Hardened Mini Industrial Switches.
Featuring a rugged industrial case, they’re particularly ideal for any
factory application where you need unmanaged switching between
multiple traffic segments. Or use them in power plants, mining and
military sites, or anywhere temperature and contaminants would
ordinarily wreak havoc on the switching circuitry.
multiple traffic segments. Or use them in power plants, mining and
military sites, or anywhere temperature and contaminants would
ordinarily wreak havoc on the switching circuitry.
The Hardened Mini Industrial Switches function at temperatures
ranging from 14º to 140° F (-10 to +60° C).
They’re also compact. They give you an affordable switching
solution for harsh environments where you have limited space for
networking hardware, such as in transportation cabinets on roadsides,
on shop floors, and in multi-tenant dwellings or fiber-to-the-home
(FTTH) applications.

on shop floors, and in multi-tenant dwellings or fiber-to-the-home
(FTTH) applications.
Plug and play, the switches don’t have any complicated software
to set up and run.
What‘s more, the Hardened Mini Industrial Switches can be DIN-
rail mounted (a mounting kit is included) and are equipped with
terminal block power input for use in industrial applications that
require Ethernet switching.

Eight versions are available: A copper-only switch with five
10BASE-T/100BASE-TX ports and six 4-to-1 copper/fiber optic switch-
es with four 10BASE-T/100BASE-TX ports and a 100BASE-FX fiber
port.

fiber
connectors for both multimode and single-mode connectivity. On the
LBH120A-H-75K-SC single-mode switch, interconnection between two
nodes can reach as far as 75 kilometers (46.6 mi.).

nodes can reach as far as 75 kilometers (46.6 mi.).
Because they perform standard autonegotiation and include
auto-MDI-X on the copper ports, they’re cost effective for integrating
legacy 10-Mbps networks with 100-Mbps Fast Ethernet networks.
The copper ports autonegotiate for 10- or 100-Mbps speed and
auto-detect full- or half-duplex mode.
