Surge Protectors

CATx Surge Protector

CATx Surge Protector
SP-CAT5-6V
  • Protects sensors running on CATx unshielded twisted pair (UTP) cable against the effects of electrostatic discharge, faulty wiring and lightning.
  • The use of two protectors on each end of the line will provide increased protection for each end against surges.
    • Total length of CATx cable between the surge protector and ENVIROMUX-MINI-LXO, ENVIROMUX-MICRO, or sensor should not exceed 25 ft (7.62 m).
  • Protected pins: (1,2) (3,6) (4,7) and (7,8) pass through.
  • Impedance: 85 to 115 Ohms
  • Surge suppression: 22Vpeak @ 100A 10/1000µs
  • Maximum continuous voltage: 6Vpeak
  • Dimensions WxDxH: 1x3.6x0.9 in (25x91x23 mm)
  • Compatible with ENVIROMUX-MINI-LXO and ENVIROMUX-MICRO.
  • Regulatory approvals: GR 1089, NEC 800.100 and 830.100, ITU 703, UL94 V0 Flame Rated.
