Core Product Specifications

Key Performance Advantages

1. Compact size

As a member of the SICK W8 miniature sensor series, WTB8-P2231 has been optimized for space-constrained application scenarios.

Its ultra-compact housing can be easily integrated into small equipment and automated production lines without occupying extra installation space.

2. Optimized ASIC chip

The optimized ASIC chip brings excellent background suppression capability, which can accurately identify target objects with complex backgrounds or different reflectivity and avoid false triggering caused by background interference.

3. High-power visible red LED light source

It adopts an imported high-power visible red light LED light source with a clear light spot that is easy to align during installation and debugging, which greatly reduces the time of on-site debugging.

4. Suitable for harsh operating conditions

The product meets the IP67 protection standard, can work stably in harsh industrial environments such as dust, oil fume and moisture.

It also has strong resistance to mechanical vibration and impact, with an average service life of more than 50,000 hours under normal use, which significantly reduces the frequency of equipment maintenance and replacement.

To help you quickly select the right model for your application, we have sorted out the comparison of the main parameters of common models in the W8 series as follows:

From the comparison table, SICK WTB8-P2231 has an advantage in the combination of sensing distance, output type and connection mode.

It is the most versatile and cost-effective model in the W8 series, which can adapt to most small-size object detection scenarios.

Recommended Matching & Application Scenarios

Recommended Connector & Cable Matching

WTB8-P2231 uses a 3-pin M8 connector.

For customers who need to extend the wiring, we recommend matching the original SICK cables, the common models are as follows:

· DXM08-02MA050PG0: 3-pin M8 female connector, 0.5m cable length, suitable for short-distance wiring in small equipment

· DXM08-02MA200PG0: 3-pin M8 female connector, 2m cable length, suitable for conventional installation distance

· DXM08-02MA500PG0: 3-pin M8 female connector, 5m cable length, suitable for long-distance wiring from sensor to control cabinet

The above matching cables are also in stock all the year round, you can add them directly to the order when purchasing, which saves your time of looking for matching accessories.

Typical Application Scenarios

WTB8-P2231 is suitable for the following automation scenarios:

Presence detection of small parts on automated assembly lines

Counting detection of packaging products on packaging lines

Positioning detection of suction cups on industrial robotic arms

Material level detection on small material silos, detection of label gaps in labeling machines

Detection of door switches in automated equipment

In the packaging and printing industry, this sensor can accurately identify paper labels with different reflectivity, and will not be interfered by the color of the background paper, which is very suitable for high-speed labeling machine applications.

FAQ

Q: Does the sensing range of the SICK WTB8-P2231 vary based on object color?

A: The maximum sensing range of 30–300 mm for the WTB8-P2231 is measured using a standard white object with 90% diffuse reflectance (DIN 5033 standard white).

For dark-colored or low-reflectivity objects, the actual detectable range will be reduced. The background suppression function ensures stable detection within the set range, regardless of object color or surface quality.

Q: What should be considered during wiring?

A: Please note the following points regarding wiring:

Verify power supply voltage: The operating voltage is 10–30 V DC; do not connect to an AC power source.

Verify output type: This model features PNP output; the wiring method differs from that of NPN models.

Verify polarity: Wire strictly according to the pin definitions.

Protection circuits: The sensor includes built-in protection for A (reverse polarity protection for power supply), B (reverse polarity protection for inputs/outputs), and D (output overcurrent and short-circuit protection).

Power off before wiring: Always disconnect the 24 V DC power supply before performing wiring.

Q: What accessories are included?

A: The WTB8-P2231 comes with one BEF-W100-A stainless steel mounting bracket.

The sensor itself does not include an M8 connection cable; this must be purchased separately.
