The Hirschmann Spider II 8TX (P/N: 943957-001) is an unmanaged Entry Level Industrial ETHERNET Rail-Switch that features store and forward switching mode, Ethernet (10 Mbit/s) and Fast-Ethernet (100 Mbit/s), 8 x 10/100BASE-TX, TP-cable, RJ45 sockets, auto-crossing, auto-negotiation & auto polarity. It features a space saving design and is intended for use in small networks. It has a very efficient power consumption, making the Spider II 8TX a cost effective addition to a network.

  • Plug & play capability
  • Shock & vibration resistant
  • Resistant to electromagnetic interference (EMI)
  • Auto polarity - If the receive line pair is incorrectly connected (RD+ and RD- switched) polarity is automatically reversed.
  • Auto-negotiation - a procedure in which the switch automatically selects the operating mode of its 10/100 RJ-45 ports.
  • Auto-crossing - automatically configures its port for the correct transmit and receive pins
  • LEDs indicate port status
