The N-Tron series NT24k managed Gigabit Ethernet industrial switch platform now has compact DIN-rail mountable switches. The all-Gigabit and Power over Ethernet Plus (PoE+) IEEE802.3af/at switches deliver wire-speed performance in harsh environments in which space may be limited. A compact NT24k hardened metal housing provides shock (200 g) and vibration (50 g) tolerance and an operating temperature range of -40 °C to 85 °C. All models feature N-ring technology with 30 ms recovery for rings containing up to 250 nodes.
