China Best 12.0mm Barrier Terminal Blocks which enable conversion from a screw-type format of wiring terminals to a higher pitch row of female connectors. To compensate for the larger spacings between the screw-type format of screw wiring terminals, the screw-type wiring terminals can be arranged in first and second rows, either staggered or not, one on each side of the row of female connectors. Individual female connectors in the row are connected alternatively with a screw wiring terminal from the first row and a screw wiring terminal from the second row.
These interconnecting Barrier Terminal Blocks are suitable for use with all thermocouple types as well as Copper for other sensors such as RTDs. Every single block comes complete with terminal lugs and end caps. All are color coded as shown for easy identification and are temperature rated to 425ºF.
