SICK DT35-B15251 1057652 Laser Distance Sensor Dx35

SICK DT35-B15251 is a mid-range distance sensor from the Dx35 series based on HDDM+ technology. The red laser source (class 2, λ=658 nm) with a light spot of 15 mm×15 mm at 2 m provides precise, non‑contact distance measurements on natural objects even under adverse conditions. A high level of immunity to ambient light, flexible speed/range/repeatability settings and the compact housing make the sensor suitable for demanding automation tasks in factory automation, fill‑level monitoring and logistics.

Applications:

• Distance measurement in conveyor systems and automated storage

• Fill‑level monitoring of silos, bulk goods and tanks

• Positioning of stacked goods, pallets and mobile parts

• Collision monitoring on automated guided vehicles (AGV)

• Weight: approx. 65 g

System Integration:

• The sensor belongs to the SICK Dx35 series of mid‑range distance sensors.

• The 5‑pin M12 male connector (wiring diagram) supports connection to standard industrial control systems.

• Speed, range and repeatability can be flexibly adapted to the application via configurable parameters.

• IO‑Link V1.1 (process data, parameter setting and diagnostics, data retention) is available on the shared analog/digital line.

• Additional functions include teach‑in of the analog output with invertible function, switching of output Q2 between current/voltage/digital output, and switching modes for distance measurement: DtO (Distance to Object), switching window or object between sensor and background (ObSB).

Compatibility:

• Suitable for standard industrial controllers (PNP/NPN inputs) via the configurable push‑pull output.

• For parameter setting and diagnostics, an IO‑Link master and appropriate engineering software (e.g. SICK SOPAS) are required.
