Surge protector for POE ++ and Category 6A cabling network
Part Number: 581518
MJ8-POE-B
- POE++ compatible (IEEE 802.3bt)
- 10G compatible from 5m to 100m in the channel, using Cat-6A S/FTP cabling
- RJ45 Shielded connectors
- IEC 61643-21, EN 61643-21
- Indoor application: IP20 rating (NEMA 2)
- Plastic enclosure, UL94-V0
- Location and test categories: D1, C2, C3
The MJ8-POE is designed to protect sensitive data-processing equipment
connected to a POE (Power over Ethernet) network from transient
overvoltages.
The MJ8-POE surge protector is deployed in signal network applications
with data transmission speeds of 100 and 1000 Mbps.
The surge protector is housed in a shielded enclosure with high quality
RJ45 shielded jacks.
The transient protection circuit is based on high energy gas discharge
tubes (GDT) and a network of fast response silicon avalanche diodes
(SAD) to achieve sharp clamping of very large surge events.
