Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...
The device actuates when an object interruptsthe infrared LED packaged in the device, which can be driven with dc forward current up to 50 ma. Maximum reverse dc voltage is 5 V, and maximum power ...
The switch has an infrared LED and phototransistor housed in a right-angle plastic package that lets an opaque object block the light beam from multiple directions, including the X, Y, and Z axes.
