Overview

The SICK WTD20E-W1145 is a block-shaped photoelectric sensor from the DeltaPac series, designed for background suppression applications. It features a detection range of 30 mm to 40 mm and utilizes red light as its source. The unit provides an NPN output type and includes a 2-meter electrical cable connection. It operates on a maximum DC voltage of 30V with a maximum current of 100 mA. The sensor offers IP67 protection and functions within a temperature range of -40°C to +55°C.

Feature Summary

• Background suppression capability ensures accurate detection regardless of object color or surface reflectivity.
• Compact block-style housing design facilitates integration into space-constrained industrial environments.
• Integrated 2-meter cable simplifies installation by eliminating the need for separate connectors.

Applications

• Object detection in automated assembly lines
• Position verification in packaging machinery
• Presence sensing in material handling systems

Procurement Notes

Verify that the specific application environment does not exceed the maximum operating temperature of +55°C or drop below -40°C. Confirm that the control system input logic matches the NPN output configuration. Ensure the mounting location allows for the required 30 mm to 40 mm sensing distance without obstruction. Check that the power supply voltage remains within the 30V DC limit to prevent component damage.

Selection Notes

Select this model when precise background suppression is required for objects within a narrow 30-40 mm range. Choose this variant if an NPN output interface is mandated by the existing PLC or controller architecture. Consider this part for applications requiring a fixed sensing distance rather than adjustable ranges, which simplifies setup procedures. Verify compatibility with the available 2-meter cable length before finalizing the selection.

Part Context

This component belongs to the SICK DeltaPac series, which specializes in compact photoelectric sensors for industrial automation. The WTD20E designation indicates a block-style form factor optimized for tight mounting spaces. The product line emphasizes reliability in harsh environments through robust plastic housing and high ingress protection ratings.

Replacement Considerations

Consult official SICK documentation for direct cross-references. Ensure any substitute maintains identical background suppression functionality and NPN output polarity. Verify that replacement units support the same 30-40 mm detection range and IP67 rating.
