Optical Sensors - Photointerrupters - Slot Type - Logic Output

The OPB991T51 is an optical slot sensor with a logic output. It is a plastic mold type photointerrupter that is designed for use in automated equipment in a wide variety of application fields. With its high optical sensitivity and wide signal range, it can be used in industry, consumer goods and consumer electronics.

The OPB991T51 has a wide viewing angle of up to 30 degrees and an extremely narrow slot width of 0.2 mm. This makes it ideal for detecting small, fast-moving objects such as PCBs or sheet metal parts. The sensor is designed to be used in harsh environments thanks to its robust plastic construction and large operating temperature range of -40 degrees C to +100 degrees C.

The OPB991T51 works on a principle of optical signal detection. When an object passes through the slot, its shadow is detected by the sensor, which then sends a logic signal to the output port. The logic output can be used to detect the presence of the object, its direction of travel and its speed. This makes it perfect for a wide range of applications such as pick and place systems, assembly lines and process automation.

The sensor is easy to install and requires no additional power source. Only a power supply is needed to power the output circuit, giving it an efficient, low-cost operation. Additionally, it has an integrated LED light source with an output power of 50 mW and an active operating range of up to 600 m.

The OPB991T51 can be used in a wide range of applications due to its high optical sensitivity, wide signal range, and wide viewing angle. These include factory automation, consumer electronics, automotive, and medical equipment. It is also perfect for use in harsh environments, offering a robust construction and an operating temperature range of -40 degrees C to +100 degrees C.

Overall, the OPB991T51 is a versatile optical slot sensor capable of detecting small, fast-moving objects. Its high optical sensitivity, wide signal range, and wide viewing angle make it perfect for a wide range of applications. Thanks to its robust construction and large operating temperature range, it can be used in harsh environments, making it an ideal choice for a wide range of industries.
