D‑Link DIS‑100E‑05 – Small, Affordable, and Built for the Rough Stuff

What’s new?

D‑Link has added a fresh entry to its industrial portfolio: the DIS‑100E‑05 unmanaged switch. At just 3.9 × 3.0 × 1.2 inches (99 × 76 × 30 mm) and 1.45 W power draw, it is one of the smallest Ethernet switches you can mount on a DIN rail. The device offers five RJ45 ports, each limited to 100 Mbps Fast Ethernet. While the bandwidth ceiling looks modest, the switch compensates with a suite of durability features:

• Operating temperature: –40 °F to 167 °F (‑40 °C to 75 °C)
• Surge protection: up to 6 kV per port
• Power options: barrel connector or a voltage‑flexible terminal block accepting 12–55 V from two independent sources (power‑redundancy)
• Energy‑efficient Ethernet: IEEE 802.3az compliance reduces idle‑power consumption
• IP40 housing: protects against solid objects larger than 1 mm, but not against dust or water
• EMI hardening: mitigates interference in noisy industrial settings
• Fan‑less design: eliminates moving parts, further increasing reliability

The switch is unmanaged, meaning it ships ready‑to‑use with no configuration required.

How does it compare?

Feature	DIS‑100E‑05	Typical 5‑port unmanaged Gigabit switch (e.g., Netgear GS105)
Max port speed	100 Mbps	1 Gbps
Power consumption	1.45 W	2–3 W
Operating temp. range	–40 °F – 167 °F	0 °F – 104 °F
Surge protection per port	6 kV	4 kV (often unspecified)
Power redundancy	Dual input (12‑55 V)	None
Size (L × W × H)	3.9 × 3.0 × 1.2 in	4.5 × 4.5 × 1.2 in
IP rating	IP40	IP20‑IP30
Management	Unmanaged	Unmanaged

The most obvious trade‑off is speed. Modern office networks typically run at Gigabit, but many industrial sensors, PLCs, and legacy equipment still communicate over 100 Mbps. In those scenarios the DIS‑100E‑05’s lower power draw, extended temperature range and dual‑voltage input become decisive advantages.

Who should consider it?

• Factory floor integrators who need to connect legacy PLCs, barcode scanners or temperature sensors that only speak Fast Ethernet.
• Transportation and rail projects where space is at a premium and equipment must survive sub‑zero temperatures and high‑heat engine bays.
• Remote monitoring stations powered by solar or battery packs; the 12‑55 V input lets you feed the switch from a wide variety of DC sources without additional converters.
• Field service technicians who need a plug‑and‑play switch that can be mounted on a DIN rail and left unattended for months.

If your deployment demands true Gigabit throughput—high‑definition video streams, large data‑log transfers, or modern IoT gateways—the DIS‑100E‑05 will quickly become a bottleneck. In that case a rugged Gigabit switch such as the Moxa EDS‑105A or Hirschmann RS10 would be more appropriate, albeit at a higher price and larger footprint.

Pricing and availability

D‑Link lists the DIS‑100E‑05 at ≈ €85 (≈ $92) per unit. The product is currently stocked by a handful of European distributors; North‑American channels have not announced shipments yet. Expect lead times of 2–3 weeks for bulk orders.

Bottom line

The DIS‑100E‑05 is not a replacement for mainstream office switches, but it fills a niche that many industrial vendors overlook: a tiny, low‑cost, fan‑less switch that can survive extreme temperatures, handle voltage swings, and protect against surges. For anyone building rugged sensor networks or retrofitting legacy equipment, it offers a pragmatic balance of durability and price.
