PLANET 4+2 100FX Port Multi-mode Industrial Ethernet Switch

The PLANET ISW-621 and ISW-621S15 are compact, rugged industrial-grade Ethernet switches designed for reliable networking in harsh environments. With 4 Fast Ethernet copper ports and 2 fiber SC ports, these switches are perfect for applications requiring both short (ISW-621, up to 2km via multimode) and long-distance (ISW-621S15, up to 15km via single-mode) transmission. Their slim IP30 metal housing supports DIN-rail or wall mounting, making them ideal for space-constrained industrial setups.

Key Features:

• 4 x 10/100BASE-TX RJ45 ports with auto MDI/MDI-X
• 2 x 100BASE-FX SC fiber ports:
• ISW-621: Multimode, up to 2km (50/125 µm)
• ISW-621S15: Singlemode, up to 15km (9/125 µm)
• Switching Fabric: 1.2 Gbps, Store-and-Forward architecture
• High resistance to EMI, ESD, and power surges
• Dual redundant power input (12–48V DC) with failover alarm
• Operating temperature: -10 to 60 °C
