The S22-P340R/S22-P341R from SENBA’s SMD-Plastic Sealing Series are high-performance PIR motion sensors designed for precise short-range human motion detection in compact and sealed electronic applications. Featuring high and low level digital output along with adjustable delay, sensitivity, and ambient light control, this series provides full flexibility for optimized motion sensing performance. The integrated quad element structure enhances detection accuracy and minimizes false triggering caused by environmental interference.
Operating within a low voltage range of 2.2V to 3.7V, these sensors are ideal for battery-powered and portable devices, delivering ultra-low static current consumption of just 9.5µA for extended operational life. With a sensing distance of 3 to 5 meters when paired with an SB-F-11 lens, they are well-suited for close-range detection applications.
The focused 80° induction angle ensures precise detection within a defined area, reducing unwanted triggers. A large 6.6×6.6mm window improves infrared signal reception, enhancing sensitivity and stability. Adjustable sensitivity allows fine-tuning of detection range, while built-in light control supports efficient day/night operation.
Compared to standard PIR sensors, this plastic-sealed series offers improved durability, enhanced environmental protection, and superior detection control, making it ideal for compact, robust sensing solutions.
