This field termination jack is a slim, low profile breakout board for an RJ45 (8x8) jack (female) to screw terminals. The breakout board brings all 8 signal pins plus shield out to screw terminal blocks for easy termination or field wiring. This allows quick and simple connections for prototypes, field wiring or permanent installations. This jack is perfect for quick fixes on site where a punchdown jack is not an option.
