|NKK presents its ultra-thin rotary switches. Where previous versions of SMT FR Series devices were only available with screwdriver actuation, the FR02 version enables more convenient hand actuation, while still retaining the ability to be adjusted with a flat tipped screwdriver. With a height of just 3.8mm, FR Series devices also deliver the lowest profile in the industry and allow close stacking of PC boards. Environmentally friendly components and packaging materials meet RoHS directive restricting use of hazardous substances.
These switches are suited to lead-free solder processing applications because of their heat resistant resin materials. Slim 0.150" (3.8 mm) body has the lowest profile in the industry and allows close stacking of PC boards. Highly visible legends and choice of screwdriver or shaft actuators with arrow position indication provide trouble-free code setting. Detent mechanism gives crisp, positive action for accurate switch setting. Use of heat resistant resin allows vapor phase and infrared convection reflow soldering. Crimped terminals for through-hole models ensure secure PC mounting and prevent dislodging during soldering. Gull-winged terminals for SMT models ensure mechanical stability during soldering and simplified solder joint inspection. Cam-activated, movable contact and gold contacts assure contact reliability and continuity. Datasheet
