NS-208A Unmanaged 8-Port Industrial 10/100 Mbps Ethernet 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 NS-208AG is an unmanaged Ethernet switch with eight shielded RJ-45 ports, each supporting 10/100/1000 Base-T. Ports negotiate speed and flow control automatically, so an engineer can connect eight workstations or devices without manual configuration. Automatic MDI/MDI-X crossover means straight or crossover cabling can be used.The switch uses a store-and-forward architecture with a 4096-entry MAC table and 1.5 Mbit frame buffer memory. It supports 9K jumbo frames at 1000 Mbps and provides both IEEE 802.3x and back pressure flow control. A per-port link and data rate LED helps with troubleshooting.Power is supplied from +12 VDC to +48 VDC with reverse polarity protection. The plastic housing is designed for DIN-rail mounting and operates from -40 °C to +75 °C. The NS-208AG is CE, UKCA, FCC, RoHS and WEEE certified.ApplicationsConnecting up to eight workstations or devices in small Ethernet segmentsDIN-rail mounted control cabinet networking

The NS-208 CR is an unmanaged industrial Ethernet switch providing eight shielded RJ-45 ports for 10/100Base-TX networks. Each port negotiates its speed automatically and detects crossover wiring itself, so devices can be connected without special cables or manual configuration.Frames are buffered and forwarded using store-and-forward processing, and the switch supports both IEEE 802.3x full-duplex flow control and back-pressure flow control in half-duplex mode. A per-port link and activity LED, plus power and speed indicators, help with commissioning and fault finding.Designed for DIN-rail mounting, the switch accepts a +12 to +48 VDC supply with reverse polarity protection and operates from -40 to +75 °C. It suits engineers who need a simple, dependable Ethernet backbone inside control cabinets without the setup overhead of a managed switch.ApplicationsIndustrial Ethernet networking in DIN-rail control cabinetsConnecting 10/100Base-TX devices in automation and machine control systems

The NS-208-IP67 is an unmanaged Ethernet switch for industrial networks where equipment is exposed to dust, moisture, vibration and shock. Its eight RJ-45 ports use locking-style IP67 connectors, so cabling can be installed without a separate enclosure around the switch.Each port auto-negotiates 10/100 Mbps and selects full or half duplex automatically, with MDI/MDI-X crossover handled in the switch itself. The store-and-forward architecture, 1024-entry MAC table and 512 Kbit frame buffer memory support wire-speed switching for typical plug-and-play device networks.The ordering code includes the IP67 RJ-45 plugs, caps with tether and an IP67 power plug. Protection is rated IP67 from -10 to +60 °C and IP66 from -40 to +75 °C, so check the operating range against your installation before specifying the unit.ApplicationsIndustrial Ethernet networks in harsh environmentsInstallations subject to high vibration and shockConnecting remote devices on machines and production lines in exposed locations
