The BTD-CAT5-P1R Single-Port CAT-5 Midspan/Injector (also known as 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 BTD-CAT5-P1R features shielded RJ45 jacks. This along with the BTD-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.<br><br> This unit can be mounted to a DIN 3 rail using the DIN mounting clip located on the rear of the unit.<br><br> This kit includes the injector/tap and a 56VDC @ 117.6W power supply (PS56118-25R).<br><br> This unit is also available individually or in the following kits:<br><br> Injector Only - BTD-CAT5-P1R<br> With 48VDC @ 48 Watt Power Supply - BTD-CAT5P1R4848<br> With 48VDC @ 70 Watt Power Supply - BTD-CAT5P1R4870<br><br> |
