Industrial Applications

1. Automated Conveyor System Object Detection

Detecting the presence or absence of metallic objects on a conveyor belt in manufacturing or logistics environments.

Problem Solved

Reliably identifies metallic items up to 8mm away, even in dusty or wet conditions (IP67), ensuring proper sorting, counting, or process triggering. The non-flush mount makes it adaptable to various mounting positions on the conveyor structure.

2. Machine Tool Position Monitoring (Non-Contact Limit Switch)

Providing precise, non-contact end-of-travel detection for metallic components within machine tools, such as CNC machines or robotic arms.

Problem Solved

Acts as a robust, wear-free limit switch for metallic machine parts, operating reliably with a standard 20-253V AC supply. Its M18 form factor allows for easy integration into existing machine designs, and the IP67 rating protects against coolant and swarf.

3. Industrial Door/Gate Position Sensing

Monitoring the open/closed status of metallic industrial doors or gates in factories, warehouses, or processing plants.

Problem Solved

The 8mm sensing range is suitable for detecting the proximity of a metallic door frame or flag, providing reliable feedback to control systems. The IP67 rating ensures durability in harsh industrial environments, and the wide AC voltage range simplifies electrical integration.
