8mm Washable SMT DIP Rotaries
Series ND3
Distinctive Characteristics
Sealed construction prevents contact contamination and allows vapor
phase and IR reflow soldering. Sealed design accomplished with seals
between the actuator and housing and between housing and base.
Highly visible legends and choice of screwdriver or shaft actuation
to provide trouble-free code setting.
Detent mechanism designed for crisp, positive action
for accurate switch setting.
Bifurcated, spring loaded contacts give
unmatched logic-level reliability.
Heat tolerant resin used for body meets
UL flammability rating of 94V-0 and
maintains switch reliability through
vapor phase and infrared convection
reflow soldering.
Gull-winged terminals ensure mechanical
stability during soldering and simplified
solder joint inspection.
.100" terminal grid spacing between pin centers, plus 3-by-3 terminal
arrangement for pad layout pattern equivalent to industry standard.
Epoxy sealed terminals lock out flux, solvents, and other contaminants.
Coplanarity tolerance zone is 0.15mm (.0059") maximum, the allowable distance
between all considered surfaces in two parallel planes. (Additional details in Terms
and Acronyms; see Supplement Index page Z2.)

Standards & Certifications
Flammability Standards:
UL Recognition
or CSA Certification:
UL 94V-0 rated housing & base
The ND3 Series rotaries have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.
