Optical switch integrates IR emitter & NPN phototransistor

Designed for use in printers, copiers, scanners and for non-contact switching environments like a proximity sensor, the ITR1201 opto interrupter has been unveiled by EVERLIGHT ELECTRONICS. The reflective type ITR1201SR10A/TR is a light reflection switch which includes a GaAs IR-LED and an NPN phototransistor with a highly photosensitive receiver for short distances, operating in the IR range.

Key features include a fast response time, a very stable collector current, a cut-off visible wavelength of below 700nm and an improved MSL from 4 to 3.

Compared to the traditional glue dispense manufacturing process, double moulding results in a smoother surface which not only enhances the look but also raises the reliability. A flat profile of only 1.5mm makes the ITR1201 even more compact.

The ITR family is Pb-free and RoHS compliant. Samples and production quantities are available now.
