8mm Process Sealed DIP Rotaries Series ND Distinctive Characteristics Sealed construction prevents contact contamination and allows automated soldering and cleaning. 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 automated soldering process. Crimped terminals ensure secure PC mounting and prevent dislodging during soldering. .100” (2.54mm) terminal grid spacing between pin centers, plus 3-by-3 terminal arrangement for footprint pattern equivalent to industry standard. Epoxy sealed terminals lock out flux, solvents, and other contaminants.

A cycle is one 360° rotation. 0.006Nm Nonshorting (break-before-make) Glass fiber reinforced polyamide Glass fiber reinforced polyamide (UL94V-0) Nitrile butadiene rubber Glass fiber reinforced polyamide (UL94V-0) Beryllium copper with gold plating Brass with gold plating Brass with gold plating –25°C through +75°C (–13°F through +167°F) 90 ~ 95% humidity for 96 hours @ 40°C (104°F) 10 ~ 55Hz with peak-to-peak amplitude of 1.5mm traversing the frequency range & returning in 1 minute; 3 right angled directions for 2 hours 50G (490m/s2) acceleration (tested in 6 right angled directions, with 5 shocks in each direction) PCB Processing Soldering: Wave Soldering Recommended: See Profile B in Supplement section. Manual Soldering: See Profile B in Supplement section. Cleaning: Automated Cleaning. See Cleaning Specifications in Supplement section. Standards & Certifications Flammability Standards: UL Recognition or CSA Certification: UL94V-0 rated housing & base The ND 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.
