The PYQ 1048 is an optical motion sensor for applications requiring an accurate measurement of the speed of a target object. It utilizes an undersized lens integrated with a imaging chip for its sensing ability. With its precision and rapid response, it is also suitably utilized for positional control and guidance in many industrial applications.

The PYQ 1048 motion sensor works by using the optical principle of Doppler shift. A tiny lens mounted in front of the detector and facing the target object is employed as the sensing element. When a target object moves across the sensor\'s field of view, a Doppler shift is produced in the frequency of the light waves the object emits. The lens is used to focus the light waves, which in turn creates a directional image on the imaging chip in the PYQ 1048.

The optical motion sensor detects the direction of the movement by calculating the phase difference between each of the pairs of light wave sets. Since the change in frequency is proportional to the speed of the target object, this allows the sensor to measure the speed as well as the direction of the object. It is important to note that the PYQ 1048 motion sensor is not sensitive to objects of the same color as the background, as it relies only on reflective properties for target detection.

The PYQ 1048 motion sensor can measure the speed of a target object up to 4m/s and accurately and reliably determine the direction of the target. The output response rate is approximately 5-20Hz, depending on the speed of the target. It is also designed to be accurate within +/-3 degrees in relation to the direction of the object. The sensor is available in several versions, allowing users to choose the type of output they need, whether it be Pulse Width Modulation (PWM), frequency square wave, or linear analog output.

The PYQ 1048 motion sensor offers a highly accurate and reliable way to measure the speed and direction of moving objects. Its robust design and reliable performance make it suitable for use in a variety of motion sensing applications such as speed and angle measurements, tracking, robotic guidance, etc. The flexibility of the PYQ 1048 makes it an ideal choice for those who require high accuracy and fast response when measuring motion within their equipment.
