Overview
INJ 2100-T PoE Injectors are DIN Rail mounted single port, PoE mid-span injectors. In environments vulnerable to voltage surges, it acts as an intermediary devices between a non-PoE switch and a PoE device to inject fully compliant power over the Ethernet cable. With electrical isolation of the internal power supply, the INJ-2100-T units are protected against short circuits on the PoE side. The integrated surge protection increases system availability by protecting the connected end devices.
Generating up to 60 Watts, the INJ-2100-T provides electrical power to remote PD access points, pan-tilt and zoom (PTZ) cameras and video-phones. It complies with the IEEE802.3bt Hi-PoE (60W of power) or IEEE 802.3at PoE+ (30W of power) standards and is also backward compatible with IEEE802.3af PoE (15.4W of power). Learn more about PoE.
With the INJ-2100-T, there is no need to buy an expensive PoE switch or install electrical wiring and outlets in hard to reach locations. Just use and open port on an existing non-PoE switch to save time and money by sending power and data over the same cable.
INJ-2100-T Injector Benefits
|
DIN Rail Enclosure |
Easily mount on a DIN rail or inside distribution boxes using native DIN Rail enclosure with grounding clip. No need for add-on brackets. |
|
Power Over Ethernet (PSE) |
Performs the Power Sourcing Equipment ( PSE ) function on 1 UTP port for IEEE 802.3af (up to 15.4 watts PoE), IEEE 802.3at ( up to 30 watts PoE+ ) or IEEE802.3bt (up to 60 watts Hi-PoE) compliant devices. |
|
Electrical isolation of the internal power supply unit |
The supply voltage and Power over Ethernet port are electrically isolated. This provides optimum protection against short circuits in the data cables on the field side. The passive network isolator protects Ethernet devices from potential differences of up to 4 kV.
|
|
On-board PoE Power Controller |
This PoE power controller provides compliant power provisioning and monitoring, properly sensing through signature detection whether or not the attach Ethernet devices are PoE capable or not. This provides a safe connection for both PoE and Non-PoE capable devices. Click here for more details |

Advanced Power Management |
|
|
Integrated Surge Protection |
The integrated surge protection protects the devices and the application against sudden high voltages in the field data cables. The injector and the downstream devices are protected against over-voltages that can arise via Port 2 (the PoE-conducting port). The surge protection function is done in accordance with CAT5e for data rates of up to 1GB. |
|
Potential Separation |
Safe shield connection to ground potential |
|
Shield current monitoring |
The cable shield current monitoring can be used for diagnostics. An LED indicates if there are differences in potential or other shield currents caused by EMC. The LED lights up in the event of cable shield currents greater than +30mA and less than -30mA on the PoE-conducting port. The LED may flicker or flash because the shield currents are not constant. Customer can reduce the equipotential bonding across the data lines by laying the equipotential bonding lines between the individual installation sites separately. |
|
Potential Separation |
Safe shield connection to ground potential |
|
Multiple connection technologies |
For greater flexibility and time savings during installation you can choose between IDC, Push-in, Screw connections.
|
|
Covered cable wiring space |
A hinged cover protects the wiring space on the field cable side with connection terminal blocks and shield contacting. This ensures a uniform installation pattern. In addition to this visual extra, the sensitive connection wires are protected from external influences |
|
Quick tool-free shield connection with no loose parts |
The cable shielding can be connected to the device quickly and easily without tools – with strain relief assured at the same time. Simply lay the cable in the shaft provided, close the shroud and, you’re done. |
