SCOTTSDALE, AZ--(Marketwire - May 20, 2008) - NKK Switches, the world's leading designer and manufacturer of innovative electromechanical switching devices, today announced the availability of the new FR series of 10mm Ultra-Thin DIP Rotary switches. The newly designed FR series replaces NKK's DR series rotary switches and incorporates the best characteristics of NKK's rotary devices and provides unprecedented quality and reliability for which NKK is renowned.

The FR series of binary coded DIP rotaries are environmentally friendly devices and meet the RoHS directive restricting the use of hazardous substances. The heat resistant resin materials are UL94V-0 and suited to lead-free solder processing applications including vapor phase and infrared convection reflow soldering for SMD option.

The FR series of DIP rotaries offer compact dimensions and a low profile allowing for high density mounting and close stacking of PC boards. Available in real or complement codes, decimal or hexadecimal configurations, the FR series can be specified in through-hole or SMD models. Highly visible and easy to read legends use arrows to indicate position and provide trouble-free code setting. Color-keyed actuators identify codes. Electrical capacity switching rating is 100mA @ 5V DC; nonswitching rating is 100mA @ 50V DC. The cam activated movable contact and gold contacts ensure contact reliability and continuity while the detent mechanism gives crisp, positive action providing accurate switch setting. Actuators are fully rotational and can be operated either clockwise or counterclockwise.

Through-hole devices can be specified with screwdriver or shaft actuators with straight or right angle mounts. Terminal spacing in straight PC through-hole is .100" between pins and .300" between rows. Packaging includes stick tube for through-hole versions and tape/reel for SMD. Right angle versions are available in two different footprints. The standard footprint is .100" between pins and .100" between rows. A new option of .100" between pins with .200" between rows is available to facilitate change over designs from DR series footprints. Crimped terminals ensure secure PC mounting and prevent the FR devices from dislodging during soldering.

SMD versions are straight mount with screwdriver actuators. Gull-winged terminals deliver mechanical stability during soldering and simplify solder joint inspection. The co planarity tolerance zone is .0059" (0.15mm) maximum, the allowable distance between all considered surfaces in two parallel planes. Optional snap-on knobs are available for screwdriver actuated models and feature a black knob with a transparent flange.
