5-WAY
®
Binding Posts have positive-stop captive
thumbnuts that allow space to make connections
yet reduce the likelihood of accidentally contacting
current carrying parts. They are available in red,
white, blue, yellow, black and green. BP31 fluted
nut types have insulating parts of Lexan
®
polycar-
bonate resin which has a higher DC insulation re-
sistance at all operating temperatures and signifi-
cantly lower capacitance which provides greater
resistance to high frequency leakage effects. All
others have nylon plastic per MIL-P20693A, Type
IV. Current carrying parts are gold, nickel or tin
plated brass for improved conductivity and corro-
sion resistance. Metal parts are recessed for user
and instrument protection and none touch the
mounting panel. All are available in single packs or
100-quantity bulk packs. They are Underwriters
Laboratories recognized components.
