1091691

Overview

The SICK part number 1091691 corresponds to the GL2S-N1312 retro-reflective photoelectric sensor. This device utilizes a visible red light source with a wavelength of 640 nm and features a PinPoint LED projector. The sensor is designed for use with the PL40A reflector, providing a detection range from 0.03 m to 2.5 m and a maximum detection range of up to 3 m. It has a square housing shape with dimensions of 7.7 mm in width, 21.8 mm in height, and 13.5 mm in depth. The optical spot size measures approximately Ø 11 mm at a distance of 250 mm. The unit operates without external adjustment mechanisms.

Feature Summary

• Utilizes a PinPoint LED technology to generate a focused light spot for precise object detection.
• Designed specifically for retro-reflective operation using compatible reflectors such as the PL40A.
• Features a compact square housing suitable for installation in space-constrained environments.

Applications

• Object detection in automated industrial machinery
• Position sensing in packaging equipment
• Presence detection on conveyor systems

Procurement Notes

Verify the specific ordering designation matches the required configuration. Confirm that the necessary reflector, such as the PL40A or PL20A, is included or ordered separately. Ensure the application environment is compatible with the visible red light spectrum and the specified detection distances. Check technical drawings for mechanical fitment requirements before finalizing the purchase order.

Selection Notes

Select this model when a compact form factor is required for retro-reflective sensing applications. Consider the PinPoint LED feature if high precision is needed at short distances. Evaluate the 640 nm wavelength suitability against ambient lighting conditions. Compare the 2.5 m standard detection range against the system's operational requirements to ensure adequate coverage.

Part Context

This component belongs to the GL2S series of photoelectric sensors manufactured by SICK. The series is characterized by small dimensions and versatile functionality for various industrial automation tasks. The GL2S-N1312 variant specifically addresses needs for retro-reflective detection with a visible light source, distinguishing it from infrared models within the same product family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing mounting hardware and wiring configurations when considering alternative sensors from the same manufacturer or other brands.
