Optical Sensors - Photointerrupters - Slot Type - Transistor Output comprises of devices such as the OPB870P55. The OPB870P55 is an optically-isolated device which provides high-precision, linear sensing of a free-moving object. It uses an infrared light beam to detect the object. It has a very fast response time and is extremely reliable.

The OPB870P55 is typically used in industrial process automation applications such as position sensing, gap detection, conveyor belt tracking, and other similar tasks. It is also used in other applications where detection of a moving object is required, such as robotics and medical equipment.

The device comprises of an infrared emitting diode (LED) and a detector in the form of a phototransistor. The device is configured with the LED and phototransistor facing each other. A narrow slit is cut in a block of plastic which creates a dark space between the two components. When an object passes through the gap, the infrared light emitted from the LED is blocked, and the transistor switches off. When the object passed, the transistor switches back on. The transistor output is a voltage-based signal whose magnitude is proportional to the light strength.

The OPB870P55 is a very small, self-contained device with minimal external components. It has a detection range of up to 3.4 mm, and its response time is as fast as 32 microseconds. It is very easy to integrate into any existing system due to its simple wiring scheme. Its mounting hole accepts a wide variety of conventional machine screws.

The OPB870P55 is an extremely reliable device which can withstand harsh environmental conditions such as vibration, shock, dust, and moisture. It is rated for up to one million operations, making it ideal for long-term applications. It is also highly resistant to electrical noise and requires no polarity.

The OPB870P55 offers a high level of accuracy, excellent stability, and wide temperature range. It is also very easy to install and does not require any special adjustment or calibration. It is also very economical and requires minimal power, making it ideal for battery-operated applications. It is also suitable for a variety of industries, including automotive, aerospace, industrial, and medical.

In summary, the OPB870P55 application field is extremely broad and can be used in many different industries. It is highly reliable, easy to install, and requires minimal power. It offers accurate readings and has a fast response time, making it ideal for industrial and robotic applications.
