OPB380T55Z

The OPB380T55Z Transistor Output Slot Type Photointerrupter is an optical sensor designed to detect the presence of an object based on its ability to break an infrared lightbeam. It can be used in a wide variety of applications for automated and robotic devices, including industrial and medical automation, security, lighting and control, and aeolian turbine generation.

A Photointerrupter such as the OPB380T55Z uses an infrared light emitting diode (LED) and a phototransistor to detect objects interrupting an infrared lightbeam. Using two terminals, one for each of the LED and transistor, it is able to detect the object’s presence in the slot through its ability to block the lightbeam. When a suitable object interrupts the emitted light path, the photointerrupter is designed to output a transistor signal on the opposite side from the LED, indicating the presence of the object. This output signal is used as an indicator within automated systems.

The OPB380T55Z works on the principle of detection of an infrared ray that passes through a physical gap. This can be thought of as a light tunnel that is formed between the light source and the adjacent detector. The emitted light is usually within the 940nm - 1100nm wavelength range and is typically modulated. When an object passes through the gap, it will disrupt the modulated infrared, by either partially or completely blocking the beam. The output then activates a transistor located at the opposite side of the detector, which can be used as a signal to indicate the presence of the object.

The OPB380T55Z is an ideal photointerrupter for applications that require reliable detection of objects in a variety of situations, from industrial to security, lighting and control, medical automation, and aeolian turbine generation. The sensor can detect objects that pass through the gap at speeds of up to 6m/s, making it a reliable choice for use in high-speed applications. It also features low power consumption (<20mW), and a long lifetime of up to 2 million operations. With its small size and low profile design, the OPB380T55Z makes an ideal choice for applications where space and power are constraints.

In conclusion, the OPB380T55Z Transistor Output Slot Type Photointerrupter is a reliable and cost effective solution for detecting objects passing through a physical gap. With its ability to detect objects at speeds of up to 6m/s, high reliability, low power consumption, and long life cycle, the OPB380T55Z is an ideal choice for a variety of applications, including industrial and medical automation, security, lighting and control, and aeolian turbine generation.
