Noncontact Switching Comes to Confined Spaces

Mar 26, 2003


The Fairchild QVE00033 transmissive switch's small size, surface mount package and performance make it ideal for noncontact switching applications in disk drives, card detectors, mouse and trackballs, and motor and motion controllers.

In addition, optical, noncontact switching technology makes the QVE00033 more reliable, less expensive and more power efficient in many applications versus contact switches.

The QVE00033 comes in a temperature-resistant black plastic housing with a compact 7.50 x 4.05mm footprint and a 5.40mm package height.

A GaAs light emitting diode faces a silicon phototransistor across a 2mm gap with a 0.4mm aperture.

The peak transmission wavelength is infra-red at 940nm.

Surface mounting eliminates through-hole pins or wire leads and contributes to a lower profile.

A daylight filter on the phototransistor improves immunity to ambient light.

Collector current is between 100 and 600uA, maximum collector-to-emitter saturation voltage is 0.4V, operating temperature is -55 to +100C, and peak reflow-soldering temperature is 240C.
