Series ND3 8mm Process Sealed SMT DIP Rotaries General Specifications Electrical Capacity (Resistive Load) Switching Rating: 100mA 5V DC Nonswitching Rating: 100mA 50V DC Other Ratings Contact Resistance: 80 milliohms maximum for circuit 30 milliohms maximum for contact point Insulation Resistance: 1,000 megohms minimum 250V DC Dielectric Strength: 250V AC minimum for 1 minute minimum Mechanical Life: 20,000 detent operations minimum Electrical Life: 20,000 detent operations minimum Note: A detent operation is one actuator position operation or stepping. 20,000 detent operations = 1,250 cycles for hexadecimal devices or 2,000 cycles for decimal devices. A cycle is one 360 rotation. Nominal Operating Torque: .061 kgf/cm (.846 oz/in) Contact Timing: Nonshorting (break-before-make) Materials & Finishes Actuator: Glass fiber reinforced polyamide Housing: Glass fiber reinforced polyamide (UL94V-0) O-ring: Nitrile butadiene rubber G Base: Glass fiber reinforced polyamide (UL94V-0) Movable Contact: Beryllium copper with gold plating Stationary Contacts: Brass with gold plating Terminals: Brass with gold plating Environmental Data Operating Temperature Range: 25C through +85C (13F through +185F) Humidity: 90 ~ 95% humidity for 100 hours 40C (104F) Vibration: 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 2 Shock: 50G (490m/s ) acceleration (tested in 6 right angled directions, with 5 shocks in each direction) Processing Soldering: Reflow Soldering: See Profile B in Supplement section. Note: During Reflow Soldering process, set the switch to the following position: ND3FR10, ND3FR16, ND3KR10, ND3KR16: 0 position ND3FC10, ND3KC10: 7 position ND3FC16, ND3KC16: F position. Manual Soldering: See Profile B in Supplement section. Cleaning: Automated cleaning. See Cleaning Specifications in Supplement section. Standards & Certifications Flammability Standards: UL94V-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.

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. G Gull-winged terminals ensure mechanical stability during soldering and simplified solder joint inspection100 (2.54mm) 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. Packaging in tape-reel or partitioned tray. Tape-reel packaging meets EIA-481-2 Standard. Coplanarity: all considered surfaces must lie between two parallel planes that are a maximum distance apart of .0059 (0.15mm).
