The Optex AX-70PN and AX-70TN photoelectric infrared detectors are versatile and reliable sensors designed for various automatic control applications. They are available in two versions the AX-70PN for detecting targets with a reflective surface, and the AX-70TN for detecting targets with an absorptive surface or in the dark.
The Optex AX-70TN photoelectric infrared detector features an infrared emitting diode and a phototransistor that forms a sensitive optical receiver. It emits an infrared beam that is reflected back when it encounters a target. This reflected infrared light falls on the phototransistor, causing a change in resistance and subsequently triggering an output signal.
This sensor offers a detection range of up to 30mm (1.2 inches) and a detection angle of up to 20 degrees. It is suitable for detecting targets as small as 6mm (0.24 inches) in diameter. The AX-70TN operates on a 5V DC power supply and features a rugged, compact design that makes it ideal for use in harsh environments. It is resistant to water splashes and can withstand temperatures ranging from -20 C to 70 C (-4 F to 158 F).
The Optex AX-70TN photoelectric infrared detector comes with adjustable sensitivity and timing features, allowing users to fine-tune the sensor to their specific application requirements. It also includes a built-in LED indicator that shows the sensor status, making troubleshooting and maintenance easier.
In summary, the Optex AX-70TN photoelectric infrared detector is a robust and versatile sensor designed for various automatic control applications, particularly in environments where targets have absorptive surfaces or are in the dark. It offers adjustable sensitivity and timing features, a wide detection angle, and a rugged design that can withstand harsh conditions.
The Optex AX-70PN and AX-70TN photoelectric infrared detectors are popular choices for automatic machinery and industrial automation due to their reliable sensing capabilities. Here are some pros and cons that can help you make an informed decision about purchasing one of these detectors.
Pros:1. High Sensitivity: The Optex AX-70PN and AX-70TN detectors have a high sensitivity, making them suitable for detecting objects in low-light conditions or at long distances.
2. Versatile Applications: These detectors can be used in various industries, including manufacturing, material handling, and automotive. They can detect objects of different sizes, shapes, and colors.
3. Durable Construction: The detectors have a robust and weather-resistant design, making them suitable for use in harsh environments. They can withstand high temperatures, humidity, and dust.
4. Adjustable Sensing Range: The detectors offer adjustable sensing ranges, allowing users to customize the sensing distance according to their specific application requirements.
5. Easy Installation: The detectors are easy to install and require minimal wiring, making them a cost-effective solution for automating processes.
Cons:1. Limited Detection Angle: The detectors have a limited detection angle, which may require multiple detectors to cover a larger area.
2. Sensitivity to Surrounding Conditions: The detectors can be affected by surrounding conditions such as temperature, humidity, and dust. This may require calibration to maintain accurate sensing.
3. Limited Communication Options: The detectors do not offer advanced communication options, such as Ethernet or Wi-Fi, which may limit their integration with advanced control systems.
In conclusion, the Optex AX-70PN and AX-70TN photoelectric infrared detectors offer high sensitivity, versatility, and durability, making them suitable for various industrial applications. However, they have some limitations, including a limited detection angle, sensitivity to surrounding conditions, and limited communication options.
Based on the pros and cons, if you require a reliable and cost-effective solution for sensing objects in a specific application with a limited detection range, then these detectors may be a good fit for you. However, if you require advanced communication options or a broader detection angle, then you may need to consider other detector types or brands. Ultimately, the decision to purchase the Optex AX-70PN or AX-70TN photoelectric infrared detector depends on your specific application requirements and budget.
