Overview

The SICK WTD20E-W1145 is a block-shaped background suppression photoelectric sensor from the DeltaPac series. It features a red light source and an NPN output type. The detection range is specified as 30 mm to 40 mm. Electrical parameters include a maximum DC voltage of 30V and a maximum current of 100 mA. The device utilizes a 2-meter cable for electrical connection. It offers an IP67 protection rating and operates within a temperature range of -40°C to +55°C. The housing is constructed from plastic material.

Feature Summary

• Background suppression technology ensures reliable object detection by ignoring distant backgrounds.
• Compact block-shaped design suitable for space-constrained industrial applications.
• Integrated 2-meter cable provides direct connectivity without additional wiring requirements.

Applications

• Automated assembly line monitoring
• Packaging machine object detection
• Conveyor belt presence sensing

Procurement Notes

Verify the specific part number WTD20E-W1145 against official SICK documentation to confirm compatibility with existing control systems. Ensure that the NPN output configuration matches the input requirements of the connected PLC or controller. Confirm that the 30V maximum DC voltage limit aligns with the system power supply specifications. Check that the 2-meter cable length meets the installation distance requirements between the sensor and the control unit.

Selection Notes

Select this model when background suppression is required for precise detection at short distances. The NPN output is suitable for standard industrial controllers accepting sinking inputs. Consider the IP67 rating for environments requiring protection against dust and water jets. Verify that the operating temperature range of -40°C to +55°C covers the intended application conditions.

Part Context

This component belongs to the SICK DeltaPac series, which focuses on compact and versatile photoelectric sensors. The WTD20E variant specifically addresses applications needing reliable background suppression in a small form factor. It is designed for integration into automated machinery where consistent performance at fixed distances is critical.

Replacement Considerations

Consult official SICK cross-reference guides for verified substitute models. Ensure any replacement maintains the same background suppression functionality, NPN output type, and detection range specifications.
