Small green PCB with four RJ45 ports and screw terminal blocks, DIN rail clip, 35 mm rail mount

SMUGDESK

SMUGDESK 4 Port RJ45 Industrial Ethernet Breakout Adapter

SKU CH-MZEZ-H0A04

Industrial Ethernet breakout adapter converts four RJ45 ports to screw terminal blocks for tool-free hard wiring on 35 mm DIN rails with ESD and surge protection

Specification 4 port

  • Converts RJ45 to screw terminals for tool-free wiring
  • ESD and surge protection maintains signal integrity in harsh environments
  • DIN rail clip enables quick 35 mm rail mounting
  • Locking screw terminals resist vibration-induced loose connections
  • Passive design works with PLCs, switches and servo drives

Industrial Ethernet Breakout Adapter

This SMUGDESK adapter converts a single RJ45 Ethernet jack into four 8-pin screw terminal blocks, allowing direct hard-wiring of twisted-pair cables without crimping tools or patch cords. It is built for PLC technicians and cabinet builders who need reliable field terminations inside control panels.

Sustained Load Behaviour

Integrated ESD and surge suppression components protect signal integrity against voltage spikes and electromagnetic interference common in production workshops. The passive, power-free design maintains stable data transmission during continuous operation, while high-tension locking screws resist vibration-induced loosening on long-running equipment.

Upgrade Path

Replaces improvised terminal strips and crimped patch cords that degrade under vibration and temperature cycling. The jump is worth it when installing or servicing PLCs, industrial gateways, IP cameras or remote I/O modules on 35 mm DIN rails where tidy, tool-free wiring changes reduce downtime.

Highlights

  • Converts RJ45 to screw terminals for tool-free wiring
  • ESD and surge protection maintains signal integrity in harsh environments
  • DIN rail clip enables quick 35 mm rail mounting
  • Locking screw terminals resist vibration-induced loose connections
  • Passive design works with PLCs, switches and servo drives

Questions about this item

Does the adapter generate heat or noise when it passes data continuously?

The unit is a passive breakout board with no active components, so it produces no audible noise and negligible heat during continuous operation.

What cable type and tools are needed to connect field wiring to the screw terminals?

You supply solid or stranded twisted-pair wires and a small screwdriver; the lockable screw terminals accept both single-core and multi-core conductors without crimp tools.

Will it fit on the 35 mm DIN rail already used in my control cabinet?

Yes, the built-in buckle clips directly onto standard 35 mm DIN mounting rails for quick, secure installation.
