This unmanaged industrial ETHERNET switch (852-111/000-001) has 5 ETHERNET ports for easily setting up small- to medium-sized networks. Its slim design paired with a DIN-rail adapter simplifies installation in the control cabinet and provides high vibration and shock resistance. Additionally, automatic transmission rate detection (auto-negotiation) and automatic identification of the transmit and receive lines (Auto MDI-X) allow simple plug-and-play operation, saving time and money during commissioning. Features: 5 ETHERNET ports 10/100 Mbit/s Autonegotiation Front-panel diagnostic LEDs Supports Auto-MDI/MDI-X functions Full/half-duplex transfer modes for each port Store-and-forward switching method Integrated address look-up table, supports 2000 absolute MAC addresses Overvoltage protection IEEE 802.3x flow control in full-duplex mode Prioritization of PROFINET data packets (EtherType=0x8892) per IEEE802.1p DIN-35 rail mounting
