Hornet 4+1 Port Ethernet Switch

Hornet 4+1 Port Ethernet Switch

Moog Protokraft Hornet series 10/100/1000Base-T unmanaged Ethernet switches consist of 5x10/100/1000Base-T ports with autonegotiation and auto MDI / MDIx functions integrated into a bulkhead mounted MIL-DTL-38999 connector assembly. The external interface of the Hornet is a D38999 size 19-35 connector with 4x IEEE-802.3U:2005 10/100/1000Base-T compliant Ethernet ports. The internal interface of the Hornet is a ribbon coax cable to Samtec® SMT connector assembly enabling interconnection to a motherboard, daughtercard or backplane. Power to the unit is supplied through the Samtec® connector.
