- Stable object detection up to 15m using a double-lens system and PL80A reflector
- NPN output with selectable Light-ON / Dark-ON modes for seamless integration with most PLCs and industrial controllers
- PinPoint red LED (625 nm) with long service life of approximately 100,000 hours
- IP67-rated housing – fully dust-tight and water-resistant, ideal for harsh, wet production environments
- Integrated polarization filter effectively suppresses interference from reflective object surfaces
- Compact design (20 × 50 × 39 mm), high switching frequency of 1,000 Hz, and response time ≤ 500 µs
The GL10-N1111 from SICK is a retro-reflective photoelectric sensor featuring a double-lens optical system. It achieves a maximum sensing distance of 15m with the PL80A reflector, NPN output, and operates on 10–30V DC. Equipped with a polarization filter, PinPoint red LED, and IP67 protection, it is perfectly suited for object detection in production lines, conveyors, warehouses, and automated gates.
Product Overview
The GL10-N1111 belongs to SICK’s popular G10 series of photoelectric sensors. Its key advantage lies in the retro-reflective principle combined with a double-lens system, which significantly improves detection stability and eliminates false signals caused by reflective surfaces on the target object.
With a sensing range up to 15m (using PL80A reflector) and a switching frequency of 1,000 Hz, the sensor is ideal for high-speed conveyor applications. Light-ON and Dark-ON modes can be easily selected via wiring or push-button. The robust ABS/PMMA housing with IP67 rating ensures reliable operation in environments with moisture, dust, and vibration. Dual LED status indicators (yellow and green) provide clear on-site diagnostics.

Frequently Asked Questions (FAQ)
Q1: What is the price of the GL10-N1111?
A: Price depends on quantity and contract terms. Please contact AUMI for the best quotation and technical consultation.
Q2: Which reflectors are compatible?
A: The sensor works with PL80A (max 15m), P250 (12m), PL40A, PL30A, PL20A, etc. AUMI provides expert advice on reflector selection.
Q3: What is the difference between GL10-N1111 (NPN) and GL10-P1111 (PNP)?
A: NPN (sinking) is typically used with Siemens, Omron, Mitsubishi PLCs in sink configuration. PNP (sourcing) is used in source configuration.
Q4: Can it detect transparent objects?
A: The polarization filter improves detection of some transparent objects (e.g., PET bottles, glass) compared to diffuse sensors. For highly transparent materials, through-beam sensors are recommended.
