S18-L462B-3 2.2–3.7V PIR Motion Sensor Digital Output | Quad Adjustable Delay Sensitivity Light Control 3–5M 80° | SENBA
SENBA
The S18-L462B-3 from SENBA’s SMD-PCB Series is a feature-rich, low-power PIR motion sensor engineered for accurate short-range human motion detection in compact electronic designs. With high and low level digital output, combined with adjustable delay, sensitivity, and ambient light control, this sensor provides advanced flexibility for fine-tuned motion sensing performance. Its quad element structure enhances detection precision and significantly reduces false triggering caused by environmental disturbances.
Operating within a low voltage range of 2.2V to 3.7V, the S18-L462B-3 is optimized for battery-powered and portable applications. With ultra-low static current consumption of just 9.5µA, it ensures long operational life and efficient power usage. The sensor supports a detection range of 3 to 5 meters when used with an SB-F-11 lens, making it ideal for close-range applications.
The focused 80° induction angle enables precise detection within a defined area, minimizing unwanted triggers. Its large 6.6×6.6mm window enhances infrared signal reception, improving sensitivity and stability. Adjustable sensitivity allows detection range customization, while built-in light control supports day/night functionality for energy-efficient operation.
Compared to standard PIR sensors, the S18-L462B-3 delivers superior control, enhanced accuracy, and improved reliability, making it a strong choice for compact PCB-based smart sensing applications.
