What the SICK DL100-23AB2109 Delivers in Long-Range Position Feedback

The SICK DL100-23AB2109 is a phase-shift optical time-of-flight laser distance sensor in the Dx100 series. It measures 0.15 m to 300 m on Diamond Grade reflective tape and reports over a CANopen fieldbus interface. For oil and gas engineers, this combination of range and fieldbus output removes the need for mechanical encoders on long linear travel.

This unit is built for demanding environments. Its die-cast aluminum housing, IP65 rating, and -20 °C to +55 °C operating window suit outdoor yards, tank farms, and unheated process buildings. The sensor is mission-critical where position feedback drives automated storage, crane travel, or gate positioning.

This unit also provides continuous condition monitoring of signal level attenuation, laser diode aging, and temperature tracking. This data supports predictive maintenance without extra instruments.

How to Evaluate This unit for Your Application

Start with range and target. The 300 m capability depends on Diamond Grade reflective tape. If your installation cannot use this tape, the effective range will be shorter. Confirm the tape specification before committing to a layout.

Next, check the interface. This unit uses CANopen (CiA DS 301, DS 406 profile). Your controller or network master must support this protocol. Two push-pull digital outputs and a multifunctional input are also available for auxiliary signaling.

Then review the electrical envelope. The DC 18 V to 30 V supply range and 8 W to 10 W consumption must fit your panel capacity. Reverse-polarity protection helps during commissioning, but correct polarity remains essential.

Finally, match the environment. The -20 °C to +55 °C operating temperature and IP65 rating cover many outdoor and washdown-adjacent areas. For extreme cold or high-pressure cleaning, verify the limits against your site conditions.

Integration and Installation Notes

This unit connects through M12 connectors. Power uses a 4-pin male connector; CANopen uses two 5-pin A-coded SPEEDCON™ connectors for in/out daisy-chaining. This arrangement simplifies wiring in cabinets and on moving structures.

An integrated LC display with menu navigation supports setup and diagnostics. The optical 3-axis alignment bracket compatibility helps align the laser path over long distances. Because the laser is Class 2, avoid direct eye exposure and follow the safety manual.

When wiring into a CANopen network, confirm termination and cable routing with the supplier. This unit is a fieldbus device; integration may require a gateway or connection module depending on your control architecture. Contact PetroPartsOnline for parts suited to your application's requirements.

Reliability and Maintenance in Oil and Gas Duty

This unit is field-proven in automated storage and retrieval systems, where 15 m/s tracking velocity and 15 m/s² acceleration are routine. In oil and gas settings, the same dynamics apply to crane travel, gate positioning, and long conveyor lines.

Condition monitoring flags signal attenuation, laser diode aging, and temperature drift. Schedule periodic inspection of the PMMA optical window and the M12 connectors. In dusty or humid areas, confirm the IP65 seal remains intact. These checks support reliability you can depend on.
