The OPB491L11Z is a slot type, logic output optical sensor with numerous applications in industry and home automation. It consists of an infrared light-emitting diode (LED) and a phototransistor, both mounted together in a single package. The OPB491L11Z is designed for detection of an object passing through the slot. It is typically used in applications which require detection of an object passing through a defined space, such as conveyor systems, card feeders, paper feeders, and consumer appliances.

The OPB491L11Z is a highly reliable optical sensor, and it has been designed to minimize the possibility of false detection due to interference from ambient light or other environmental factors. It is designed to minimize crosstalk and interference from adjacent sensors, and features a signal output voltage that is very stable over time and operating temperature.

The working principle underlying the OPB491L11Z is based on the use of light-sensitive devices to detect an object passing through the slot. When the slot is empty, the gap between the LED and the phototransistor is blocked, preventing the LED from emitting light. When an object passes through the slot, it breaks the beam of light and the phototransistor detects the light, which in turn triggers the output signal. The output signal generated by the sensor is detected by an external electronic circuit, which then acts accordingly.

The OPB491L11Z is typically used in a variety of applications, such as card feeders, paper feeders, and consumer appliances. It can also be used to detect the presence or absence of an object in a specified region, such as a conveyor system. Its logic output feature makes it ideal for use in automation systems. The OPB491L11Z is also able to detect objects with great accuracy, thanks to its high signal-to-noise ratio and low dark current. Finally, its wide operating temperature range of -40°C to +85°C makes it ideal for use in industrial applications, where it can withstand extreme temperatures.

In summary, the OPB491L11Z is an optical slot type, logic output optical sensor ideal for use in industrial and home automation applications. Its working principle is based on the use of light-sensitive devices to detect the presence or absence of an object passing through the gap. It is highly reliable and features a wide operating temperature range of -40°C to +85°C.
