Leonton Technologies Industrial 802.3bt PoE Portfolio — Five Products for Demanding Network Deployments

Leonton Technologies, a Taiwan-based industrial networking design house, offers a tightly integrated portfolio of IEEE 802.3bt PoE products covering managed switches, media converters, and PoE injectors — all built for continuous operation in harsh industrial environments. This article covers four key models available at ipc2u.com, ranging from a high-capacity L3 managed switch with 10GbE uplinks to a compact 100 W PoE injector, each sharing a common design philosophy: wide-range DC power input, redundant supplies, –40°C to 75°C operating range, and Leonton's patented PoE management technologies.

Quick Comparison

BG5-1604-10GSFP-360 — L3 Managed 16-Port GbE 802.3bt PoE++ Switch with 10GbE Uplinks

Leonton BG5-1604-10GSFP-360 — 16-Port Industrial Managed Gigabit Ethernet 802.3bt PoE Switch

The BG5-1604-10GSFP-360 is a 16-port L3 managed switch offering 12 × 10/100/1000BASE-T ports with full IEEE 802.3bt PoE++ at 90 W per port, plus four SFP+ slots supporting 1G, 2.5G, and 10GbE transceivers. The total PoE power budget reaches 360 W, which comfortably supports high-draw devices such as PTZ cameras, Wi-Fi 6 access points, or AI-powered IP cameras across all 12 PoE ports simultaneously. The 104 Gbps non-blocking switching fabric ensures that PoE traffic and 10GbE uplink traffic do not contend for bandwidth.

The switch is positioned as a distribution or aggregation node in industrial network topologies where fiber uplinks carry traffic between distant locations. The four SFP+ ports accept standard 1G SFP modules as well as 2.5G and 10GbE transceivers, making it straightforward to scale uplink capacity as bandwidth demands grow — particularly relevant in AI machine vision installations that generate continuous high-resolution video streams.

Network resilience is handled through G.8032 ERPS v2 with sub-50 ms ring recovery alongside STP, RSTP, and MSTP. L3 static routing enables inter-VLAN forwarding without requiring a separate router in smaller network segments. Security capabilities include RADIUS, TACACS+, 802.1X port-based authentication, ACL, IP Source Guard, ARP Inspection, and SNMPv3. The switch accepts dual redundant 48–55 VDC power inputs and is rated for operation from –40°C to 75°C (extended temperature variant).

Leonton's Persistent PoE and PoE Ping Alive functions are implemented on this model. Persistent PoE maintains power delivery to connected PDs without interruption during switch configuration changes or software updates, while PoE Ping Alive automatically reboots an unresponsive powered device by cycling its PoE port — both features reducing the need for on-site intervention in remote or unmanned deployments.

BG5-1204-SFP-24 — L2 Managed 12-Port GbE 802.3bt PoE++ Switch, IEC 62443-4-1 Certified

Leonton BG5-1204-SFP-24 — 12-Port Industrial Gigabit IEEE 802.3bt PoE++ Managed Ethernet Switch

The BG5-1204-SFP-24 is a 12-port L2 managed industrial switch with a differentiated PoE architecture: four of the eight copper ports deliver full 802.3bt PoE++ at 90 W per port, while the remaining four operate at 802.3at PoE+ (30 W/port). The switch accepts a wide 12–55 VDC input range, which scales the available PoE budget from 90 W at 12 VDC up to 240 W at 36–55 VDC, allowing operators to match the power supply voltage to the total connected load without hardware changes. Four 100/1000BASE-X SFP slots provide fiber uplink connectivity.

The BG5-1204-SFP-24 holds IEC 62443-4-1 certification — a product development process standard that verifies the manufacturer's secure development lifecycle practices. For operators in critical infrastructure, utilities, or regulated industrial environments where cybersecurity compliance is a procurement requirement, this certification provides documented assurance alongside the standard security features: RADIUS, TACACS+, 802.1X, ACL, IP Source Guard, VLAN isolation, and SNMPv3 with multi-level CLI authorization.

Leonton's patented Safe PoE Disable function is included: it allows an operator to shut off PoE output on a port without removing network connectivity, enabling safe disconnection of powered devices during maintenance without affecting the switch's data plane. Combined with Persistent PoE, PoE Ping Alive, and an MTBF of 332,002 hours, the BG5-1204-SFP-24 is designed for facilities where unplanned downtime is operationally unacceptable.

MBG2-0201-SFP-24 — Industrial 802.3bt PoE Media Converter, 1× GbE PoE++ + 1× SFP

Leonton MBG2-0201-SFP-24 — Industrial IEEE 802.3bt PoE Media Converter

The MBG2-0201-SFP-24 is a two-port industrial media converter that bridges a fiber network segment to a single copper GbE PoE++ output. The SFP slot accepts any 100/1000BASE-X module, enabling deployments over single-mode or multimode fiber at whatever distance the application demands. The copper port delivers up to 90 W of IEEE 802.3bt PoE++ to the connected powered device, making it suitable for high-power endpoints such as PTZ cameras, AI inference appliances, or industrial wireless access points located far from the nearest copper switch.

Link Fault Pass-Through (LFP) propagates a fiber link-down event to the copper port, allowing the connected PD or a monitoring system upstream to react immediately to a loss of fiber connectivity rather than continuing to attempt communication on a broken path. This is particularly valuable in pipeline, rail, or perimeter security applications where rapid detection of infrastructure faults is operationally critical.

PD Remote Reset Technology (PRRT) is supported, enabling a management system to trigger a hard power cycle on the connected device over the network without requiring physical access. The unit is housed in a slim IP30 metal enclosure (30 × 95 × 75 mm) accepting dual redundant 12–55 VDC inputs, and is rated for the full −40°C to 75°C extended temperature range with an MTBF of 924,216 hours — the highest of any product in this lineup — reflecting the simplicity and robustness of its two-port architecture.

GINJ-0201-EBT-12-T — Industrial 100 W Enhanced 802.3bt PoE Gigabit Injector

Leonton GINJ-0201-EBT-12-T — Industrial Gigabit Enhanced 802.3bt PoE Injector

The GINJ-0201-EBT-12-T is a single-port industrial PoE injector that adds 802.3bt PoE++ capability to an existing GbE network port that does not natively support PoE. It accepts a standard Gigabit Ethernet data feed on one RJ45 port and delivers that data along with up to 100 W of PoE power on the output port — operating in Leonton's Enhanced PoE mode, which pushes beyond the standard 802.3bt maximum of 90 W to reach 100 W when the supply is at 24–55 VDC. This makes it the highest single-port PoE output device in Leonton's lineup and one of the few DIN-rail-mountable injectors to reach 100 W at industrial specifications.

In Standard PoE mode, the GINJ-0201-EBT-12-T is backward-compatible with 802.3af and 802.3at powered devices, negotiating the appropriate power level automatically. The wide 9–55 VDC input range with dual redundant power terminals allows it to be powered from common 12 V, 24 V, or 48 V industrial bus rails, and the input power booster ensures full PoE output even from lower supply voltages where the budget would otherwise be constrained.

The unit shares the same slim metal enclosure dimensions (30 × 95 × 75 mm) as the MBG2-0201-SFP-24 media converter, and like the rest of the Leonton PoE line it is DIN-rail and wall-mountable, rated to −40°C to 75°C, and certified to FCC/CE EMI and EMS standards with IEC 60068-2-6 vibration and IEC 60068-2-27 shock tests. The GINJ-0201-EBT-12-T is the practical choice when upgrading an isolated camera position or AI device attachment point to high-power PoE without replacing the upstream switch infrastructure.
