SICK DL100-21AA2101 Sensor
SICK DL100-21AA2101 long-range laser distance sensor. Time-of-flight measurement for crane positioning, bulk level and long-travel detection tasks.
Overview
The SICK DL100-21AA2101 is a long-range laser distance sensor of the DL100 family. Using time-of-flight measurement, it determines the distance to the target precisely and almost independently of surface color, making it suitable for positioning and level tasks over extended distances on cranes, storage systems and material handling equipment.
How It Works
The sensor emits laser pulses and measures the time the light needs to travel to the target and back. From this time of flight it calculates the distance and provides it as a switching signal or analog/proportional output, depending on the variant configuration. Because evaluation is based on runtime rather than reflected brightness, dark targets are measured as reliably as bright ones.
Key Features
- Time-of-flight laser measurement over long distances
- Distance reading largely independent of target color and surface
- Precise, visible laser spot for straightforward alignment
- Rugged housing for crane ways, warehouses and outdoor-adjacent areas
- Switching and measuring output options within the family
- Red laser light source for a clearly visible measurement spot
Typical Applications
- Position detection of cranes and transfer cars on long travels
- Stacker and storage and retrieval system positioning
- Level monitoring of bulk material in large containers
- Distance measurement to moving vehicles on logistics lines
- Door and barrier position monitoring at long range

Installation and Setup Notes
Mount the sensor rigidly, since any vibration translates directly into measurement scatter at long distances. Aim the laser spot at a flat section of the target and avoid grazing angles that deflect the reflection. After installation, verify the reading against a reference distance and allow for a small blind zone in front of the optical face.
Frequently Asked Questions
Can the DL100 measure black rubber surfaces?
Yes. Time-of-flight evaluation depends on runtime, not reflected intensity, so dark targets are measured at the same distance rating as bright ones.
Does it provide a continuous distance value?
The DL100 family is designed for distance measurement and provides the distance as a proportional output in addition to switching functions, depending on the variant.
What maintenance does it need?
Essentially only periodic cleaning of the optical window in dusty environments.
