Industrial Applications

1. High-Speed Small Part Detection on Production Lines

This sensor is ideal for detecting the presence or absence of small, rapidly moving components on automated assembly lines, particularly those with limited mounting space. Its ability to detect black objects reliably is crucial for diverse component materials.

Problem Solved

The 0.5 ms response time ensures no parts are missed even at high production speeds, while its ultra-slim profile (3.5 mm thick) allows integration into compact machinery where conventional sensors would not fit.

2. Conveyor Belt Jam Detection in Wet Environments

The EX-14A-PN can be used to monitor material flow on conveyor belts in environments prone to moisture or dust, triggering an alert or shutdown if a jam occurs.

Problem Solved

The IP67 rating ensures robust operation in industrial settings with water spray, dust, or occasional submersion. Its 2-25mm sensing range is suitable for detecting various material sizes, and its diffuse-reflective nature allows for direct installation without a separate reflector.

3. Robotic Gripper Position and Object Confirmation

Integrated into the jaws of robotic grippers, this sensor can confirm the successful grasping of an object or verify the gripper's open/closed position for precise automation tasks.

Problem Solved

The extremely compact dimensions (14.5 x 10 x 3.5 mm) are perfect for mounting on robotic end-effectors without adding significant bulk or interfering with movement. The short sensing range (2-25mm) provides precise feedback for intricate manipulation.
