1082973

Overview

The SICK model 1082973 is a WTB4L-3P2461 photoelectric sensor, part of the WTB4L series designed for reliable object detection in industrial automation. This specific unit features a PNP normally open output and utilizes a light/dark switching mode to ensure accurate sensing across varying surface reflectivities. It employs retroreflective technology with an integrated polarizing filter to effectively detect glossy or transparent objects that typically challenge standard sensors. The device operates on a DC supply voltage and includes a teach-in function for easy setup. Its compact housing allows for installation in space-constrained environments while maintaining robust performance against ambient light interference.

Feature Summary

• Utilizes retroreflective technology with integrated polarizing filter for detecting glossy surfaces
• Features PNP normally open output for direct PLC integration
• Includes teach-in functionality for simplified configuration and range adjustment
• Designed with a compact housing suitable for tight installation spaces

Applications

• Detection of transparent bottles or containers on packaging lines
• Monitoring of glossy labels on moving substrates
• Object presence verification in automated assembly stations
• Level detection in material handling systems with reflective targets

Procurement Notes

Verify the exact order number 1082973 against your system requirements before purchase. Confirm that the PNP output type matches your controller's input specifications. Ensure the operating voltage range aligns with your plant's power distribution. Check the cable length and connector type if pre-wired variants are required. Validate environmental ratings such as IP protection against your installation site conditions.

Selection Notes

Select this model when dealing with highly reflective or transparent targets where standard diffuse sensors fail. The integrated polarizer is critical for distinguishing the target from background reflections. Consider the WTB4L series if retroreflective operation offers better range than diffuse alternatives. Evaluate the need for PNP outputs versus NPN based on your existing control infrastructure. Assess whether the fixed focus distance meets your application's working range requirements.

Part Context

This component belongs to SICK's WTB4L series of retroreflective photoelectric sensors. These sensors are engineered for high reliability in demanding industrial environments. The series is known for its robustness against ambient light and its ability to handle challenging materials. Model 1082973 represents a specific configuration within this family, tailored for applications requiring precise detection of difficult surfaces using polarized retroreflection.

Replacement Considerations

Check for updated revisions of the WTB4L series which may offer improved environmental sealing or updated output circuitry. Verify compatibility with existing mounting brackets and wiring harnesses. Ensure that any substitute maintains the same polarizing filter capability for glossy object detection. Confirm that the replacement supports the same teach-in procedures to minimize downtime during swap-out.
