Industrial Applications

1. Precision Small Part Detection for Robotic Assembly

The ultra-compact size (1.8 x 1.6 x 0.45 cm) and a sensing range of 2-25mm make the EX-24B ideal for detecting very small components, such as chip components or tiny screws, in the confined spaces of robotic grippers or feeders.

Problem Solved

Ensures accurate presence/absence detection of miniature parts, preventing assembly errors and improving throughput in high-density automated manufacturing where space is critical.

2. Micro-Sensing for Wafer Protrusion in Semiconductor Manufacturing

With its clear red LED beam spot and ability to detect objects down to 0.1mm diameter at 10mm setting distance, the EX-24B is perfectly suited for checking for slight protrusions or misalignments of delicate wafers within semiconductor processing machinery where space is extremely limited and precision is paramount.

Problem Solved

Guarantees the integrity and proper positioning of wafers, crucial for preventing damage and maintaining quality in sensitive semiconductor fabrication processes requiring micro-detection capabilities.

3. Reliable Object Presence Detection in Wet Industrial Machinery

With its robust IP67 rating, the EX-24B can be deployed in environments subject to washdowns, coolant splashes, or high humidity, such as food processing lines or machine tool applications, to reliably detect objects passing through a small opening or at a short distance.

Problem Solved

Provides dependable operation and prevents false detections in challenging industrial settings where sensors are exposed to water and other liquids, extending sensor lifespan and reducing downtime, supported by its 12-24VDC supply and 0.5ms response.
