The GL3547-1 from SENBA’s Plug-in Series is a high-sensitivity photoresistor (LDR) designed for precise ambient light detection in electronic control and automation systems. With a peak spectral response at 540nm, it is optimized for visible light sensing applications such as automatic lighting control, brightness adjustment, and energy-saving solutions.
This device supports a maximum operating voltage of 100VDC and a power rating of 50mW, ensuring stable and reliable performance in a wide range of circuit designs. It features a resistance range of approximately 5kΩ to 50–100kΩ depending on light intensity, providing smooth and accurate analog response to changing ambient lighting conditions.
The GL3547-1 operates reliably across a wide temperature range of -30°C to +70°C, making it suitable for both indoor and outdoor environments. Its plug-in design allows for easy installation and direct integration into PCB-based systems, reducing assembly complexity and improving design flexibility.
Compared to fixed-output sensors, this LDR offers continuous resistance variation based on ambient light levels, making it a simple, cost-effective, and reliable solution for dynamic light sensing applications.
