OPTEK Technology Develops Miniature Infrared Optoelectronic Sensor with Logic Output

SENSORS: TT Electronics’ OPTEK Technology has developed a small surface mount packaged photo light sensor with a digital output ideal for applications with limited space. Designated the OPL611 Series, the sensors feature data rates to 250kBaud and consist of a Photologic^® chip encapsulated in transparent molded plastic, providing optical coupling as well as mechanical protection.

The OPL611 Series surface mount sensors measure just 3mm x 3mm with a height of 1mm, and are mechanically and spectrally matched to OPTEK’s OP180, OP200, OP250, OP270 and OP280 Series infrared LEDs.

Available with buffer and inverter 10K internal pull-up as well as open collector outputs, the sensors feature a direct TTL/LSTTL CMOS interface. Minimum input power is 1.0mW/cm², V_CC ranges from 4.5 to 16V, and operating temperature ranges from -40 to +85C.
