Distance area image sensor S15454-01WT - 1

Distance area image sensor S15454-01WT 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.) Number of effective pixels: 96 (H) × 72 (V) Shape recognition (logistics, robots, etc.) Compact chip size package (CSP) type Motion capture Touchless operation Structure Parameter Image size Pixel size Pixel pitch 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.10 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 rating
