The GL3537-1 from SENBA’s Plug-in Series is a high-sensitivity photoresistor (LDR) designed for accurate ambient light detection in electronic control systems. With a peak spectral response at 540nm, this device is optimized for visible light sensing applications such as automatic lighting control, brightness regulation, and energy-efficient system design.
Rated for a maximum operating voltage of 100VDC and 50mW power dissipation, the GL3537-1 ensures stable and reliable performance across a wide range of electronic circuits. It features a resistance range of approximately 2kΩ to 20–30kΩ depending on light intensity, enabling smooth and responsive analog light-to-resistance conversion.
The device operates reliably in 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 effort and improving design flexibility.
Compared to fixed-output light sensors, the GL3537-1 provides continuous resistance variation based on ambient light levels, offering a simple and cost-effective solution for dynamic light sensing applications.
