P6448 is a photoreflector consisting of a light modulation photo IC and an infrared LED, etc. The light modulation photo IC allows reliable
operation even under background disturbance light.
Features
l Compact size (35 10 17 mm)
l Detection distance: 30 cm Typ.
l Allowable background light level: 2000 lx Min.
Applications
l Reflective optical switches

*1: Distance between P6448 and reflective paper (reflectivity 90 %) when the photo IC output level changes to L while bringing the
paper close to P6448 operated with H level output. (The photo IC has hysteresis characteristics, so the distance when the output
changes from L to H is longer than that when the output changes from H to L.)
*2: No direct light source within field of view.
