Optical Sensors - Photointerrupters - Slot Type - Logic Output

The OPB493P11 is a mechanically and optically robust and reliable logic-output type slot-type optical photointerrupter from the OPB493 series of products. It features a wide gap between the emitter and receiver that allows a broad range of objects to pass through it. The logic signal output is high when the object breaks the beam, and low when the object is broken, allowing for easy response to the break in the optical path.The OPB493P11 product is composed of an infrared emitter and a photosensitive receiver in a single package. The emitter emits infrared radiation, while the photosensitive receiver detects the interruptions of the infrared radiation. The signal output is controlled by the emitter and receiver, and is only generated when the object breaks the beam.The working principle of the OPB493P11 is based on the photoelectric effect. When an object interrupts the infrared radiation between the emitter and the receiver, the incident radiation energy decreases, thus altering the output voltage from the receiver. This voltage change causes the output signal to switch from low to high, or vice versa.The OPB493P11 can be used to detect a range of objects, such as objects moving through a machine, open doors, electronic products, and so on. Any object that is able to break the outgoing beam in the desired area within the range of the device can be detected.Additionally, the device is designed to operate under a wide range of environmental conditions, including temperatures, humidity, shock, and vibration. This makes it suitable for industrial applications, as it can handle harsh industrial environments.The device has numerous advantages, such as fast response time and high switching speed. Moreover, it has low power consumption, as it only requires a voltage of 1.2–5.5 V, and its pulse-width modulation can be easily adjusted to accurately detect any object passing through it.Finally, the OPB493P11 slot-type optical photointerrupter is RoHS2 compliant, making it safe for use in a variety of industrial and consumer applications. Additionally, it has undergone rigorous testing and is certified for use in high-temperature applications, further increasing its reliability for both general and special applications.
