Reflective Photosensors (Photo Reflectors)
CNB1301 (ON2171)
Reflective photosensor
Non-contact point SW, object sensing
■ Overview
CNB1301 is a reflective photosensor consisting of a small, thin
reflective photosensor (CNB1302) to which a plastic lens is attached to
increase the focal distance from 0.8 mm to 2.5 mm.
■ Features
• Small size, light weight: 5 mm × 4.5 mm (height: 4.0 mm)
• Focal distance: 2.5 mm
• Visible light cutoff resin is used
■ Applications
• Copier
• Facsimiles
• Printers
• Cassette deck
■ Absolute Maximum Ratings T_a = 25°C
