Product Details
SICK GTB6-N1211 Photoelectric Switch Sensor
Product Introduction
The SICK GTB6-N1211 is a compact photoelectric proximity sensor
designed for precise object detection in diverse industrial and
commercial applications. Utilizing background suppression
technology, it ensures reliable sensing regardless of target
surface color or reflectivity, making it ideal for scenarios such
as crop position detection, product counting, and safety
protection. With a rugged IP67-rated housing and wide operating
temperature range (-25°C to +55°C), it performs consistently in
harsh environments, while its small form factor (12mm x 31.5mm x
21mm) enables installation in space-constrained locations.
Features
Background Suppression Technology: Eliminates interference from
background surfaces, ensuring detection depends only on target
distance (not color or reflectivity). Reliable for detecting dark
targets against bright backgrounds or vice versa.
Flexible Sensing Range: Operates within 35mm to 140mm (standard
range), with a maximum adjustable range of 5mm to 250mm, adapting
to varied object sizes and distances.
Compact & Durable Design: IP67-rated enclosure resists dust and
water, suitable for wet or dusty industrial environments.
Lightweight (60g) and small dimensions facilitate installation in
tight spaces.
User-Friendly Indicators: Green LED indicates power supply
activation; yellow LED shows light receiving status, simplifying
setup and troubleshooting.
Adjustable Settings: Equipped with a sensitivity potentiometer (+
for longer distance, - for shorter) and light/dark switch
(L=light-on, D=dark-on), allowing customization for specific
application needs.
Wide Compatibility: 10-30V DC power supply, 30mA power consumption,
and reverse-polarity/short-circuit protection ensure safe
integration with industrial control systems.
