983-MF-2.8 /-4,8
Tab/Screw Connector Block
With tabs
DESCRIPTION
Tab/screw connector blocks 983-MF-2,8 and 983-MF-4,8 in 10 mm pitch are available in 2- to 12-pole design and can be mounted side-by-side in nominal pitch. These connectors are based on our series 983 terminal strips. The lead connection is designed as head contact terminal with M3,5 screws. Screws and square washers are movably connected. The square washers are mounted in a non-twist arrangement. For an easier connection of the lead, the washer automatically moves up when the screw is loosened. One tab connection per pole with widths of 2,8 or 4,8 mm is located on the solder/tab side. That way, current transmission to other components is possible without using printed circuits.
