Long-Range Laser Positioning for Demanding Environments

The SICK DL100-23HA2112 is a phase-shift optical time-of-flight laser distance sensor designed for precise, long-range measurement in rugged industrial settings. With a measuring range of 0.15 m to 300 m on Diamond Grade reflective tape, it delivers dependable performance for mission-critical positioning tasks.

Over the years, oil and gas operations have evolved from manual gauging to automated, data-driven processes. The DL100-23HA2112 reflects that shift, combining a visible red laser diode (658 nm, Class 2) with PROFINET IO connectivity to provide real-time distance feedback in harsh environments.

The integrated heating system ensures reliable operation in cold-storage facilities down to -40 °C, while the rugged aluminum housing withstands the demands of outdoor and washdown environments.

Applications in Oil and Gas

In oil and gas operations, accurate distance measurement is critical for inventory management, crane positioning, and safety systems. This unit excels in these areas due to its long range and high tracking velocity of up to 15 m/s. For example, automated storage and retrieval systems (ASRS) benefit from the sensor's ability to track fast-moving targets with acceleration up to 15 m/s².

Additionally, the IP65 rating and wide temperature range make it suitable for outdoor installations, from scorching deserts to freezing arctic conditions. The PROFINET IO interface allows seamless integration into modern control systems, enabling real-time data acquisition for process optimization.

Installation and Setup

Installing This unit is straightforward thanks to its M12 connectors and optical 3-axis alignment bracket compatibility. The power connection uses a male M12 4-pin connector, while PROFINET communication uses two female M12 4-pin D-coded connectors with SPEEDCON™ technology for quick and secure connections.

For optimal performance, ensure the reflective tape is clean and properly aligned. The integrated LC display with intuitive menu navigation simplifies configuration and diagnostics. Always follow the manufacturer's safety manual for laser class 2 products.

Maintenance and Reliability

This unit is built for demanding environments, with a robust aluminum die-cast housing and PMMA optical window that resist dust and water ingress. Periodic inspection of the optical window and connectors is recommended to maintain measurement accuracy. In cold conditions, the internal heating system activates automatically to prevent condensation and ensure reliable operation.

With no moving parts, the sensor offers long-term reliability and minimal maintenance, reducing downtime and total cost of ownership.
