Disconnect terminals provide a quick,
reliable method of connection to termi-
nal blocks and boards without the use
of tools. They are supplied in a variety
of styles to meet virtually all quick-dis-
connect requirements. Female discon-
nect terminals and matching male tabs
accommodate a range of 22-10 AWG,
and are available in non-insulated, par-
tially insulated, and fully insulated
styles, in both nylon and vinyl. They are
available in various tab widths including
.250", .187", and .110", and a combina-
tion size. A unique construction of the
female disconnect offers long-term
dependability. The brazed seam serrat-
ed barrel provides maximum tensile
strength.
