SICK GL10-N4111 Retroreflective Photoelectric Sensor 15m NPN M12 – Technical Product Guide

Overview

• PinPoint LED with a precise and highly visible light spot
• Compact housing design
• Power supply: 10 … 30 VDC, with PNP/NPN or relay output
• Robust sensor housing with reinforced metal mounting holes

Technical Overview of the SICK GL10-N4111

The GL10-N4111 employs the identical retroreflective sensing principle as the wider G10 series: the integrated PinPoint LED emits a focused visible red beam (625nm) toward the matched retroreflector (P250 or PL80A), which returns the beam directly to the co-located receiver aperture. Object presence is detected when the returning beam is interrupted, causing the NPN output transistor to switch. The dual-lens optical architecture physically separates transmit and receive optical paths, eliminating internal crosstalk and enabling high contrast detection.

The primary technical distinction of the GL10-N4111 relative to cable-output models (e.g., GL10-N1212) is the M12 4-pin male connector interface. This industrial-standard connector enables sensor replacement without cable cutting or rewiring – technicians simply unscrew the M12 coupling nut, extract the sensor, install the replacement unit, and reconnect the cable. This tool-free hot-swap capability significantly reduces mean time to repair (MTTR) in production environments where sensor replacement frequency is high. 

Five Key Technical Highlights:

• Maximum sensing range: 0.08m to 15m with PL80A reflector, or 0.08m to 12m with P250 reflector
• Switching output: NPN transistor,Light/dark switching, selectable via light/dark selector, max. output current 100mA
• Connection interface: M12 4-pin male connector – tool-free sensor exchange, wiring-system compatible
• Supply voltage: 10V DC to 30V DC (ripple <5Vpp), current consumption 20mA
•  Ingress protection: IP67 – fully dust-tight and waterproof to 1m immersion for 30 minutes

Industrial Applications of the SICK GL10-N4111 

1. Conveyor Systems and Automated Material Handling

The GL10-N4111 is optimally suited for automated conveyor systems, sortation lines, and warehouse management installations. The M12 connector facilitates neat cable routing within standardized cable trays and sensor junction boxes. Preventive maintenance and sensor replacement can be performed without disrupting adjacent wiring or taking the conveyor system offline for extended periods. The 15m sensing range covers wide conveyor gate spans and inter-conveyor transfer zones.

2. Safety Gating and Forklift Detection

At warehouse access gates, loading dock entrances, and restricted zone perimeters, the GL10-N4111 provides reliable beam-break detection of forklifts, reach trucks, and personnel. Fixed light-switching mode ensures deterministic output behavior: the NPN output deactivates on beam interruption and restores on beam re-establishment, providing a clean, unambiguous signal to gate controllers and safety PLCs.

3. Food and Pharmaceutical Packaging Lines

The IP67 rating supports use in production environments requiring periodic water washdown for hygiene compliance. The M12 connector simplifies sensor cleaning procedures compared to cable-entry designs. The GL10-N4111 reliably detects bottles, cartons, blister packs, and flexible pouches at 1,000Hz switching frequency – sufficient for typical packaging machine throughput rates. Operating temperature range down to –30°C permits installation in chilled storage environments.

4. Automated Parking Systems and Access Barriers

With a 15m sensing range, the GL10-N4111 provides comprehensive coverage of standard parking bay entrances and vehicle detection zones. When mounted with the PL80A reflector across a 6-8m wide entrance, the sensor maintains adequate operating reserve for reliable vehicle detection regardless of vehicle color or surface reflectivity (when relying on beam interruption rather than diffuse reflection).

5. Printing and Packaging Web Handling

In printing press and packaging machine applications, the GL10-N4111 detects material webs, media sheets, and film rolls on unwind and rewind stations. The 500µs response time and 1,000Hz switching frequency are compatible with high-speed web handling equipment. The M12 connector is particularly advantageous in printing environments where solvent exposure can degrade PVC cable jacketing over time.

Comparative Analysis – GL10-N4111 vs. GL10-N1212

Engineering selection guide: Select GL10-N4111 when the installation environment is well-characterized and consistent, the facility employs M12 wiring infrastructure, and rapid sensor replacement is operationally important. Select GL10-N1212 when field adjustment of detection sensitivity is required to accommodate variable target characteristics or reflector alignment conditions.

Frequently Asked Questions – SICK GL10-N4111

Q1: What is the list price of the SICK GL10-N4111?

Pricing is subject to order quantity and current availability. Contact AUMI at +84 917 991 589 for a competitive quotation and expert model selection support.

Q2: What type of cable is compatible with the GL10-N4111 M12 connector?

The GL10-N4111 uses an M12 4-pin male (plug) connector per Cd-066 wiring diagram. A corresponding M12 4-pin female (socket) cable assembly is required. AUMI supplies SICK-genuine M12 cable assemblies in lengths from 2m to 10m.

Q3: What is the difference between GL10-N4111 and GL10-N4112?

Both models share the same M12 4-pin male connector and NPN output. The main difference is the sensitivity adjustment:

• GL10-N4111: No potentiometer (fixed sensitivity), but still offers selectable Light/Dark switching via the built-in selector switch.
• GL10-N4112: Equipped with a 270° potentiometer for on-site sensitivity adjustment, plus selectable Light/Dark switching.

Recommendation: Choose GL10-N4111 if your application has stable conditions and you prefer a fixed, tamper-proof setting. Choose GL10-N4112 when you need the flexibility to fine-tune the detection threshold after installation (e.g., due to varying reflector distance, dust accumulation, or changing ambient light).

Q4: Can the GL10-N4111 detect transparent stretch-wrapped pallets?

Yes. The GL10-N4111 incorporates an integrated polarization filter and PinPoint LED technology, enabling reliable detection of pallets wrapped in transparent stretch film by discriminating between retroreflector returns and specular reflections from transparent packaging surfaces.
