SKU CH-KKJJ-MVRPX

Shielded RJ45 surge protector handles 10 GbE PoE with external grounding screw

  • ColorBlack
  • Protects PoE equipment using SAD and GDT technologies
  • Shielded RJ45 with external grounding screw for safe installation
  • Maintains 10 GbE data speed without signal degradation
  • Compatible with CAT5e, CAT6 and CAT6A cabling
  • Single-channel 10GbE PoE protection in compact form

Single-channel 10GbE PoE protection

The DITEK DTK-MRJPOES provides surge protection for a single Power over Ethernet line at up to 10 gigabits per second. Shielded RJ45 connectors preserve signal integrity while an external grounding screw allows a secure earth bond. It suits installers protecting PoE-powered cameras, access points or switches in commercial or industrial networks.

Thermals noise and power draw

As a passive inline device it adds no active cooling, fan noise or power consumption to the circuit. SAD and GDT components clamp transients without generating measurable heat during normal operation. The unit simply passes PoE current and data while diverting surge energy to ground.

Build integration requirements

The protector fits between the Ethernet cable and the powered device using standard RJ45 patch leads. CAT5e, CAT6 and CAT6A cabling are all supported without performance loss. It does not supply power itself, so a PoE injector or switch must already exist upstream. Buyers needing multi-channel protection or fibre interfaces should look elsewhere.

Questions about this item

How is the external grounding screw connected during installation?

The shielded RJ45 protector includes an external grounding screw that must be bonded to the building grounding system; the step often missed is securing a low-impedance ground wire to that screw before plugging in the data cable.

Which component degrades first and requires replacement after repeated surges?

The internal SAD and GDT suppression elements absorb transient energy and will eventually wear out after multiple large surge events, so the whole unit should be replaced once it has taken a significant hit.

What is the maximum sustained data rate before signal degradation appears?

The device is rated for 10 Gigabit Ethernet throughput and maintains signal integrity up to that speed; sustained traffic at or below 10 GbE will not cause degradation.
