Optical Sensors - Photointerrupters - Slot Type - Logic Output

OPB960N55 is a product from Opto 22 that is part of their optical sensors product line. This photointerrupter sensor is a slot-type photo interrupter that features logic output photocouplers in a space saving package. OPB960N55 is capable of accurately detecting a slot of an object passing through its beam axis with speeds up to 121 cm/s.The OPB960N55 has two components, an emitter (LED) and a receiver (photo transistor). The receiver essentially produces a current in response to the transmitter\'s infrared signal, which produces a binary output. It has an operating temperature range of -25° to +80°C.The OPB960N55 provides fast optical sensing with low power consumption. It is made up of two components and is available in various packaging styles to fit the application requirements of the user. The design of the sensor allows it to detect the passage of an object across its beam axis with accuracy.The OPB960N55 is a versatile optical sensor suitable for a wide range of applications, from material handling equipment to safety and security equipment. Applications include: • Detection of items passing through a passageway • Detecting the presence of parts on a conveyor• Alignment and registration in manufacturing processes• Position sensing • Verifying the presence of components in an assemblyThe OPB960N55 is designed to operate as a monostable type optical switch, detecting and inhibiting the passage of a slot in an object. It does this by using a combination of an emitter and receiver module that detect the passage of the slot. When the slot passes between the emitter and receiver, the photo transistor inside the receiver conducts current, which switches the output of the sensor to logic “1.” When the slot disappears from the photo sensor’s axis, the logic output is reversed and returned to its original state, creating a momentary switch action. The two components of the OPB960N55 are connected to a common ground, allowing the emitter to draw current from the receiver. The two components are then wired to the circuit in a series connection. This ensures that if the transmitted signal is disrupted or blocked, the receiver will fail and the output of the sensor will remain in its original state.The OPB960N55 makes uses of the properties of a phototransistor as its principle of operation. A phototransistor is a kind of transistor that conducts current in response to light, with higher frequencies of light producing higher amounts of current. The OPB960N55 uses this property to differentiate between the presence and absence of the slot. The OPB960N55 is a cost-effective, low-power solution for a variety of industrial applications. Its fast response time and compact design make it suitable for a range of uses, from material handling to safety and security systems. Its low power consumption makes it an energy-efficient solution to a wide range of problems.
