NSM-208-M12 EN50155 8-port M12 Unmanaged Ethernet Switch, 10/100 Mbps

The NSM-208PSE-M12 is an unmanaged Ethernet switch for industrial networks where connectors must stay secure under vibration and shock. Each of its eight M12 ports acts as a Power Sourcing Equipment (PSE) port, supplying IEEE 802.3af compliant PoE of up to 15.4 W per port, so powered devices can be connected without a separate supply at each node.The switch is built to the railway standard EN50155, with EN50121-3-2 and EN50121-4 compliance, and also meets NEMA TS2. It accepts a +46 VDC to +53 VDC input with reverse polarity protection and offers 1500 Vrms isolation for one minute. Its metal casing is wall mounted and rated for operation from -40 °C to +75 °C.This listing includes eight M12D-4P-IP68 connectors and eight A-CAP-M12M caps, one M12A-5P-IP68 connector and one A-CAP-M12F cap, and the 4SIX1K0000003 wall mount kit.ApplicationsIndustrial Ethernet networks in harsh environmentsInstallations subject to high vibration and shockRailway applications requiring EN50155 compliancePowering IEEE 802.3af compliant PoE devices from a single switch

The NSM-208A is an unmanaged industrial Ethernet switch with eight shielded RJ-45 ports running at 10/100 Mbps. It suits engineers who need simple, plug-and-play connectivity for Ethernet devices in a cabinet without the configuration overhead of a managed switch. Each port auto-negotiates its speed and automatically handles MDI/MDI-X crossover, so straight or crossed cables can be used.Frames are buffered and forwarded using store-and-forward switching, supported by 768 Kbit of frame buffer memory and a 2048-entry MAC table. Full-duplex IEEE 802.3x and half-duplex back pressure flow control are both available. Per-port link and data-rate LEDs help with fault finding during commissioning.Operates from +12 ~ +48 VDC with reverse polarity protectionMetal casing rated IP30, designed for DIN-rail mountingOperating range of -40 °C ~ +75 °C with 10% ~ 90% RH non-condensing humidityApplicationsIndustrial Ethernet networking in DIN-rail mounted control cabinetsConnecting multiple 10/100 Mbps Ethernet devices in harsh-temperature environments

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-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
