Features:

  • Measures 0.2–35 m on Diamond Grade reflective tape.
  • Provides 100 µm resolution with selectable response profiles.
  • Combines IO-Link with configurable digital and analog outputs.
SICK DL35-B15552 calculates distance from the travel time of laser light returned by the reflector.

The chosen response profile links update speed, repeatability, and switching frequency rather than treating them as independent settings.

Teach functions assign the measured path to output thresholds without changing the sensor's exact optical configuration.

The SICK DL35-B15552 Time-of-flight Distance Sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Reflector-based measurement

  • Laser path: The red Class 1 beam travels to Diamond Grade reflective tape.
  • Return signal: The receiver measures the reflected light travel time.
  • Distance conversion: Internal processing converts flight time into a distance value.
  • Alignment: The optical axis must remain on the reflector over the full movement.

Selectable response profiles

  • Fast mode: The shortest response supports the highest switching frequency.
  • Intermediate modes: Several timing steps trade speed for measurement stability.
  • Slow mode: The 96.5 ms setting uses the lowest switching frequency.
  • Linked settings: Response time and switching frequency change as a coordinated pair.

Digital and analog channels

  • Q1: The first channel supplies a configurable digital switching result.
  • Q2: The second channel can be current, voltage, or digital.
  • IO-Link: The communication path carries process data and parameters.
  • Multifunction input: External teach or laser control is assigned by configuration.

Commissioning sequence

  • Mechanical position: Secure the two M4 mounting points before optical alignment.
  • Reflector alignment: Centre the beam on the installed reflective tape.
  • Teach values: Store the required switching or analog endpoints.
  • Verification: Move through the working range and confirm the outputs and IO-Link value.
Description
SICK DL35-B15552 is a Dx35 time-of-flight distance sensor for measurements from 200 mm to 35 m on Diamond Grade reflective tape. Its red Class 1 laser sends a beam to the reflector, and the returned flight time is converted into distance data.

The signal path in SICK DL35-B15552 supplies a 100 µm distance resolution and a typical accuracy of ±15 mm. A selectable response profile changes the balance between measurement speed and repeatability, with the switching rate following the chosen timing mode.

An M12 five-pin connector carries the 10–30 V DC supply and the configurable I/O of SICK DL35-B15552. Q1 operates as a digital output, while Q2 can be assigned as current, voltage, or digital output; IO-Link provides parameter and process-data exchange.

Teach controls on SICK DL35-B15552 define switching points and output behavior for the installed reflector path. The compact housing uses two M4 mounting holes, and the optical axis must remain aligned with the reflector over the full travel distance.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does SICK DL35-B15552 require reflective tape?
SICK DL35-B15552 reaches its documented 0.2–35 m range on Diamond Grade reflective tape, which returns the emitted laser signal to the receiver.
How do response settings change SICK DL35-B15552 behavior?
On SICK DL35-B15552, selecting a response profile changes response time and switching frequency, so speed and repeatability must be chosen together.
Which information is available through IO-Link on SICK DL35-B15552?
SICK DL35-B15552 exchanges distance process data and parameter information through IO-Link V1.1 on its configured communication channel.
Can Q2 on SICK DL35-B15552 be used as an analog output?
SICK DL35-B15552 allows Q2 to be configured as current, voltage, or digital output, while Q1 remains a separate digital output.
How should SICK DL35-B15552 be aligned?
Mount SICK DL35-B15552 securely, keep its optical axis on the reflector throughout travel, and teach the required switching or analog range after alignment.
Which parameters must be restored after installing a new SICK DL35-B15552?
For SICK DL35-B15552, restore the reflector type, Q1/Q2 assignments, IO-Link parameters, response profile, and taught distance values after confirming part 1057657.
