How Do You Maintain Reliable Position Feedback in Freezers and Automated Storage Systems?

Cold-storage and automated storage and retrieval systems demand position feedback that survives condensation, ice and constant motion. The SICK DL100-22HA2110 answers that challenge with a phase shift optical time-of-flight measurement principle, a 0.15 m to 200 m measuring range on Diamond Grade reflective tape and an integrated heating system rated for operation down to -40 °C. This rugged sensor is part of the Dx100 DL100 Pro family and carries part number 1066431.

Key Features and Technical Specifications of the DL100-22HA2110

• Output time: Measurement cycle of at least 1 ms, with a continuous internal measurement rate of 1 ms; fieldbus cycle dependent.
• Communication: EtherNet/IP with dual-port 100 Mbit/s and DLR support, plus two push-pull digital outputs (PNP/NPN, configurable B/Q, ≤ 100 mA) and a multifunctional input.
• Supply voltage: DC 18 V ... 30 V with reverse-polarity protection.
• Power consumption: Typically 25 W ... 35 W with the internal heating element active.
• Operating temperature: -40 °C ... +55 °C with the integrated heating system active; storage range -40 °C ... +75 °C.
• Enclosure: IP65 per EN 60529 in an aluminum die-cast housing with acrylic glass (PMMA) optical window.
• Dimensions and weight: 69.4 mm x 82.5 mm x 100.2 mm, approximately 1,000 g.

The integrated heating system is the standout specification for cold-chain duty. Because it keeps the optical window clear at temperatures down to -40 °C, This unit delivers dependable distance readings where standard sensors frost over. The resulting power draw of 25 W ... 35 W must be planned into the cabinet supply, yet the DC 18 V ... 30 V input range leaves headroom for voltage drop across long cable runs.

Where This unit Fits in Oil, Gas and Storage Operations

Automated storage and retrieval systems benefit most directly from the 15 m/s tracking velocity and 15 m/s² acceleration. Consequently, the sensor keeps pace with high-speed stacker cranes without losing position lock. In cold-storage facilities, the internal heating system extends operation into freezer aisles where condensation would otherwise interrupt measurement.

Oil and gas yards also use long-range laser positioning for gantry cranes and pipe-handling equipment. The IP65 enclosure and aluminum die-cast housing resist dust and washdown spray in these demanding environments. Meanwhile, the Class 2 laser rating keeps the beam safe under normal operating conditions per IEC 60825-1:2014.

For engineers evaluating a proximity probe alternative, This unit offers a non-contact optical method with millimeter-level repeatability. It is not a drop-in substitute for every inductive or eddy-current probe, so review the measuring range and target material before selection.

Integration, Wiring and EtherNet/IP Connectivity

This unit connects through a male M12 4-pin power connector and two female M12 4-pin Ethernet connectors (D-coded, SPEEDCON™). Because the EtherNet/IP interface supports dual-port 100 Mbit/s and DLR, the sensor can sit on a ring topology for continued communication if one segment fails.

Integration note: wiring the sensor into an EtherNet/IP network may require an external gateway or connection module depending on your control architecture. Confirm cables and gateways with the supplier before commissioning. The integrated LC display and menu navigation simplify addressing and parameter review on the bench. In addition, the optical 3-axis alignment bracket compatibility helps technicians square the beam to the reflective tape.

Reliability and Maintenance in Demanding Environments

Field-proven reliability starts with the housing. The aluminum die-cast body and PMMA optical window resist impact and chemical exposure common in industrial yards. Periodic inspection of the optical window is advisable, particularly in freezer aisles where ice can accumulate. Cleaning should follow the manufacturer's instructions to avoid scratching the PMMA surface.

Check the M12 connectors for moisture ingress during scheduled shutdowns. Also verify that supply voltage remains within DC 18 V ... 30 V under load, since the heating element can draw up to 35 W. These simple checks support the reliability you can depend on from a mission-critical position sensor.
