Reflective Optical Sensor with Transistor Output

DESCRIPTION

The TCNT2000 is a reflective sensor in a miniature SMD

package. It has a compact construction where the emitting

light source and the detector are arranged in the same

plane. The operating infrared wavelength is 940 nm. The

detector consists of a silicon phototransistor. The sensor

analog output signal (photo current) is triggered by

detection of reflected infrared light from a close by object.

The sensor has a built in daylight blocking filter, which

greatly suppresses disturbing ambient light and therefore

increases signal to noise ratio.

FEATURES

• Package type: SMD

• Detector type: phototransistor

• Dimensions (L x W x H in mm): 3.4 x 2.7 x 1.5

• Operating range within > 20 % relative collector

current: 0.2 mm to 5 mm

• Emitter wavelength: 940 nm

• Moisture sensitivity level (MSL): 3

• Material categorization: For definitions of compliance

APPLICATIONS

• Position sensor

• Optical switch

• Optical encoder (e.g. disc and tape drives for DVD and/or

camera applications)

• Object detection (e.g. paper presence in printer and copy

machines)
