1048188

Overview

The SICK 1048188 is a photoelectric sensor belonging to the WFS3-40 series, designed for industrial object detection. It operates using diffuse reflection technology with an integrated receiver and transmitter. The device utilizes red LED light sources for reliable sensing. It features a PNP switching output configured in NO/NC mode, ensuring compatibility with standard PLC inputs. The unit provides a maximum switching distance of 250 mm when detecting standard targets. It is housed in a robust plastic enclosure rated IP67 for protection against dust and water ingress, suitable for demanding factory environments.

Feature Summary

• Diffuse reflection sensing principle with integrated optical components
• Red LED illumination for consistent target detection
• PNP NO/NC switching output configuration
• IP67 environmental sealing for industrial durability

Applications

• Automated assembly line object presence verification
• Packaging machinery level detection
• Conveyor belt item sorting and counting
• Industrial safety gate monitoring

Procurement Notes

Verify that the specific order matches the WFS3-40 series designation and PNP output type. Confirm the required cable length or connector type if not included in the base package. Ensure the operating voltage range aligns with the facility's 24V DC supply standards. Check for any specific mounting bracket requirements compatible with the sensor's housing dimensions.

Selection Notes

Select this model when diffuse reflection geometry is preferred over retro-reflective setups due to space constraints on the opposing side. The PNP NO/NC output offers flexibility for both sourcing and sinking logic connections. Consider the 250 mm switching distance as the limiting factor for long-range applications where other series may be more appropriate.

Part Context

This component is part of SICK's WFS3-40 product family, which focuses on compact photoelectric sensors for general-purpose automation. The series emphasizes ease of installation and reliable performance in standard industrial settings. It complements larger sensor arrays by providing cost-effective solutions for individual station monitoring tasks.

Replacement Considerations

Direct substitutes include updated revisions within the same WFS3-40 series from SICK. Cross-brand equivalents require matching diffuse reflection technology, PNP output polarity, and IP67 rating. Verify mechanical footprint compatibility before integrating alternative manufacturers' devices.
