The RS412/RL412/RM412 Programmable Digital Series PIR motion sensors from SENBA are high-performance passive infrared sensing devices designed for accurate and flexible indoor motion detection. Featuring digital signal output with programmable register configuration, this series allows designers to customize key parameters such as sensitivity, delay timing, and detection behavior, enabling optimized performance for specific applications.
Operating within a wide voltage range of 1.6V to 5.5V, these sensors are suitable for both low-power and standard electronic systems. With ultra-low static current consumption of less than 12µA, the RS412/RL412/RM412 series is ideal for battery-powered and energy-efficient designs. Built-in temperature compensation ensures consistent detection performance across varying environmental conditions, improving reliability and reducing false triggering.
The sensors offer a sensing distance of up to 10 meters when used with an S9008-2 23mm lens, along with wide detection angles of 120°, 125°, and up to 130° for effective indoor coverage. Multiple window size options (4×3mm / 5×3.8mm / 5.2×4.2mm) provide flexibility for different product designs.
Compared to standard PIR sensors, this programmable series delivers enhanced adaptability, stable operation, and precise motion detection, making it ideal for modern indoor smart sensing applications.
