Distance linear image sensor S15452-01WT - 1

Distance linear image sensor S15452-01WT NIR-enhanced type, measures the distance to an object by TOF method The distance image sensor is designed to measure the distance to an object by TOF (time-of-ﬂight) method. When used in combination with a pulse modulated light source, this sensor outputs phase diﬀerence information on the timing that the light is emitted and received. Distance data can be obtained by performing calculation on the output signal with an external signal processing circuit or on a PC. We provide an evaluation kit for this product. Contact us for detailed information. High sensitivity in the near infrared region Obstacle detection (self-driving, robots, etc.) Improved tolerance to background light Security (intrusion detection, etc.) Compact wafer level package (WLP) type Shape recognition (logistics, robots, etc.) Motion capture Touchless operation Structure Parameter Image size Pixel pitch Pixel height Number of pixels Number of eﬀective pixels Package Note: This product is not hermetically sealed.

Dew condensation on the product may cause deterioration in characteristics and reliability. *2: Reﬂow soldering, IPC/JEDEC J-STD-020 MSL 2, see P.9 Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.
