Everlight Unveils Ultra-small Outline ITR Photo Interrupter for Optical Switches, Digital Cameras and Printers

Shulin, New Taipei City - EVERLIGHT ELECTRONICS CO., LTD. [TSE:2393], a leading player in the global LED and optoelectronics industry with three decades of experience, has introduced the latest member of its ITR series of photo interrupters for use in optical switches, digital cameras and printers, the ultra small outline slotted type ITR1205ST11A/TR. A slotted type opto interrupter detects an object when it enters the gap of the slotted switch and blocks the light path between the emitter and detector.

Everlight's ITR Products consist of an infrared emitting diode and an NPN silicon phototransistor, integrated by a double molding process. This unique process reduces 74% volume in dimension as compared with conventional photo interrupter product in the market. The phototransistor detector receives light from the IR LED only, and avoids the noise from ambient light.

With a low profile of only 2.7mm, the new ITR1205ST11A/TR has an even more compact size than conventional parts. By using an advanced packaging technology, Everlight's ITR1205ST11A/TR can be designed to have a gap and slit width of 1.1mm and 0.3mm respectively, thus enabling it to have a higher degree of accuracy or detection sensitivity. This high degree of accuracy is especially needed for digital camera applications. Everlight's ITR photo interrupters are Pb/Halogens-free and RoHS compliant.
