Reflective Optical Sensor Sets Integration Benchmark January 13, 2005
Operating at distances from 2 mm to 40 mm, the 6 mm x 3.76 mm x 3.9 mm, surface-mount TCND5000 reflective optical sensor integrates an IR emitter and PIN photodiode in a single package. The device is suitable for use with object presence, touch, and proximity sensors in a variety of consumer, industrial, and automotive applications. Optical axes of the emitter and detector rely on parallel alignment for optimal reflective operation. The IR emitter operates over a 950-nm wavelength and in conjunction with a 950-nm IR band-pass filter that eliminates interference from daylight. Other features include an optical barrier between the emitter and detector that significantly reduces crosstalk levels. Pricing in 50,000-piece quantities starts at $75 per 100 pieces.
