Figure 5.6 - Rj45 Contact Assignment; Table 5.2 – Pin Assignment Skd02-T And Plug Contact Rj45 - Samcon ExCam IPM1145 User Manual

The standard pin assignment of the SKD02-T in accordance with EIA/TIA-568B for
100BaseTX with PoE (IEEE 802.3af/at) is as follows:
Pin / Potential
Mode A Mode B
Tx+ / PoE ±48 VDC Tx+
Tx- / PoE ±48 VDC Tx-
Rx+ / PoE GND Rx+
n.a. PoE +48 VDC
n.a. PoE +48 VDC
Rx- / PoE GND Rx-
n.a. PoE GND
n.a. PoE GND
shield/ GND
(complete conductor bunch)
shield
(single, twisted pair pins)
Particularly in EMC critical environments, it is important to earth the shield at the terminal
block side (q.v. figure 5.3 – pin with black shrink tubing and blue ferule).
