OPB920DZ

Optical sensors are sensors which use electromagnetic radiation in the visible region of the spectrum to detect and measure physical parameters. Photointerrupters are one type of optical sensor which are commonly used for sensoring and detection in industrial applications. They are typically used to sense the presence of an object, measure its size or count the number of objects passing a certain point. The OPB920DZ is a slot type photointerrupter with a transistor output.

The OPB920DZ photointerrupter uses the slot type sensing technology to detect presence or absence. This type of photointerrupter works by the light interruption method. It uses an LED on one side and a photosensitive transistor on the other side of a streak filled slot. When an object passes through the slot, the LED light is blocked, resulting in the transistor output changing state. This output state is then used for further processing by the circuit.

The OPB920DZ is designed to be highly reliable and to provide superior performance in a wide range of applications. It is suitable for industrial applications in which precise detection is important, such as in sealing or packing machines, door switches, and product counting. Its wide operating voltage and temperature range from -20°C to + 80°C, make it highly suitable for a variety of industrial applications. In addition, its strong protection against electrostatic interference and wide detection range make it extremely stable and reliable.

The OPB920DZ is designed to be very easy to install. It requires only minimal wiring and is designed to be compatible with a variety of mounting systems. Its small size and low power consumption make it suitable for applications in which space is a premium or in which energy savings are a primary concern.

The working principle of the OPB920DZ is based on the interruption of light due to the passing of an object through the optical slot. The interrupted light causes a decrease in the output of the photosensitive transistor. This change in output is then processed and sent as an output signal by the circuit. This output can then be used to trigger further actions in the circuit, such as switching on or off, opening or closing relays, and triggering alarms.

The OPB920DZ is a highly reliable and robust optical sensor with an excellent performance even under the most challenging conditions. It is suitable for a wide range of industrial applications in which precise detection of objects is required, such as door switches, product counting, sealing or packing machines, and much more. Its small size and low power consumption make it an attractive choice for applications in which energy savings and space considerations are important.
