For design engineers with the requirement for a compact infrared sensor, 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.

“Not only are the Photologic sensors small, robust and economical, but the hysteresis characteristics of the Schmitt trigger on each device gives them exceptionally high noise immunity,” said Rodney Bailey, vice president of optoelectronic component solutions for OPTEK Technology.  “These design characteristics make the Photologic sensors ideal for use in a variety of sensing applications, including machine automation and safety, assembly line automation, non-contact reflective object and interruptive sensing, as well as end-of-travel, object, and paper sensing.”

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, VCC ranges from 4.5 to 16V, and operating temperature ranges from -40°C to +85°C.
