Industrial Applications

1. High-Speed Small Component Detection on Automated Assembly Lines

The ultra-compact dimensions (8.2 x 19 x 10.5 mm) and rapid 0.5 ms response time enable the precise detection of small objects or components moving at high speeds on automated assembly lines, particularly in confined spaces where larger sensors are impractical. The 5-160 mm sensing range provides flexibility in sensor mounting relative to the target.

Problem Solved

Ensures accurate and rapid detection of miniature parts in space-constrained, high-throughput manufacturing processes, preventing jams or misalignments.

2. Non-Contact Liquid Level Monitoring in Small Industrial Tanks

With its IP67 rating and diffuse reflective sensing capability, this sensor is suitable for non-contact level detection of opaque or translucent liquids in small to medium industrial tanks. Its compact size allows for unobtrusive installation in process areas with limited real estate, offering a reliable alternative to contact-based level sensors.

Problem Solved

Provides accurate and durable liquid level monitoring in challenging industrial environments where space is restricted or where contact with the liquid is undesirable.

3. End-of-Travel Position Sensing for Miniature Actuators

The robust IP67 construction and compact form factor (8.2 x 19 x 10.5 mm) make the EX-22B-PN ideal for reliably determining the end-of-travel position of miniature pneumatic or electric actuators. It can be integrated directly into the actuator's housing or mounted in extremely tight spots to confirm full extension or retraction of machine components, even in environments with dust or water splashes.

Problem Solved

Ensures precise and reliable position feedback for miniature linear or rotary actuators in industrial machinery operating in potentially harsh conditions.
