1067861

Overview

The SICK 1067861 is a photoelectric sensor belonging to the WTB9 series, designed for industrial object detection. It operates as a through-beam receiver unit, utilizing a red LED light source with a wavelength of approximately 650 nm. The device features an analog output signal, specifically a 4-20 mA current loop, which provides continuous distance measurement or intensity monitoring capabilities. It supports PNP switching outputs and includes IO-Link communication interface for parameterization and diagnostics. The sensor housing is constructed from plastic materials, offering protection ratings suitable for harsh industrial environments, typically IP67 or higher, ensuring reliable performance against dust and water ingress.

Feature Summary

• Provides analog 4-20 mA output for precise distance or intensity monitoring applications
• Integrates IO-Link interface for advanced device configuration and diagnostic data exchange
• Features robust plastic housing designed for durability in demanding industrial settings
• Combines PNP switching functionality with analog signaling for versatile system integration

Applications

• Continuous level monitoring in bulk material handling systems
• Precision positioning tasks requiring variable distance feedback
• Automated assembly lines needing both presence detection and proximity data
• Packaging machinery integrating analog control loops with digital diagnostics

Procurement Notes

Verify the specific suffix codes on the order confirmation to ensure the correct cable length, connector type, and optical range match your installation requirements. Confirm that the power supply voltage aligns with the device specifications, typically 10-30 V DC. Ensure the receiving unit is paired with the corresponding transmitter model from the same series to guarantee optimal signal integrity and detection range. Check for any required mounting accessories separately.

Selection Notes

Select this model when analog distance feedback is required alongside standard switching functions. The IO-Link capability makes it suitable for Industry 4.0 environments requiring predictive maintenance data. Consider the operating range and background suppression needs when choosing between different variants within the WTB9 series. Ensure the environmental conditions, such as ambient light interference, are within the sensor's specified tolerance limits for stable operation.

Part Context

This component is part of SICK's WTB9 series of through-beam sensors, known for high reliability and flexible configuration options. The series is widely used in factory automation for safety-critical and non-safety-critical detection tasks. The 1067861 variant specifically targets applications needing analog output, distinguishing it from standard binary output models in the same product family.

Replacement Considerations

Direct replacements must maintain the 4-20 mA analog output and IO-Link interface. Verify mechanical dimensions and mounting hole patterns to ensure compatibility with existing brackets. Check if the new model supports the same voltage range and light source type to avoid recalibration issues.
