Optical sensors are one of the most widely used sensing technologies in modern automation and robotics. Photointerrupters, which specialize in sensing the interruption of light, are a common type of optical sensor. The OPB916BZ, a slot type photointerrupter with logic output, is one of the many available photointerrupters.

The OPB916BZ has a wide range of applications, including optical switching, home and office automation, security systems, safety mechanisms, and numerous other machine control systems. Its operating range is between 4.5 to 36VDC, and its logic output changes between high and low, or “0” and “1”. This makes it particularly effective for applications that require instantaneous input of binary data.

The OPB916BZ operates in the transmission of infrared light from an integrated infrared emitter to a phototransistor detector located just above the emitter. A slit in the centre of the device\'s housing separates the two, so that when an object interrupts the light path, the phototransistor\'s current is cut off and the logic output changes state. It\'s extremely fast response time, which is less than 100us, makes it especially suitable for applications which require prompt reaction to changes in the environment.

Its construction includes a thermally separated terminal block, a rugged polycarbonate housing and a display lens. This makes it resistant to moisture,corrosion, shock and wear, and allows for a wide operating temperature range of -25˚C to 80˚C. It also has a wide operating current of 1mA to 120mA, and a high-sensitivity input current of 0.2mA to 1mA. With its flexible operating range and durable construction, the OPB916BZ has become an extremely popular choice in optical sensing.
