SICK GTB6-P3211 Photoelectric Sensor, 250mm range

The SICK GTB6-P3211 photoelectric sensor is a compact, background suppression sensor engineered for precise object detection in space-limited industrial automation and machine vision setups.

Overview and Applications:

The SICK GTB6-P3211 miniature photoelectric sensor combines reliable background suppression with a 5 mm to 250 mm detection range and a visible 650 nm red light. As part of the SICK GTB6 series of photoelectric proximity sensors, it excels in material handling, packaging lines, and assembly automation where false trigger reduction is critical.

• Operating range: 5–250 mm
• Dimensions: 12 mm × 31.5 mm × 21 mm
• Weight: 2 grams
• Ingress protection: IP67

Key Features of the SICK GTB6-P3211:

This miniature photoelectric proximity switch uses advanced background suppression to detect objects in front of fixed surfaces like conveyor frames, filtering out unwanted background signals automatically. The 10 meter pre-wired cable increases installation flexibility across various machinery layouts.

Usage and Mounting Guidance:

The SICK GTB6-P3211 can be installed in tight locations thanks to its lightweight and compact housing. Top-fastening holes support easy integration on mounting brackets typical to the GTB6 series. For wiring, reference the SICK photoelectric sensor wiring guide for standard photocell hookup, available in the photoelectric sensors section. Maximum cable length is 10 meters, reducing voltage drop over long runs.

When to Choose the GTB6-P3211:

Choose the SICK GTB6-P3211 miniature photoelectric sensor when high precision background suppression is required in space-constrained environments, or when competing retro-reflective or through-beam sensors cannot reliably ignore background objects. Alternative GTB6 models within the SICK family provide different sensing distances and output options if other configurations are needed.
