    outdoor trunking?

    Is it the whole run or just the end that is outside?

    I think silicon would be your friend. A blob around the rj45 plug should waterproof it.

    Put the reader on an IP 65 Box. Run the cable into the IP 65 BOX.

    I could be wrong but thought network cables outside was a no no due to lightning strike.

    Most of the run will be in conduit but the end is the big worry

    [Both ordinary and direct burial CAT5 cables attract lighting strikes to some degree. Simply burying a cable underground does not lessen its affinity for lightning. Accordinly, CAT5 surge protectors should be installed as part of outdoor Ethernet networks to guard against lightning strikes.

    Plenty of fairly obvious information on the external runs already, so watch out for the RJ45 plug and the module you are plugging it into.
    These really need to be in a well sealed and water tight IP rated enclosure.
    Any sign of moisture and the contacts will begin to oxidise and you will soon have green gunge eating away at your contacts.
    Once you screw the lid down you want the air in there sealed in otherwise this will start to go down hill faster than you might think.

    I have around 30 Chip and Pin terminals that are in what are technically "kiosks" protected from the outside world by a roller shutter.
    Despite being out of the direct effects of the weather they all suffer from oxidisation and we have to maintain them once a year with white vinegar and silicon.
    The low voltages present on the Ethernet ports is enough to trigger it off.

    Surely you would drill a hole and feed the cable through and therefore the RJ45 would be on the inside of the building?

    Keep as much of it internal as you can and back feed to the external panels would be best otherwise run in conduit that has all the joints glued.

    Then there are speciality products such as:

    Ethernet Buccaneer. IP68 & IP69K Waterproof Cat5e Ethernet Connector system, by Bulgin Components.

    The automotive industry use 'dielectric grease' aka silicone grease(Silicone grease - Wikipedia, the free encyclopedia), I've used it on my ATV to protect electronics from corrosion & water damage. It can be wiped clean after use it will protect both sides (port and cable).
