify a Cat6A office channel unless you order a tested high-frequency variant.
What does 4+2 mean?
Some inserts carry four data contacts plus two extra pins (hybrid, power, or vendor-specific). The standard PROFINET jumper is 8P8C. Say which insert you need on the RFQ.
Do I need a special tool?
No factory crimp press. A screwdriver to close the hood and a cutter to trim pairs is enough. Optional assembly pliers speed the IDC press on a production cell.
Will it fit Siemens / Beckhoff / Phoenix jacks?
It fits any standard RJ45 industrial Ethernet jack with enough depth for this hood. Confirm the device manual. M12 device ports need an M12 plug, not this kit.
Can you private-label the bag?
Yes. Your part number, 8P8C vs 4+2 mark, and mixed cartons with industrial Ethernet connectors are standard OEM options.
