Product details
Structured cabling that leaves a building - to a gatehouse, a camera pole, an outbuilding or a rooftop access point - brings surges straight back into the switch. The DEHNpatch DPA M CLE RJ45B 48 sits in that link, protecting all four pairs to class E performance up to 250MHz while passing Power over Ethernet up to PoE++.
Key features
- Protects all four pairs with gas discharge tubes and a filter matrix per pair
- Cat 6 in the channel, class E performance up to 250MHz with 3dB insertion loss
- Power over Ethernet compliant to IEEE 802.3 up to PoE++ / 4PPoE
- Fully shielded zinc die-cast body, earthed via the 35mm DIN rail
- RJ45 socket in and out, so it retrofits into an existing link without re-terminating
Typical applications
Fit it where a copper Ethernet link crosses between buildings or goes outdoors: external CCTV and ANPR cameras, wireless access points on roofs and masts, gatehouse and barrier controls, car park and lighting controllers, industrial Ethernet runs between plant areas, and any PoE device mounted outside the equipotential zone of the main building.
Compliance
Tested to IEC 61643-21 / EN 61643-21 and UL 497B, with CSA, UL, GHMT and EAC approvals. Earthing is made through the 35mm DIN rail to EN 60715. Suitable for installation at lightning protection zone boundaries from 0B-2 and higher.
