The GL11516 with Photoresistors ThroughHole RoHS manufactured by Jing Chuang is a electronic part that serves as a light-sensitive resistor. It is designed with an aluminum oxide substrate to enhance its photoresistive properties. The device can detect changes in light levels from visible light frequency such as red, yellow, blue, green, and infrared. It has a high speed response time, and a good tolerance to temperature and humidity. The resistance of the device changes in proportion to the amount of light exposure, which allows it to be used for applications such as lightactuated switches, reverse current protection mechanisms, panels, and auto-level lighting systems. The device is RoHS compliant and can be used in harsh environments.
