Distinctive Characteristics
B
Subminiature size saves space on PC boards.
Specifically developed for logic-level
applications.
Totally sealed body construction
prevents contact contamination
and allows time- and money-
saving automated soldering
and cleaning.
Award-winning STC contact
mechanism with benefits
unavailable in conventional
mechanisms: smoother, positive
detent actuation, increased contact
stability and unparalleled logic-level
reliability. (Additional STC details in
Terms & Acronyms; see Supplement
section.)
Molded-in, epoxy sealed or ultrasonically
welded terminals lock out flux, solvents,
and other contaminants.
.100 x .100 (2.54mm x 2.54mm)
terminal spacing conforms to standard PC
board grid spacing.
Matching indicators available.
