Distinctive Characteristics
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 contents.)
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.
Toggle option in antistatic material available for
dissipating electrostatic discharges.
Matching indicators available.
