The BT-CAT5-P1R-4870 Single-Port CAT-5 Midspan/Injector kit (also used as an PoE Passive Splitter) is a commercial grade Power-over-Ethernet device that provides DC power for one PoE-equipped device. It is compatible with Cisco Aironet? 1100 and 1200 series access points and other equipment supporting reverse polarity PoE pinout (Pins 4 and 5: Power - / Pins 7 and 8 Power: +).<br><br>Power-over-Ethernet eliminates the need for an AC outlet at each AP location. Only a single Ethernet cable is run to each AP instead of separate power and data cables. The injector is typically installed near the Ethernet hub.<br><br>The integral lightning and surge protection individually protects the 4 data lines as well as protection for the power lines. High speed devices clamp any voltage, positive or negative on the wires. The limits are +/- 15 volts on pins, 1, 2, 3, 6 and +/- 58 volts on pins, 4, 5, 7 and 8.<br><br>The BT-CAT5-P1R-4870 features shielded RJ45 jacks. This along with the BT-CAT5-P1R's metal housing helps reduce the effects of EMI interference. A ground lug and terminal is provided directly on the injector housing providing superior grounding. The cast aluminum housing includes integral mounting feet for ease of installation.<br><br>This kit includes the Injector and a 48VDC @ 70W power supply (PS4870-25R).<br><br>This unit is also available individually or in the following kits:<br><br>\injector only - BT-CAT5-P1R<br>With 48VDC @ 48 Watt Power Supply - BT-CAT5-P1 |
