工业企业越来越多地使用unmanaged switches to connect edge devices for Industrial Internet of Things (IIoT) applications. These switches enable Ethernet devices, ranging from surveillance cameras to sensors, to reliably stream data for aggregation and analysis.
When evaluating unmanaged switches, it’s important to ensure switches planned for use on the plant floor are hardened to withstand extreme temperatures, humidity, vibration, dust, chemical substances, and electromagnetic interference.
Antaira, a manufacturer of industrial networking and communication products, has released its latest unmanaged switch models featuring Power over Ethernet (PoE)—the LNP-0800G and LNP-0800G-24. Housed in rigid, IP30-rated DIN-rail metal cases, these fanless switches deliver long-term reliability in harsh industrial settings, including extreme applications where temperatures range from -10°C to 65°C (LNP-0800G) or -40°C to 75°C (LNP-0800G-24). Both support eight Gigabit Ethernet connections with 30W per port PoE+ (802.3af/at) power for remote devices. The switches also support 9.6Kbytes Jumbo Frame to improve network performance by making data transmissions more efficient.
Store-and-forward transmission capabilities in both switches ensure minimal collisions and frame errors, while high EFT (electrical fast transient) and ESD (electrostatic discharge) protection prevents interference in automation or other high electromagnetic environments.
The key difference between LNP-0800G and LNP-0800G-24 switches is that the LNP-0800G-24 supports dual 9-55V DC power inputs for power redundancy, while the LNP-0800G has a range of 48-55V DC for basic power requirements.
In other Ethernet switch-related product news, Antaira has now integrated persistent PoE technology into its 802.3bt PoE managed switches. This technology ensures power is continuously carried to powered devices during firmware upgrades so that data collection is not terminated. It also prevents connected devices from rebooting once power is restored.
Other Antaira products featuring persistent PoE technology include the LMP-1204G-SFP-bt, LMP-0702G-SFP-bt and LMP-C602G-SFP-bt managed switches. These switches feature a mix of 6 to 12 Ethernet and SFP fiber ports combined with 802.3bt PoE++ to deliver up to 90W per port.
