Optical sensors are becoming an increasingly important part of modern electrical and electronic systems, many of which now rely on photointerrupters to detect and register the presence or absence of an object. The HOA1874-013 is a photointerrupter of the slot type, with a transistor output, which offers a highly reliable method of working with these systems.

Description

The HOA1874-013 is an optically operated device in a TO-5 package. This 4-pin package incorporates a GaAs LED, a phototransistor and a photodiode, together with the necessary optoelectronic components. It provides an ideal and highly reliable solution for optical sensing applications.

Applications

The HOA1874-013 can be used in a wide range of optical sensing applications, such as:

• Controls for current loops
• Presence detection
• Position sensing
• Level sensing
• Motion sensing
• Speed sensing

Operation

The HOA1874-013 photointerrupter works by generating a signal when the light from the LED is interrupted by an opaque object placed in the slot. The light is received by the integrated photodiode, which generates a current. The transistor then amplifies the current, which is then used to control the system.

The device can operate under a variety of conditions, including a variety of temperatures and light levels. With a wide variety of control options available, the device can be easily adapted to suit the application.

Advantages

The HOA1874-013 provides a number of advantages over traditional photointerrupters. These include:

• High reliability
• Excellent quality light output
• Flexible control options
• Wide operating temperature range
• Low power consumption

Conclusion

The HOA1874-013 is an ideal solution for applications requiring reliable optical sensing. It is well suited for applications where accuracy and precision are required, such as level sensing, motion sensing and speed sensing. The device is cost effective, reliable and easy to use, making it an attractive choice for many applications.
