SICK 1057659 DR35-B15522 IO-Link Laser Distance Sensor

Technical Overview

The SICK DR35-B15522 is a time-of-flight distance sensor for diamond-grade reflective tape, with a specified measuring range of 200–35,000 mm. Its visible 658 nm Class 1 laser produces a typical 15 × 15 mm spot at 2 m. Five selectable speed settings provide separate response specifications for lateral target entry and output times for continuous distance changes. Two push-pull PNP/NPN outputs report configured distance conditions, while IO-Link V1.1 supports process data, parameterization and diagnosis at 38.4 kbit/s. Digital teach-in, output inversion and distance, window or intervening-object modes adapt the switching behavior. The IP65/IP67 ABS/PC housing has PMMA optics and an M12 five-pin connector; IO-Link operation requires supply above 18 V.

Class 1 red-laser time-of-flight sensor for 200–35,000 mm on diamond-grade reflective tape, with IO-Link V1.1 and two push-pull outputs.

Industrial Applications

1. Changing distance-sensor settings for a new machine recipe

A machine that alternates between reflector positions can use an IO-Link master to parameterize the sensor for the selected recipe. Digital teach-in, output inversion and selectable speed settings establish the intended switching behavior for each setup. External commissioning logic coordinates those changes with machine state and verifies the reflective-tape target within the documented measuring range before production resumes.

Problem Solved

Parameter access lets external machine logic manage sensor settings alongside the selected recipe, reducing reliance on repeated manual adjustment when the distance conditions change.

2. Confirming a reflector-equipped carriage in a docking window

A carriage can carry diamond-grade reflective tape facing the fixed sensor along its travel path. Window mode reports whether the target lies within taught distance limits, and the two push-pull outputs connect to external sequencing inputs. Commissioning accounts for the installed distance, selected speed and repeatability curve when defining a docking band appropriate to the mechanism.

Problem Solved

A taught distance window provides external sequencing logic with a docking-position condition, helping distinguish the expected carriage location from travel outside that band.

Distance window Reflective tape Docking position

3. Detecting an object entering a defined reflector path

A transfer station can place a fixed reflective-tape target behind the intended material path and select the object-between-sensor-and-background mode. An entering object changes the optical condition before the background reflector. The configured digital output provides a process event for external control, with entry speed and spacing assessed against the selected lateral-entry response and installed geometry.

Problem Solved

The defined background reference supports an intervening-object event for external process logic, helping detect entry into the monitored material path using the configured optical arrangement.
