Single Piece Design. The S45-1501 is a single piece unshielded pass through RJ45 modular plug for use with unshielded LAN cables. No-load bar required. Supports performance standards: ANSI/TIA 568.2-D for Cat5e; ISO/IEC 11801 Class D; and applicable patch cord standards for Cat6 and Cat5e.3 Prong Pin Design with 50 of True 24ct Gold Plating. All Simply45 pass through RJ45 modular plugs uses only 50µ 24ct gold plated 3-Prong pin design instead of a 2-Prong design as found on most other pass-through RJ45 modular plugs. A 3-Prong pin provides 3 points of contact with the copper wire conductor instead of 2. This improves electrical performance and signal integrity. A 3-prong pin also holds stronger onto the wire conductors.Solid and Stranded LAN Cables. The S45-1501 is ideal for most Cat5e UTP (unshielded twisted pair) solid 24 AWG LAN cables and stranded 28-26 AWG with wire conductor sizes 0.95mm – 1.05mm (0.037 – 0.041). The S45-1501 works great with most Cat6 and Cat5e stranded unshielded LAN cables used on patch cords/leads. If stranded LAN cable has a larger diameter than 6.5mm (0.255), then S45-1600 or S45-1601 may be the right solution.Straight-Line Wire Insert. LAN cable wire conductors are easily inserted in a straight-line arrangement out through the front of the RJ45 pass through modular plug. The S45-1501 accommodates 24 AWG Solid and 28-26 AWG stranded LAN cable wire conductor sizes 0.95mm – 1.05mm (0.037 – 0.041. For larger UTP wire conductor sizes or larger LAN cable OD.Improved Crosstalk Performance. The unique internal design of the S45-1501 pass through RJ45 modular plug allows the LAN cable to be inserted further into the RJ45 plug. This reduces the length of untwisted wires improving NEXT performance. The S45-1501 accommodates most Cat5e LAN cables.
