SICK GTB6-N1211 Photoelectric Proximity Sensor NPN 10-30V DC

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.
