Optical Sensors are used to detect the presence and absence of a target object. One of the most commonly used optical sensors is Photointerrupters, which are used to detect an object or a signal using light. Slot Type photointerrupters are used specifically to detect objects using the interruption of an infrared light beam. H22LTB is a type of Slot Type photointerrupter with logic output, and it is widely used in various application fields.

The H22LTB photointerrupter has a built-in slotted optical switch with a built-in photo amplifier. The photo-diode detector sits inside a slot, while the collector and emitter pins sit outside the slot on both sides of the detector. The emitter emits infrared light which is detected by the photo-diode of the detector when an object passes through the slot. The detected signal is then sent to the photo amplifier, which amplifies the signal and outputs it via the collector pin.

H22LTB photointerrupter is equipped with built-in regulator circuits to supply a stable current to the emitter and the photo-diode, ensuring reliable operation. It also features a built-in detector amplifier to make sure the maximum output impedance of the collector is 0.3V and the minimum output impedance is typically 7V. Moreover, H22LTB has a wide potential range from 4V up to 30V to provide flexibility in the operation.

H22LTB photointerrupter is widely used in various application fields due to its reliable operation and excellent performance. It is widely used in automotive industries, where it is used to detect the presence of a target object in the engine or vehicle. It is also used in industrial machines to detect the presence of a part or object, as well as in home appliances to detect the motion of a hand or foot. In addition, H22LTB photointerrupter is often used in home automation systems to detect when someone is entering a room.

When it comes to H22LTB photointerrupter’s working principle, it relies on the interruption of an infrared light beam. The emitter emits the infrared light beam, which is detected by the photo-diode of the detector when an object passes through the slotted optical switch. The detected signal is then sent to the photo amplifier, which amplifies the signal and outputs it via the collector pin. This signal can then be used to detect the presence or absence of a target object.

To summarize, H22LTB is a type of Slot Type photointerrupter which has a built-in slotted optical switch with a built-in photo amplifier and a built-in detector amplifier. It is widely used in various application fields, such as automotive and industrial machines, home appliances, and home automation systems. The working principle of H22LTB photointerrupter is based on the interruption of an infrared light beam, which is sent from the emitter and detected by the photo-diode of the detector, before being outputted via the collector pin.
