Everlight reveals ITR photo interrupter
Keywords:photo interrupter? infrared emitting diode?
The ultra small outline 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, added the company.
Everlight's ITR products consist of an infrared emitting diode and an NPN silicon phototransistor,
integrated by a double moulding process. This unique process claims to reduces 74 per cent 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 ITR1205ST11A/TR has an even more compact size than
conventional parts, stated the firm. By using an advanced packaging technology, the 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.
The ITR photo interrupters are Pb/Halogens-free and RoHS compliant.
