Product description

The Milesight EM400-TLD is an advanced distance sensor based on Time of Flight (ToF) technology, specifically designed to detect fill level and position status in containers. Thanks to its 27° field of view (FOV), it eliminates almost all blind spots, making it perfect for small trash or storage containers.

This device not only measures distances; it integrates an NTC temperature sensor that alerts about possible fires inside the container and a 3-axis accelerometer to monitor whether the lid is open or if the container has been overturned. Its robust design with IP67 certification and internal moisture-proof coating guarantees flawless performance in critical outdoor applications and demanding industrial environments.
