Pro-Tek5 PTI Ethernet Isolators

HALO Electronics Pro-Tek5 PTI Ethernet Isolators offer a convenient method of creating 5KV isolation to equipment located in an Ethernet cabling system. The Pro-Tek5 PTI includes Ethernet Isolators that are engineered to protect high-speed Ethernet links while maintaining full 10G performance. These isolators are IEEE802.3 compliant with enhanced insertion and return loss. UL-recognized reinforced insulation transformers are used to achieve a high level of isolation, with a minimum of 8.5mm of creepage and clearance. HALO Electronics Pro-Tek5 PTI Ethernet Isolators are available with or without mounting tabs.
