The PLANET ISW-621TF is a slim-form industrial Fast Ethernet switch with robust IP30 housing, designed to operate in wide temperature environments from -40 to 75 °C. Featuring four 10/100Base-TX RJ45 ports and two 100Base-FX SFP slots, it supports flexible fiber connections from 2 km (multimode) up to 60+ km (single-mode), making it ideal for transportation, surveillance, and industrial networking.

Features:

– IP30-rated metal enclosure for DIN-rail or wall mounting
– 4 x 10/100Base-TX RJ45 ports with Auto-MDI/MDI-X
– 2 x 100Base-FX SFP slots (LC) for multimode/single-mode fiber modules
– Store-and-Forward architecture with 1.2 Gbps switching fabric
– 2K MAC address table, 1 Mbit frame buffer
