NS-208 Unmanaged 8-Port Industrial Ethernet Switch, 10/100Base-TX

The NSM-108 is an unmanaged industrial Ethernet switch with eight shielded RJ-45 ports, each supporting 10/100Base-TX with automatic speed negotiation and automatic MDI/MDI-X crossover. Engineers can connect devices without worrying about cable type or port wiring, which simplifies commissioning on plug-and-play networks.Every port has its own frame buffer and uses store-and-forward processing, so frames are fully received and checked before being forwarded. Flow control is negotiated on each link, using IEEE 802.3x in full duplex and back pressure in half duplex. Link and data rate LEDs on each port help with troubleshooting in the field.The unit accepts a wide +12 VDC ~ +48 VDC supply with reverse polarity protection and draws 0.15 A at 24 VDC. Its metal casing is rated IP20 and can be mounted on a DIN rail or on a wall. The NSM-108 operates from -40 °C to +75 °C, which suits cabinets in demanding industrial environments.ApplicationsIndustrial Ethernet networks

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

NS-208-M12-IP67 is an unmanaged 8-port 10/100 Mbps Ethernet switch built for industrial networks where connectors must stay sealed and secure. Each port uses a female 4-pin shielded M12 D-coded connector rated IP67, and the M12 locking design suits installations exposed to high vibration and shock.The switch operates in store-and-forward mode and auto-negotiates speed on every port. It supports IEEE 802.3, 802.3u and 802.3x, with full-duplex operation, half-duplex backpressure flow control and automatic MDI/MDI-X crossover, so cabling does not need to be matched to the port type. Its 1500 Vrms isolation rating and reverse polarity protection add margin for demanding installations.The wide +12 VDC to +53 VDC input covers the common power standards used in industrial automation, removing the need for an external power converter. The unit is supplied with eight M12D-4P-IP68 connectors, eight A-CAP-M12M caps, one M12A-5P-IP68 connector and one A-CAP-M12F cap. Operating temperature is -10 °C to +60 °C with IP67 protection, or -40 °C to +75 °C with IP66 protection.ApplicationsIndustrial Ethernet networks in harsh environmentsInstallations subject to high vibration and shockIndustrial automation systems with 12 to 53 VDC supplies

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
