The 852‐1305 Industrial Managed Switch is an 8-port 10/100/1000Base‐TX and 4-port SFP-100Base‐SX/LX configurable ETHERNET switch (SFP modules are optional).

Packaged in a rugged housing, this switch offers both a redundant power supply and relay-based function monitoring. These functions, along with extensive ETHERNET switch options, make it ideal for a wide range of applications.


  • Web-based/SNMP Management
  • Redundant DC power supply
  • Wide supply voltage range: 12 … 60 VDC
  • DIP switches to set alarm functions
  • Fully compatible with IEEE 802.3, 802.3u, 802.3z, 802.3x, 802.3ad, 802.3ab, 802.1d, 802.1q, 802.1p, 802.1w, 802.1x standards
  • Xpress Ring (redundant ring, recovery < 50 ms)
  • Non‐blocking, store‐and‐forward switching, rapid spanning tree protocol (RSTP)
  • Autonegotiation at all 10/100/1000Base-T ports
  • Auto‐MDI/MDIX (crossover) at all 10/100/1000Base‐T ports
  • VLAN (802.1q) VID
  • IGMP snooping for multicast filtering
  • Port configuration, status, statistics
  • Port trunking
  • SNMP v1/v2 and RMON
