Corn Electronics RJ45 Surge Protector 100M Ethernet Network

SKU CH-FYKR-DZMZD

Protects 10/100 Mbps Ethernet gear from lightning surges with a 5 V, 5 kA RJ45 unit in a shielded 83×25×25 mm aluminium housing

  • Protects network gear from lightning surges with 5 kA discharge capacity
  • Maintains 100 Mbps throughput with only 0.5 dB insertion loss
  • Responds to transients in 1 nanosecond to shield connected equipment
  • Shielded aluminium alloy housing resists EMI for reliable signal integrity
  • Compact 83 × 25 × 25 mm design installs inline within one metre of device

Purpose and placement

The Corn Electronics RJ45 surge protector shields Ethernet equipment from lightning strikes and power surges on 10BaseT and 100BaseTX networks. It is intended for installations where a single cable run enters a building or crosses between structures. Home offices, small business routers, switches, hubs and repeaters all benefit from the added protection layer. The device mounts inline within one metre of the protected port for best results.

Build and daily handling

A shielded aluminium alloy housing measures 83 by 25 by 25 millimetres and carries clearly marked IN and OUT RJ45 ports plus a grounding wire. Insertion loss is rated at 0.5 dB and response time at 1 nanosecond, so 100 megabit throughput remains unaffected. The compact block fits behind a patch panel or on a desk without blocking adjacent ports. Grounding the wire to a verified earth point completes the installation in seconds.

Upgrade context and limits

This protector replaces an unprotected patch cord or a basic coupler that offers no surge clamping. The jump is worthwhile whenever a cable runs outdoors, between floors or near electrical panels where transients exceed 15 volts. It does not serve gigabit or 10 gigabit links, so networks faster than 100 megabits need a different device. Buyers who require Power over Ethernet pass-through or multiple protected ports should look elsewhere.
