Description:

Each of these devices consists of a NPN silicon phototransistor mounted in a miniature SMT package with a 0805 size chip carrier that is compatible with most automated mounting and position sensing equipment.

Both OP500, OP500DA and OP501, OP501DA have a flat lens. OP501 and OP501DA has an opaque lens that shields the device from stray light, whereas OP500 and OP500DA has a water clear lens. All devices have a wide viewing acceptance angle and higher collector current than devices without lenses especially on the OP500DA and OP501 which incorporate photo darlington die instead on the standard transistor.

Features:

? High photo sensitivity

? Fast response time

? 0805 package size

? Phototransistor or Photo Darlington Output

? Choice of opaque or water clear flat lens

Applications:

? Non-contact position sensing

? Datum detection

? Machine automation

? Optical encoders
