Overview
The Pepperl+Fuchs US-2111 ultrasonic proximity sensor delivers non-contact distance measurement and object detection for demanding industrial automation environments. Built on Pepperl+Fuchs’ proven ultrasonic sensing technology, the US-2111 provides stable, accurate detection independent of surface color, reflectivity, or translucency—making it ideal for applications where photoelectric sensors fall short.
Key Features
- Non-contact ultrasonic detection technology — no physical contact required
- Consistent performance across materials, colors, and surface finishes
- Compact form factor suitable for tight installation spaces
- Analog and digital output options for flexible integration
- Temperature-stable operation in industrial environments
- Industry-standard M8 or M12 connector options
Technical Specifications
Exact specifications for the US-2111 should be verified with the manufacturer’s current datasheet. Typical characteristics of Pepperl+Fuchs ultrasonic sensors include:
- Detection range varies by model variant
- Supply voltage: 18–30 VDC (standard industrial)
- Output types: Analog (0–10 V, 4–20 mA) or digital switching
- Operating temperature: −10 to +50°C (verify for your variant)
- Frequency: ~400 kHz ultrasonic sensing
- Response time: Adjustable, typically 8–60 ms range
- Mounting: Threaded or flush-mount options
Typical Applications
- Conveyor belt level detection and material handling
- Robot collision avoidance and proximity warning systems
