OPB960T11 Datasheet/PDFOptical Sensors - Photointerrupters - Slot Type - Logic Output
The OPB960T11 is an advanced photointerrupter optically coupled to an integrated phototransistor with logic output. The device functions as an optical switch, which senses the presence or absence of an object when the object interrupts or is exposed to light emitted from the LED side of the OPB960T11. This application field and working principle of the OPB960T11 is based on the optical detection of light transmitted through the slot-type sensor.
Application Field
The OPB960T11 is a highly efficient and economical device for a wide range of applications, as it can detect a target object from several millimeters away. The use of modern photointerrupters, such as the OPB960T11, in consumer applications has increased dramatically in recent years. It is primarily used in motion sensing, light curtains, mechatronics, and other close-distance sensing applications, but is gaining popularity as a machine vision solution for a variety of tasks, including inspection, inspection automation, and sorting. Some of the other common applications for the OPB960T11 include:
- Robotics.
- Position and speed control.
- Alarm and security systems.
- Material handling.
- Retail automation.
- Sensing presence of objects on production lines.
Working Principle
Theworking principle of the OPB960T11 is based on the optical detection of light transmitted through the slot-type sensor. When the object interrupts the light emitted from the LED side of the device, it triggers a logic low to the state output. The photointerrupter has an infrared LED as its emitting device and a bi-directionally-facing phototransistor as its detector element. The photointerrupter is able to detect the presence of an object by emitting a beam of light from the LED side and detecting the light that is reflected from the target on the opposite side. The sensing operation is triggered by the interruption of this infrared light, which produces a logic low on the output.
The OPB960T11 is designed for either AC or DC logic operation and can toggle logic states at high speeds. The device is also able to detect gaps or objects with varying widths, depending on the target object. Additionally, the sensor is temperature-compensated for increased accuracy, and its durability is enhanced through the use of ISOPLUS-7 insulation.
Conclusion
The OPB960T11 is an optical switch designed for motion sensing, light curtains, mechatronics, and other close distance sensing applications in a wide range of industries. The working principle of the device is based on optical detection of light transmitted through a slot-type sensor, and it has an infrared LED as its emitting device and a bi-directionally-facing phototransistor as its detector element. The OPB960T11 can detect the presence of an object from several millimeters away, can toggle logic states at high speeds, has temperature-compensated accuracy, and is built with an ISOPLUS-7 insulation.
