The PLANET ISW-621T and ISW-621TS15 are compact industrial Ethernet switches designed for extreme temperature environments from -40 to 75 °C. These rugged switches feature four 10/100Base-TX ports and two 100Base-FX fiber ports – supporting either multimode (ISW-621T, up to 2 km) or single-mode (ISW-621TS15, up to 20 km) – for reliable connectivity in transportation, manufacturing, security, and surveillance systems.

Key Features:

– IP30-rated metal housing for DIN-rail or wall mounting
– 4 x 10/100Base-TX RJ45 with auto-negotiation and Auto-MDI/MDI-X
– 2 x 100Base-FX SC fiber interfaces
– ISW-621T: Multimode, 2 km
– ISW-621TS15: Singlemode, 20 km
