SICK 1063646 WTB2SC-2P3274A00 IO-Link Line-Spot BGS Sensor

Technical Overview

The SICK WTB2SC-2P3274A00 is a background-suppression photoelectric sensor with a 640 nm red PinPoint LED and a 2.2 × 9 mm line-shaped spot at 45 mm. Reference-white sensing is 10–70 mm, maximum range is 4–90 mm and the preset distance is 45 mm. IO-Link V1.1 supports parameterization, two switching-signal process bits and device-status diagnosis. Base logics provide selectable logic, timer and inversion functions, with response times specified separately for SIO Direct, SIO Logic and full IO-Link operation. The configurable PNP device uses a 200 mm PVC lead with an M8 four-pin male connector, an IP67 ABS/PC housing and PMMA optics. Pin 4 must not be connected to another output.

Industrial Applications

1. Detecting a perforated component at a presentation station

A presentation station can orient the red line spot across a representative perforated component at a controlled distance. The manufacturer lists perforated objects among this model’s detection roles. Background suppression and IO-Link adjustment establish the target condition, while external sequencing reads the configured PNP output after presentation. Setup assesses the actual hole pattern, remission and placement tolerance against the line-spot geometry.

Problem Solved

The line-shaped optical observation provides a presence condition for external sequencing on a perforated target, helping distinguish the expected component presentation from an empty position.

Perforated targets Line spot Background suppression

2. Changing the detection settings with an assembly recipe

An assembly station that changes component presentations can use an IO-Link master to set the sensor parameters alongside the selected machine recipe. Programmable light/dark behavior and configurable pin 2 functions adapt the electrical event to the process. External changeover logic coordinates the update while the machine is in its setup state and verifies the new presentation before operation resumes.

Problem Solved

Remote parameter access lets external changeover logic align sensing behavior with the selected assembly recipe, reducing repeated local adjustment when the target presentation changes.

Recipe settings IO-Link V1.1 Configurable pin 2

3. Delaying a signal until a presented object remains detected

A transfer position can use the sensor’s switch-on delay to require a detected object to remain present before issuing the configured event. Base logics and inversion establish the useful signal behavior, and external sequencing then evaluates that output. The timing design uses the SIO Logic or full IO-Link response and frequency for the selected operating mode rather than the faster SIO Direct figures.

Problem Solved

An internal switch-on delay creates a persistence-based detection event, helping external transfer sequencing distinguish a sustained presentation from a brief passage through the optical field.
