TT Electronics OPB930 and OPB940 Photologic Optical Switches
TT Electronics OPB930 and OPB940 Photologic Optical Switches are manufactured from opaque-grade injection-molded plastic housings that minimize the assembly's sensitivity to visible and near-infrared ambient radiation. The OPB930 and OPB940 optical switches can be specified with either 8.9mm L Series long pins or 610mm W Series wire leads. These optical switches have a maximum supply voltage of 10V and operate in a temperature range from -40°C to +70°C. The OPB930 and OPB940 optical switches are ideal for various applications, including edge sensing, mechanical limit indication, mechanical switch replacement, and speed indication.
