The Simply45 S45-1605P 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 Cat6 and Cat6a; ISO/IEC 11801 Class E and Ea. Supports 10GBaseT performance applications over unshielded twisted pair cables. Cap45 is an isolation cap/bar that snaps onto the front of the pass-through RJ45 plug after termination, covering the exposed wire ends. Cap45 is fast and easy to use. Fits all compliant RJ45 sockets. With Cap45, any electrical risks associated with pass-through RJ45 modular plug exposed wire ends are now eliminated completely. If you don't want to use Cap45, no problem. It will not affect plug performance. You just won't have the Cap45 benefits.
The Simply45 ProSeries introduces the exclusive Cap45 (PATENT 10,811,831 B1). Cap45 is an isolation cap/bar that snaps onto the front of the pass-through RJ45 plug after termination, covering the exposed wire ends. Cap45 prevents electrical shorting in the RJ45 socket due to improperly trimmed wires or in device sockets that may not be 100% compliant. With Cap45, any electrical risks associated with exposed wire ends are now eliminated completely.
Cap45 is a MUST-HAVE for all pass-through RJ45 modular plugs used in commercial and certified system terminations.
