Industrial Applications

1. Material Handling and Conveyor Systems

Precisely detect the presence or absence of packages, boxes, or components on a conveyor belt, ensuring proper spacing and preventing jams. The through-beam principle ensures reliable detection even for objects with varying colors or reflective surfaces, leveraging its 0-800mm sensing range and 100 Hz switching frequency.

Problem Solved

Prevents material pile-ups and ensures smooth flow in automated material handling, eliminating errors caused by optical sensor limitations with certain material types in dynamic industrial environments.

2. Level Control in Opaque Tanks

Monitor the high or low fill level of granular materials or liquids in small to medium-sized opaque tanks or hoppers where direct contact with the medium is undesirable. The miniature design allows for easy integration, and the 0-800mm range facilitates precise point level detection.

Problem Solved

Provides reliable level indication without needing to immerse the sensor, suitable for corrosive, sticky, or sensitive materials in harsh conditions, using its robust IP67 rating and ultrasonic capabilities.

3. Door and Gate Position Monitoring in Harsh Environments

Accurately detect the open or closed position of industrial doors, safety gates, or movable machinery parts in environments subjected to dust, dirt, or moisture. The IP67 rating ensures reliable operation in challenging conditions, and the through-beam principle provides dependable presence detection.

Problem Solved

Offers robust and consistent position feedback where traditional optical sensors might fail due to environmental contamination, ensuring safety interlocks and automated processes function correctly thanks to its IP67 protection and wide operating temperature range (-25°C to 70°C).
