Photoelectric retro-reflective sensor GL6-N1212 SICK 6 m NPN IP67
Overview
The GL6-N1212 is a retro-reflective photoelectric sensor from SICK’s G6 series, offering a sensing range of up to 6 m, NPN output, and selectable Light/Dark switching. Delivered as a complete ready-to-install kit including the P250 reflector and stainless steel mounting bracket BEF-W100-A, it significantly reduces installation time and accessory costs.
With its compact design, PinPoint red LED, and polarization filter, the GL6-N1212 delivers reliable performance in demanding industrial environments.
Product Overview – GL6-N1212
The GL6-N1212 belongs to SICK’s compact G6 miniature sensor family (Germany). It features a dual-lens optical system combined with a 650 nm PinPoint red LED and polarization filter, producing a highly focused light spot (Ø 8 mm at 350 mm). This enables stable and precise object detection even on challenging surfaces.
The rectangular housing measures just 12 × 31.5 × 21 mm. Sensitivity is adjusted via a 270° potentiometer, and status is clearly indicated by integrated LEDs. The standout advantage of the GL6-N1212 variant is the complete accessory kit (P250 reflector + BEF-W100-A stainless steel bracket) included in the box, making it the ideal choice for fast project deployment or direct replacement.

Frequently Asked Questions (FAQ)
Q1. Can the GL6-N1212 reliably detect dark, glossy, or transparent objects?
Yes. The combination of PinPoint red LED (650 nm), polarization filter, and dual-lens system ensures stable detection across a wide variety of surfaces, including dark, shiny metallic, and some transparent objects.
Q2. Which reflector should be used to achieve the maximum 6 m sensing range?
SICK recommends the PL80A reflector for maximum range. The included P250 reflector delivers excellent performance for most applications and is particularly suitable for space-constrained installations.
Q3. What is the difference between GL6-N1212 and GL6-N1211S27?
Both models have identical technical specifications. The GL6-N1212 includes the P250 reflector and stainless steel bracket BEF-W100-A (complete set). The GL6-N1211S27 contains the sensor only.
Q4. Is the sensor suitable for dusty, wet, or wash-down environments?
Yes. With an IP67 protection rating, the sensor is fully dust-tight and resistant to powerful water jets, making it ideal for food processing, packaging, logistics, and wash-down applications.
Q5. How do you set Light ON / Dark ON mode and adjust sensitivity?
Use the rotary switch on the sensor housing to select Light ON or Dark ON mode. Sensitivity is adjusted using the 270° potentiometer. The sensor also features clear LED status indicators.
