The Keyence PQ-01 Thrubeam Sensor is a compact, high-precision detection device designed for applications that require short-range but highly accurate object detection. With a detecting distance of 100 mm (3.94 inches), it provides stable performance in close-range setups, making it particularly well-suited for applications such as fine part inspection, positioning, and presence/absence detection in automated systems.

A standout feature of the PQ-01 is its ability to detect extremely small objects, down to 0.5 mm (0.02 inches) in diameter, such as thin copper wire. This level of sensitivity makes it highly effective for industries requiring fine-scale detection, including electronics, precision manufacturing, and component assembly. It ensures even the smallest parts are consistently identified, reducing the risk of production errors and improving overall quality assurance.

The PQ-01 uses a thrubeam design, which consists of an emitter and receiver placed opposite each other. This setup provides highly accurate detection because the sensor only triggers when an object interrupts the beam. With a short detecting distance of 100 mm, the PQ-01 is optimised for precision, ensuring stable operation even when dealing with minute targets in confined spaces.

Equipped with an infrared LED light source, the PQ-01 ensures consistent beam quality and energy efficiency. Infrared light offers reliable performance in environments where visible light interference may otherwise affect detection accuracy. This makes the sensor dependable in a wide variety of operating conditions, from controlled laboratory setups to factory production lines.

Another key advantage of the PQ-01 is its fast response time of 1 ms maximum. This rapid reaction speed ensures that high-speed production lines and automated processes maintain accurate detection without delay. By combining high sensitivity with quick responsiveness, the PQ-01 supports the efficiency and throughput requirements of modern manufacturing systems.

Durability and reliability are central to the PQ-01’s design. Built with the robust quality expected of Keyence products, it withstands the rigours of industrial use while continuing to deliver consistent performance. Its compact construction makes it easy to install, even in tight spaces or complex machinery, providing engineers with flexibility in system design.

In summary, the Keyence PQ-01 Thrubeam Sensor is a precision detection solution that offers short-range, high-accuracy performance. With a 100 mm detecting distance, the ability to detect objects as small as 0.5 mm, an infrared LED light source, and a rapid 1 ms response time, it is tailored for applications demanding both sensitivity and speed. For industries where precision and reliability are critical, the PQ-01 is a powerful and practical choice.
