Industrial Applications

1. High-Speed Small Part Detection on Conveyor Belts

The EX-19B's ultra-slim design and 0.5ms response time enable accurate, high-speed detection of small components (min. ø2.0mm) on production lines. Its 1-meter range is ideal for conveyor widths, and the NPN output integrates easily with PLC systems, while IP67 ensures reliable operation in typical industrial environments where dust or splashes might occur.

Problem Solved

Ensures precise and rapid counting or positioning of small objects without impeding conveyor flow or requiring large sensor mounting space.

2. Robotic Gripper Finger Presence Sensing

With its minuscule 3.5mm thickness and 19x10mm footprint, the EX-19B can be directly integrated into robotic gripper fingers or end-effectors to detect the presence or absence of small parts. The 12-24VDC operating voltage is standard for robotics, and the IP67 rating protects against minor contamination during material handling operations.

Problem Solved

Provides reliable feedback to robot controllers for successful part gripping, preventing 'air picks' or damage to components due to misaligned or absent parts, without adding significant bulk to the gripper.

3. Compact Machine Door/Guard Interlock Monitoring

The EX-19B's thrubeam sensing mode and 1-meter range provide a robust solution for monitoring the closure of small machine doors or safety guards. Its compact size allows for unobtrusive installation, and the NPN output can signal a safe state to a machine control system. The IP67 rating ensures longevity even with exposure to coolants or cleaning agents.

Problem Solved

Provides a space-efficient and reliable safety interlock, ensuring machinery cannot operate if a protective guard or door is open, thus enhancing operator safety in tight machinery designs.
