Overview of GL2S-N1312 SICK Photoelectric Sensor
The GL2S-N1312 belongs to SICK’s G2 series – one of the most widely deployed miniature photoelectric sensor families in industrial automation. The device operates on the retro-reflective principle, where the emitter and receiver are housed in the same unit; the light beam travels to the reflector and returns. When an object interrupts the beam, the output is triggered.
A key design feature is the dual lens system, which establishes a minimum detection distance to the reflector, preventing false detection from nearby objects. The 640 nm PinPoint LED generates a focused, visible red light spot (Ø 11 mm at 250 mm distance), simplifying alignment even in complex industrial lighting environments.
With an ABS plastic housing measuring just 7.7 × 21.8 × 13.5 mm and a pre-wired 3-wire, 2m PVC cable, the GL2S-N1312 offers tool-free, rapid installation in space-constrained mounting positions without additional connectors.

Industrial Applications of GL2S-N1312 Photoelectric Sensor
With a 3m sensing range, miniature footprint, and IP67 rating, the GL2S-N1312 addresses a broad range of industrial applications in Vietnam:
- Food & Pharmaceutical Packaging Lines: Mounted on conveyor frames to detect products passing at production speed. The PinPoint LED clearly identifies small items (boxes, vials, pouches) on high-speed belts. NPN output is natively compatible with PLCs commonly used in Vietnam (Mitsubishi, Omron, Siemens).
- Automated Product Counting Systems: 800 Hz switching frequency ensures no product is missed even on high-speed lines. Response time < 0.6 ms suits precision pulse-counting applications.
- Industrial Packaging Machines & Printers: The 7.7 mm width allows installation in narrow machine gaps. GL2S-N1312 detects labels, pouches, and cartons within compact machine frames where standard sensors cannot fit.
- Logistics Conveyor Sorting: 3m range is well-suited for wide detection gates on sorting lines. IP67 handles humid warehouse environments and periodic water wash-downs.
- Factory Entry/Exit Gates and Access Control: Installed on both sides of gates to detect personnel or forklifts at up to 3m.
AUMI has supplied GL2S series sensors for numerous packaging automation and logistics projects in Vietnam.

Need flexible Light/Dark switching, complex PLC logic |
Selection Guidance:
Choose GL2S-N1312 if: your application requires a simple fixed light-switching logic (e.g., object presence detection, pulse counting), and you want to save cost with the reflector already included. Choose GL2S-N2311 if: your system needs to switch between light-on and dark-on logic, or if your PLC requires two independent signal outputs for the same sensing point.
