1613889

Overview

The SICK model 1613889 is a WTB4S-3N1361 proximity optical sensor designed for industrial object detection. It operates within a supply voltage range of 10 V to 30 V and utilizes an NPN output configuration. The functional sensing distance spans from 4 mm to 180 mm, corresponding to approximately 0.157 inches to 7.087 inches. This device employs a direct reflection principle suitable for detecting various material surfaces.

Feature Summary

• Utilizes a direct reflection optical sensing principle for reliable object detection
• Features an NPN switching output interface for standard PLC integration
• Operates on a wide DC supply voltage range supporting common industrial standards

Applications

• Automated packaging machinery line monitoring
• Conveyor belt presence detection systems

Procurement Notes

Verify the specific ordering number against official SICK documentation to ensure correct output type and housing variant. Confirm that the NPN output specification matches your control system requirements. Check for any updated suffix codes that may indicate minor design revisions or regional compliance differences before finalizing procurement orders.

Selection Notes

Select this component when a compact optical sensor with a moderate detection range is required. The NPN output is suitable for sinking current applications. Ensure the mounting environment allows for the specified 4 mm minimum sensing distance. Consider the square housing dimensions for spatial constraints in tight installation areas compared to cylindrical alternatives.

Part Context

This part belongs to the WTB4S series of rectangular optical sensors from SICK. The series is engineered for general-purpose proximity detection in automation environments. The model number 1613889 specifically identifies the configuration with NPN output and the defined sensing range parameters within this product family.

Replacement Considerations

Consult the official SICK replacement guide for cross-references. Verify mechanical mounting hole patterns and electrical pin assignments match existing infrastructure before substituting.
