Choosing a switch for an industrial networking fieldbus often comes down to a simple trade-off: buy a used unit with a known industrial model number, or buy a new unit that spells out the ports and features. That's exactly the choice between the N-TRON 708TX Industrial Ethernet Switch and the Industrial 6P Ethernet Switch w/Industrial DIN-Rail 1 SFP Port 12Gbps Capacity. Both fit the same job category, but they point in different directions. The N-TRON is a pre-owned switch from N-Tron, described as a networking device for industrial automation and motion control. The 6P switch is new, with a clearly described spec sheet and rugged credentials.
Quick verdict
For most buyers the decision starts with condition and specs. If you want a switch described as purpose-built for industrial automation and are comfortable with a used unit, the N-TRON 708TX is the straightforward choice. If you prefer a new unit with a clear port list and a rugged build, the 6P Ethernet Switch is the more complete package on paper.

|---|---|---|
| Price | USD 34.99 | USD 29.99 |
| Condition | Used | New |
Where each product wins
- N-TRON 708TX wins when your project centers on automation and motion control, and when a used switch is acceptable. Its N-Tron model number gives you a specific industrial part to reference.
- 6P DIN-Rail SFP Switch wins when you need new hardware, a defined set of connections, and mounting flexibility for cramped enclosures.
Product notes
N-TRON 708TX Industrial Ethernet Switch
N-TRON 708TX is the switch to weigh when your industrial networking fieldbus is built around PLCs and HMIs. It is described as a networking device for industrial automation and motion control, so its intended use is clear. If that matches your cabinet, this switch offers a direct, no-frills way to add Ethernet connectivity to the devices already on your floor. The main limitation is its condition: this unit is listed as used rather than new. For a replacement part in an existing setup, that can be a sensible trade-off. For a buyer who wants factory-fresh hardware, the alternative is the safer route. The N-TRON also keeps things simple as an industrial Ethernet switch designed for focused automation tasks, which is appropriate for many fieldbus layouts.
Industrial 6P Ethernet Switch w/Industrial DIN-Rail 1 SFP Port 12Gbps Capacity
If you're looking for a new switch with more upfront detail, the 6P Ethernet Switch is the option to read closely. It includes a 12Gbps switching capacity, four Gigabit Ethernet ports, an RJ45 uplink, and an SFP port, so the port layout is easy to plan around. It also supports automatic detection, full/half duplex, and MDI/MDI-X adaptive operation, which cuts down on cable-type confusion. The DIN-rail and wall-mount hardware is included, and the specified -40°C to 85°C operating range, IP40 protection, and 6KV lightning resistance suit outdoor cabinets and factory floors. The trade-off is its compact, six-port size: this is a local control-panel switch, not a high-density core switch for a large network. If your project needs exactly that small footprint, it's a strong match.
Final choice by use case
For a used replacement in an existing automation network, the N-TRON 708TX Industrial Ethernet Switch is the more targeted choice. For a new control-box install in a harsh environment that needs a rugged, space-saving switch, the Industrial 6P Ethernet Switch w/Industrial DIN-Rail 1 SFP Port 12Gbps Capacity is the one to buy.
