Optical Sensors – Photointerrupters – Slot Type – Logic OutputOPB940L55 is an optically-coupled integrated circuit, which functions as a slot-type, logic-output photointerrupter used to detect the presence of objects in a confined area. The OPB940L55 can be used in a variety of applications such as conveyor-belt monitoring systems, presence detection, presence activation, feeder systems, and door or window alarms.The OPB940L55 is composed of two parts: an input LED (infrared emitter) and an output phototransistor. The infrared emitter is used to emit light onto the surface of the object being monitored. The output phototransistor is used to detect the presence of the object by blocking the light emitted from the LED. When the light is blocked, the phototransistor’s collector-emitter current will decrease, and an output indicating the presence of the object will be sent to the logic circuit.The OPB940L55 is designed to operate with a voltage of 5V and a current of less than 10mA. The output of the OPB940L55 is a logic signal that can be used to drive a logic circuit that can be used to activate an alarm or other event. It can be used with any logic family, such as TTL or CMOS. The output of the OPB940L55 is also capable of being used to connect directly to a microcontroller, which could be used to control various operations in the application.The OPB940L55 has a sensing distance of up to 15mm, and can be used to detect objects of any material or size. The device is designed to be incredibly reliable, and its switching speed can be adjusted depending on the application’s requirements. It can be used to accurately detect the presence of the object with a high degree of accuracy.The OPB940L55 is designed to be incredibly compact and is also very cost-effective. This makes it perfect for use in applications where space and cost are a major issue, such as conveyor-belt monitoring systems or presence detection for robots.In summary, the OPB940L55 is an ideal optically-coupled integrated circuit for a wide range of applications, such as conveyor-belt monitoring systems, presence detection, presence activation, feeder systems, and door or window alarms. The device has a wide range of operating parameters that can be adjusted to fit the needs of the application, making it especially well-suited for use in industrial applications. The OPB940L55 is also incredibly reliable and cost-effective, making it a great choice for use in applications that need to be space and cost-efficient.
