PR-20

Surface Mountable Photo-reflector PR-20

Features

1.2.65(L)×3.35(W)× 0.95(H)mm

2.1mm

1.Dimensions: 2.65(L)×3.35(W)×0.95(H) mm, being extra thin and compact in size

2.The focal distance of 1mm enables the position sensing to be of high accuracy.

3.The adoption of the visible-light- cutting resin prevents the malfunction of the photo-reflecter,PR-20, which may be caused by disturbance light.

4.Reflow soldering available
