FEATURES AND SPECIFICATIONSSPECIIFICATIONS Molex's Mobile Phone Camera Sockets Offer Versatility for Mounting Camera ModulesThe mobile phone has become more than just an audio communication device over the past few years. With advances in cellular networks and camera modules, improved bandwidths have provided mobile phone manufacturers more options to include cameras and video-conference capabilities. Visual transmission is via the camera module connected to the camerasocket. The entire assembly is either soldered onto flex or PCB of the mobile phone. These sockets allow mobile phone makers to reduce their bills-of-material (BOM) due to the socket's compact design and simple assembly process. Another major benefit arising from the size of the sockets is the reduction in space.Molex offers a wide range of socket configurations that includes application extraction tooling to disengage the camera module from the socket.•Low profile •Excellent for Slim type cell phone •High reliability•Stable high quality image •Side contact and bottom contact solution •Options for module mating design •Top mount and mid mount solution •Provides various height options •Top cover available for •EMI and module holding •Module extraction tool available•Allows re-workCamera Sockets47249 8 x 8, Top Mount 47337 8.5 x 8.5, Top Mount47356 6 x 6, Mid Mount with Cap 47357 8 x 8, Mid Mount 47578 6 x 6,Top MountReference InformationPackaging: Embossed Tape on Reel UL File No.: Pending CSA File No.: PendingMates With: Respective camera module Designed In: mm Electrical Voltage: 50V Current: 0.5AContact Resistance: 60 milliohms max.Dielectric Withstanding Voltage: 150V AC Insulation Resistance: 400 Megohms min.MechanicalUnmating Force: 1.00N Durability: 30 cyclesPhysicalHousing: PA Polyamide (nylon), UL 94V-0Contact: Copper Alloy Plating:Contact Area —12 μ”Gold Solder Tail Area —Gold Underplating —Nickel PCB Thickness:Operating Temperature: -55°C to +85°CORDERING INFORMATIONVisit our Web site at MARKETS AND APPLICATIONS Order No. SNG-079©2007, Molex•Mobile phonesCamera Sockets47249 8 x 8, Top Mount 47337 8.5 x 8.5, Top Mount47356 6 x 6, Mid Mount with Cap 47357 8 x 8, Mid Mount 47578 6 x 6,Top MountDescriptionOrder No.Imager Dim.(mm)PCB Mounting Type Pitch (mm)CircuitsPhysical Size (L x W x H)in mmContact TypeCapacity (Mega Pixels)Camera Socket47578-0001 6 x 6Top0.65208.20 x 8.20 x 4.00Bottom0.30 MP (VGA)47356-0020 6 x 6Mid 0.65207.90 x 7.90 x 2.90Bottom0.30 MP (VGA)47249-00018 x 8Top 0.902410.10 x 10.10 x 4.20Side1 -2 MP (CMOS)47357-00018 x 8Mid 0.902410.18 x 10.18 x 3.35Side1 –2 MP (CMOS)47337-00018.5 x 8.5Top 0.902410.60 x 10.60 x 4.20Side2.0 MP (CMOS)Corporate Headquarters 2222 Wellington Ct.Lisle, Illinois 60532 USA 630-969-4550European Headquarters Munich, Germany 49-89-413092-0eurinfo@ Asia Pacific South Headquarters Jurong, Singapore 65-6-268-6868fesinfo@ Asia Pacific North Headquarters Yamato, Kanagawa, Japan 81-462-65-2324feninfo@ Americas Headquarters 2222 Wellington Ct.Lisle, Illinois 60532 USA 1-800-78MOLEX amerinfo@。
