Overview

The SICK GL2S-N1312 is a retro-reflective photoelectric sensor designed for precise object detection in industrial environments. It features a compact square housing measuring 7.7 mm x 21.8 mm x 13.5 mm. The device utilizes a visible red PinPoint LED light source with a wavelength of 640 nm, producing a focused beam spot size of Ø 11 mm at a distance of 250 mm. The standard detection range extends from 0.03 m to 2.5 m when paired with the PL40A reflector, while the maximum operational range reaches up to 3 m under specific conditions. The sensor operates without manual adjustment mechanisms and offers an average service life of 100,000 hours at +25 °C.

Feature Summary

• PinPoint LED technology delivers a concentrated light spot for accurate detection of small targets
• Compact miniature housing design facilitates installation in space-constrained machinery
• Retro-reflective operating principle ensures reliable detection against specialized optical reflectors

Applications

• Automated assembly line positioning
• Packaging machine object presence verification
• Conveyor belt item counting
• Robotics end-of-arm tooling feedback

Procurement Notes

Verify that the required reflector type matches the application distance requirements, as the PL40A reflector is specified for the standard 2.5 m range. Confirm that the M12 connector interface aligns with existing cable assemblies. Ensure ambient lighting conditions do not exceed the sensor's interference immunity specifications. Check that the mounting geometry accommodates the 7.7 mm width dimension within the available panel cutout.

Selection Notes

Select this model when high precision is required for detecting small objects due to the PinPoint LED characteristic. Consider the limited adjustment-free operation if fixed alignment is feasible during installation. Evaluate the short minimum detection distance of 0.03 m to ensure objects do not enter the blind zone too closely. Compare against diffuse sensors if reflective surfaces are absent or inconsistent.

Part Context

This component belongs to the GL2S series of miniature photoelectric sensors manufactured by SICK. The series is characterized by its extremely small form factor and robust construction suitable for harsh industrial settings. The GL2S-N1312 specifically denotes the retro-reflective variant with red light emission, distinguishing it from infrared or laser-based models within the same product family.
