Construction and Working Principle

The construction of a slotted opto-transducer is relatively straightforward, yet highly effective. It involves mounting an infrared emitting diode and a silicon phototransistor on opposite sides of a piece of opaque plastic that features a slotSlotted optical switch. The infrared LED emits a beam of light, which travels across the slot to the phototransistor. When the light beam is uninterrupted, the phototransistor is illuminated and conducts electricity. However, when an object is introduced into the slot, it breaks the light beam, causing the phototransistor to stop conducting.Solved 1.
