Standard and Miniature Single Assembly

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

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.

** Type numbers given are for binding posts with gold plated brass parts. For nickel plated brass parts add

suffix N, for tin plated brass parts add suffix T; for example, BP30GNN (nickel) or BP30GNT (tin). Order

single pack quantities by adding suffix “-1 PKG”, for example BP21R-1 PKG; order bulk pack quantities

by adding suffix “-B PKG”, for example BP21R-B PKG.
