Technical details and application highlights

Review the complete description, feature set, and specification details before sending your inquiry.

The O1D300 laser distance sensor is a compact and high-performance solution for non-contact distance and level measurement in industrial environments. Using advanced time-of-flight technology based on Photonic Mixer Device (PMD), the sensor accurately detects bulk materials and opaque liquids. Its small form factor combined with a long measuring range makes it ideal for applications where space is limited but precision is critical.

Key Features

The O1D300 offers reliable measurement performance with a visible red laser spot that simplifies alignment during installation. Its high excess gain ensures consistent detection even on surfaces with varying reflectivity. The sensor supports flexible configuration through integrated programming buttons and a 4-digit alphanumeric display, allowing users to easily set parameters and switching points. Its compact housing enables seamless integration into machinery and automation systems.

Application

This laser distance sensor is widely used for level monitoring in silos, storage containers, and industrial tanks. It is also suitable for detecting material height on conveyors, monitoring fill levels in bulk storage systems, and measuring positions in automated production lines. Its non-contact operation makes it especially effective in environments where direct contact is not possible or could lead to contamination or wear.

Design & Functionality

The O1D300 operates by emitting a focused laser beam toward a target surface and calculating the distance based on the time taken for the reflected signal to return. This time-of-flight principle ensures accurate and stable measurements over longer distances. The sensor’s compact dimensions allow installation in confined spaces while maintaining reliable performance.

Total Crossed Beams

The sensor uses a precise laser beam to ensure consistent detection across different material surfaces, improving measurement accuracy and reducing signal loss.

Beam Pitch Options

Optimized beam focus allows the sensor to detect targets effectively across its measuring range, ensuring reliable readings in various industrial setups.

Intrinsic Synchronism

The internal measurement process is synchronized to provide stable and repeatable output signals, supporting accurate automation control.

Operational Advantages

The O1D300 enhances industrial efficiency by providing continuous, real-time measurement data. Its non-contact operation eliminates mechanical wear and reduces maintenance requirements. The ability to install the sensor at a safe distance improves operational safety while maintaining measurement accuracy. With its robust design and IP67 protection, it performs reliably even in demanding environments, making it a dependable choice for modern automation systems.
