Integrating GaAs IR LED emitter, silicon NPN phototransistor, and photosensitive receiver optimized for short distances, ITR1201SR10A/TR reflective type opto interrupter offers cut-off visible wavelength of below 700 nm. Double molding manufacturing process results in smooth surface that promotes reliability. With flat, 1.5 mm profile, reflective sensor offers stable collector current and is suited for use in printers, copiers, and scanners as well as non-contact switching environments.
