Optical sensors are devices that convert photons into some form of electrical output, such as a voltage, current, or frequency. Photo detectors are a type of optical sensor that detect incident light. Logic output photo detectors are photo detectors with logic outputs, which allow them to detect more complex incident light patterns. The OPL535B is an example of a logic output photo detector.

Features of the OPL535B

The OPL535B is a logic output photo detector from Avago Technologies. It features a number of unique characteristics, including:

• Non-contacting ASK receiver with a 10mm sensing range
• A low operating voltage of 1.8Volts
• A minimum supply voltage of 1.2V and a maximum supply voltage of 5.5V
• A high frequency response (up to 1MHz)
• A low power consumption of up to 4mA

Applications of the OPL535B

The OPL535B can be used in a wide variety of applications, including:

• Access control systems, such as electric locks
• Home automation systems, such as door and window sensors
• Security alarm systems, such as motion detectors
• Robotics and industrial automation

Working Principle of the OPL535B

The OPL535B is an ASK (amplitude-shift keying) receiver, which means it reads signal data encoded in binary format, where two different states of voltage represent the two binary values (0 or 1). The OPL535B has three optical/halide lenses: an infrared emitter (IRED), an integrated photo detector die (LSI) and a logic output. The IRED emits a continuous current of infrared light, which is received by the photo detector die. The photo detector then converts the received light into an electrical current, which is then sent to the logic output as a binary value.

The OPL535B has a receiver sensitivity range of 10mm, which means it can detect infrared light from up to 10mm away. It also has a response time of typically 15 milliseconds, which means it can detect and respond to changes in the environment quickly and accurately.

Conclusion

The OPL535B is a logic output photo detector from Avago Technologies. It can be used in a wide variety of applications, including access control systems, home automation systems, security alarm systems, and robotics and industrial automation. The OPL535B features a low operating voltage, high frequency response, and low power consumption, making it an ideal choice for many applications. The OPL535B works by receiving infrared light from up to 10mm away and then converting that light into an electrical current, which is then sent to the logic output as a binary value.
