Product Introduction
I. UK SST Photoelectric Liquid Level Sensor / Photoelectric Liquid Level SwitchLLC200D3LSH(Industrial Grade) Product Description：
Level SensorsProvides single-point liquid level detection with TTL-compatible push-pull output. The sensor is designed with an infrared emitter and a detector, precisely positioned to ensure good optical coupling in air. When the conical end of the sensor is immersed in liquid, the infrared light is transmitted out of the conical surface, and the light intensity reaching the detector weakens.
The LLC seriesphotoelectric liquid level sensors(industrial grade, photoelectric water immersion sensors) are designed for industrial applications. They can handle heavy-duty environments in industrial applications. This series is suitable for wide voltage range power supply and can drive up to 250mA. Therefore, this series of sensors can directly drive alarms and other devices.
