Optical Sensors are components designed to detect the presence of electromagnetic radiation. They use photoelectric, photocoupled and other techniques to respond to the energy within a range of output power levels. In particular, Photointerrupters, which represent a variation of optical sensors, use optical technology to detect the presence of a physical object. This type of interrupter can be classified further into different categories which include Slot Type Logic Output.

The OPB491T11Z Photointerrupter is a specific type of Slot Type Logic Output interrupter. It is a through-beam type having a detector and transmitter arranged in a single package, separated by a gap. A slot in the package interrupts the light beam when an object passes through the gap. The detector emits a logic output indicating a presence or absence of an object from the slot. It has a high sensitivity of upto 90mA and its response times are approximately 0.5ms.

In terms of operation, the OPB491T11Z uses a Light Emitting Diode (LED) which radiates infrared light to the receiver, inverted from the transmitter, separated with a gap. The emitter transmits light in an optimized space size suited for this component, and also conforming to EIAJ standards. This type of interrupter functions by measuring the interrupting pattern of the light when the physical object breaks the beam of light. The receiver it is combined with then processes the signal and provides a logic output indicating the presence or absence of an object in the slot.

Applications of the OPB491T11Z are wide and varied, and include office automation and industrial automation. In particular, this type of interrupter is used in the detection and measuring of objects passing through a gap, which can help in applications like paper feeding, product or part counting, and positioning or alignment control. This model can also be used for proximity sensing in a conveyor, presence sensing in home electrical appliances, position sensing in a packing machine, and detection in a mailing machine.

The OPB491T11Z is an advanced photointerrupter with a logic output for a variety of applications. Its high sensitivity and fast response times make it ideal for use in automation and office equipment. Applications for this photointerrupter range from presence sensing in home appliances to paper feeding in document processing machines. It is a versatile and reliable component for any system requiring accurately detected light interruptions.
