NSM-205AFT-T Unmanaged Ethernet Switch, 4-port 10/100 + 1 Multi-Mode ST Fibre

NS-205AFT-T is an unmanaged Ethernet switch that combines four 10/100Base-TX RJ-45 ports with a single 100Base-FX multi-mode fibre port fitted with an ST connector. The fibre uplink carries 100 Mbps over distances of up to 2 km, and because the link is optical, electrical noise on the plant floor does not couple into the signal path.The unit accepts a wide +12 to +48 VDC supply through redundant power inputs, so it can run from the common DC voltages used in industrial automation without an external converter. Reverse polarity protection and a relay alarm output with a 2 A @ 30 VDC rating support straightforward power and fault monitoring. Broadcast storm protection is included.Mounting is on a DIN rail. The housing is plastic and the specified operating range is -30 °C to +75 °C, with storage between -40 °C and +85 °C. For the fibre link, the datasheet recommends 62.5/125 µm cable for full-duplex operation.ApplicationsIndustrial automation Ethernet networksFibre-based links between industrial network segments

NS-205AFC-T CR is an unmanaged Ethernet switch that combines four 10/100Base-TX RJ-45 ports with one 100Base-FX multi-mode fibre port terminated in an SC connector. The fibre link keeps electrical noise away from the signal path and extends reach to 2 km in full duplex, which suits connections between cabinets or buildings where copper would be unreliable.The switch accepts redundant +12 to +48 VDC supplies, so it can run from common industrial DC rails without an external converter. Reverse polarity protection and a relay alarm output rated 2 A @ 30 VDC help with fault monitoring on site.Store-and-forward processing, IEEE 802.3x flow control and broadcast storm protection support stable operation on small industrial Ethernet segments. Mounting is on DIN-rail, and the operating range is -30 °C to +75 °C.ApplicationsIndustrial Ethernet segments requiring a fibre link for noise immunityFibre uplinks between cabinets or buildings for Ethernet-connected equipmentInstallations with a 12 to 48 VDC power supply and no external converter

The NS-205AFCS-T CR is an unmanaged Ethernet switch that connects four RJ-45 copper ports (10/100Base-TX) to one single-mode fibre port (100Base-FX, SC connector). Fibre keeps electrical noise out of the link and supports distances up to 30 km, with 9/125 μm fibre recommended for full duplex operation.Power is supplied through redundant dual +12 to +48 VDC inputs with reverse polarity protection, so the switch can run from common industrial supply voltages without an external converter. A relay alarm output (2 A @ 30 VDC) and status LEDs help with monitoring.The plastic casing mounts on a DIN rail and is rated for an operating range of -30 °C to +75 °C. This ordering code is the single-mode 30 km SC variant of the NS-205 series.ApplicationsIndustrial automation networksLong-distance Ethernet links over single-mode fibreElectrically noisy environments
