Another key feature is the IDC connection technology for the tool-free IDC connector. This SPE connector comes in two parts that can easily be harnessed in the field without using any additional tools. After stripping the cable, the two wires are to be inserted into the cable manager. The wire can be trimmed to length using a standard cutting tool; the strain relief is now able to be closed. Snap the cable manager and the second part of the connector together; done. An audible click signals the connector has locked safely in the right way. The connector comes in a robust metal housing with metal snap-in hooks and supports wires from 22 to 26 AWG with an outer diameter ranging from 4.5 to 7.5 mm.
