Industrial Applications

1. Automated Conveyor Belt Object Detection

Accurately detecting the presence or absence of diverse objects on an industrial conveyor belt, regardless of their color or the background conveyor material, to ensure proper item sorting or processing.

Problem Solved

The background suppression feature and 5-350mm detection range allow reliable detection of objects (even with varying reflectivity) without false triggers from the conveyor belt itself. The fast 1ms response time and 500Hz switching frequency are critical for high-speed lines. The IP67 rating protects against dust and occasional splashes in manufacturing environments.

2. Small Part Assembly Verification in Robotics

Verifying the correct placement or presence of small components within tight spaces during automated assembly processes using robotic arms.

Problem Solved

The miniature design (1.1x3.1x2.0 cm) enables integration into robotic end-effectors or confined assembly jigs. The precise 5-350mm detection range allows for accurate positioning and presence checks of small parts. The 10-30V DC operation is standard for robot controllers, and the PNP output integrates easily.

3. Door/Gate Position Sensing in Harsh Environments

Monitoring the open/closed status of industrial doors or safety gates in dusty or humid factory settings, ensuring personnel safety and process control.

Problem Solved

The robust IP67 degree of protection ensures reliable operation in environments with dust, splashing water, or high humidity. The wide operating temperature range (-30 to 60 °C) allows for use in unheated warehouses or areas with temperature fluctuations. The visible red light spot simplifies alignment during installation.
