NSM-208A Unmanaged 8-Port Industrial 10/100 Mbps Ethernet Switch, Metal Case

The NS-208A CR is an unmanaged industrial Ethernet switch offering eight shielded RJ-45 ports for 10/100Base-TX connections. Each port negotiates its speed automatically and detects crossover automatically, so cables can be connected without worrying about wiring order during commissioning.Every port has its own memory buffer and uses store-and-forward switching, which helps ensure frames are passed on intact. Flow control is negotiated per link, using IEEE 802.3x in full duplex and back pressure in half duplex. A link and data rate LED on each port makes it quicker to spot faults on a live network.The switch is built for DIN-rail installation in a plastic housing and has reverse polarity protection on its +12 ~ +48 VDC supply input. It is suited to cabinets where a simple, low-maintenance Ethernet switch is needed rather than a managed platform.ApplicationsConnecting 10/100 Mbps Ethernet devices in DIN-rail mounted industrial control cabinets

The NSM-208AG CR is an unmanaged Ethernet switch with eight RJ-45 ports, each supporting 10/100/1000 Base-T operation. Each port negotiates its speed automatically between 10, 100 and 1000 Mbps, and the flow control mechanism is negotiated alongside it, so the switch adapts to each connected device without manual configuration.Store-and-forward processing and automatic MDI/MDI-X crossover make the switch straightforward to deploy in a mixed network of workstations and devices. Link, data rate and power LEDs help with commissioning and fault finding at the port level.The metal casing is rated for an operating temperature of -40 °C ~ +75 °C and can be mounted on a DIN rail or on a wall. The +12 VDC to +48 VDC input includes reverse polarity protection, and the port isolation is rated at 1500 Vrms for 1 minute.ApplicationsConnecting up to eight workstations or devices in Ethernet networksIndustrial communication networks requiring a compact, DIN-rail or wall-mounted switch

The NSM-208-M12 is an unmanaged, store-and-forward Ethernet switch with eight 10/100 Mbps M12 D-coded ports. It suits engineers who need a robust, plug-and-play network backbone without configuration overhead. Each port auto-negotiates its speed and automatically handles MDI/MDI-X crossover.The switch is EN50155, EN50121-3-2, EN50121-4 and NEMA TS2 compliant. Its wide 12 to 53 VDC input accepts common industrial supply voltages without an external converter, which simplifies installation. Reverse polarity protection is fitted, and the metal casing is rated IP40 for wall mounting.The order code NSM-208-M12 CR includes eight M12D-4P-IP68 connectors, eight A-CAP-M12M caps, one M12A-5P-IP68 connector and one A-CAP-M12F cap.ApplicationsIndustrial Ethernet networks in harsh environmentsInstallations subject to high vibration and shockIndustrial applications requiring a wide-input DC supply

The NSM-208GP is an unmanaged eight-port Gigabit Ethernet switch that also acts as a PoE power sourcing equipment (PSE). Each RJ-45 port supplies up to 30 W to a powered device under IEEE 802.3at, so one switch can feed several remote devices without a separate injector on every port.Power comes from a redundant dual input accepting +24 to +53 VDC, with reverse polarity protection. The PoE stage is boosted internally, so PoE applications can run from a 24 VDC supply rather than a 48 V supply.The switch uses store and forward processing, with a 4 K MAC table, 1.5 Mbit frame buffer and jumbo frame support up to 9 K. An independent PoE status LED on each port helps engineers spot faults quickly, and a relay alarm output is provided. The metal casing mounts on DIN-rail or, optionally, on a wall, and the unit is rated for -25 °C to +75 °C.ApplicationsPowering PoE devices from a 24 VDC supply without a separate 48 V supplyIndustrial Ethernet network infrastructure
