The PLANET ISW-621 and ISW-621S15 are robust, industrial-grade Ethernet switches designed for reliable operation in harsh environments. Both models feature four 10/100Base-TX copper ports and two 100Base-FX SC fiber ports. The ISW-621 supports multimode fiber for up to 2 km, while the ISW-621S15 supports single-mode fiber for up to 15 km. With their slim IP30 metal housings and extended voltage and temperature ranges, they are ideal for space-constrained applications in industrial automation, surveillance, and transportation.
