Mini Industrial 3-Port 10/100/1000T + 1-Port 100/1000X SFP PD Switch with PoE Splitter Function
Product Overview:
The LNK-IMC103G-SFP-PD is a compact industrial-grade PD switch with
integrated PoE splitter functionality, designed for flexible
network deployments in space-constrained and power-limited
environments. This versatile device features 3× 10/100/1000BASE-T
RJ45 ports and 1× 100/1000BASE-X SFP fiber optic slot, providing
both copper and fiber connectivity options.
The dedicated "PoE IN" RJ45 port accepts IEEE 802.3af/at compliant
power input from remote PSE switches or PoE injectors, eliminating
the need for local power supplies while delivering 5-24V DC output
(max 3A, 60W) to connected devices. The auto-adapting SFP port
supports both 100Base-FX and 1000Base-X optical modules, enabling
long-distance fiber extension of copper networks.
With DIN-rail mounting capability and optional L-bracket for wall
or flat surface installation, this switch is ideal for industrial
automation, outdoor surveillance, intelligent transportation
systems, and other applications requiring reliable connectivity in
harsh environments where both power availability and space are
limited.
