1612769

Overview

The SICK model 1612769 is a safety light curtain from the deTec series, designed for personnel and object protection in industrial automation. It features an IP69K housing rating suitable for hygienic environments with high-pressure cleaning. The device supports IO-Link communication for diagnostics and configuration. It includes Smart Box Detection for reliable rectangular object recognition without external sensors. The unit provides PL e (EN ISO 13849) performance level and Category 4 / SIL 3 (IEC 61508) safety integrity. It utilizes NFC technology for simplified setup and maintenance access.

Feature Summary

• Hygienic design with IP69K resistance to high-pressure water jets
• Integrated Smart Box Detection for automated object identification
• IO-Link interface for advanced diagnostic data exchange
• NFC-based configuration and status monitoring

Applications

• Food and beverage processing machinery safeguarding
• Pharmaceutical production line entry protection
• Cosmetics manufacturing equipment guarding
• Biotechnology facility safety zones

Procurement Notes

Verify that the specific order number matches the required resolution and sensing height for your application. Confirm compatibility with existing safety controllers regarding input requirements. Ensure the selected variant meets the necessary Performance Level (PL) and Safety Integrity Level (SIL) ratings defined by your machine's risk assessment documentation before finalizing procurement.

Selection Notes

Select this model when hygiene standards require frequent high-pressure washing of the sensor surface. Choose this unit if the application demands intelligent object differentiation to prevent unnecessary machine stops during material handling. Verify that the available mounting space accommodates the deTec housing dimensions and that the control system supports IO-Link master functionality for full feature utilization.

Part Context

This component belongs to the deTec safety light curtain family, which succeeds the M4000 series. It represents SICK's modern approach to safety devices by integrating smart detection capabilities directly into the hardware. The product line focuses on reducing downtime through intelligent restart interlocks and simplified commissioning processes via digital interfaces.

Replacement Considerations

When replacing legacy units, verify that the new device's mounting geometry fits existing brackets. Ensure the safety controller inputs are compatible with the deTec signal outputs. Check if firmware updates are required for the host PLC to interpret the new diagnostic data correctly.
