SICK DT35-B15251 Sensor
SICK DT35-B15251 laser distance sensor, part 1057652. Precise mid-range distance measurement for winding diameter, level and positioning tasks.
Overview
The SICK DT35-B15251 (part number 1057652) is a photoelectric distance sensor of the DT35 family. It measures distance precisely with visible red laser light and provides switching and measurement signals for positioning, level and diameter monitoring tasks in packaging, processing and material handling.
How It Works
The sensor emits modulated laser light and evaluates the returned signal to determine the distance to the target. Because evaluation is distance-based, target color and brightness have little influence on the reading. The visible laser spot shows exactly where the measurement is taken.
Key Features
- Precise laser distance measurement in the mid-range class
- Visible red laser spot for simple alignment
- Distance evaluation largely independent of target color
- Suitable for switching and continuous distance monitoring
- Part number 1057652
- Compact housing with robust optical window
Typical Applications
- Winding diameter monitoring on reels and rolls
- Position detection on conveyor transfer stations
- Fill and level checks in production containers
- Loop control on web processing machines
- Two-point distance monitoring on assembly equipment

Installation and Setup Notes
Mount the sensor perpendicular to the target where possible and protect the optical face from spatter and dust. Set the switching points with the real target at the real distances and verify the analog or proportional reading against a reference. At grazing angles to shiny surfaces, slightly tilt the sensor to return a stable signal.
Frequently Asked Questions
Can the DT35 measure winding diameter?
Yes, roll and winding diameter monitoring is one of the classic applications for this family.
Does the laser spot endanger operators?
The laser is classified for industrial operation; normal practice is to avoid staring into the beam.
What distinguishes B15251 from B15551?
They are neighboring variants of the DT35 family with different range and output configurations.
