Industrial Applications

1. Object Presence Detection in Food & Beverage Processing Lines

This sensor can reliably detect metallic containers or products on a conveyor belt within a food and beverage processing plant. Its 20mm flush mounting ensures it doesn't obstruct product flow, and the robust IP69K rating makes it ideal for frequent high-pressure, high-temperature washdowns.

Problem Solved

Prevents product jams and ensures accurate counting in environments requiring stringent hygiene and aggressive cleaning, where less protected sensors would fail due to water ingress or damage.

2. End-of-Travel Sensing for Automated Machining Centers

The NBB20-L2-Z0-V1 can serve as a precise end-of-travel sensor for metallic components in CNC machines or robotic tooling. Its 20mm rated operating distance and flush installation prevent interference with moving parts, while the 5-30VDC operating voltage is compatible with standard industrial control systems.

Problem Solved

Accurately determines the position of machine components, preventing over-travel and ensuring proper operation, even in environments with metallic dust and vibrations.

3. Metallic Component Verification on Assembly Lines

This inductive sensor is well-suited for verifying the presence of small metallic parts, such as screws, nuts, or metal inserts, at critical stages of an automated assembly line. The 2-wire NO output provides a simple signal for PLC integration, confirming correct part placement before the next assembly step.

Problem Solved

Ensures quality control by confirming the presence of essential metallic components, reducing assembly errors and rework. Its robust construction can withstand typical industrial assembly environments.
