Magnetic Scale Read Head | Application in Laser Marking Machines

Laser marking machines use high-energy laser beams to mark surfaces across industries like electronics, automotive and medical. As laser technology evolves, selecting a precise read head for displacement control is essential to improve stability and reduce costs.

1. Company

A Shenzhen customer manufactures laser equipment and required high-precision, high-speed and stable read heads to support marking complex-shaped products.

2. Background

To mark a complex “projection necklace” product, the marking machine must quickly and accurately identify and position parts. Any positioning error causes inaccurate marks and significant loss.

3. Pain points

Positioning varied shapes and sizes is difficult; drift and accumulated errors during processing make precise marking challenging.

4. Solution

The customer selected the Atonm MH0-H500 magnetic scale read head to address positioning. Atonm magnetic scales achieve ±30μm/m accuracy and deliver high-speed, high-resolution displacement detection using magnetic ruler technology, offering compact structure and strong interference resistance.

The read head provides long life, high reliability and easy installation, reducing maintenance and replacement costs and improving economic efficiency.

5. Benefits

1. Increases marking precision and stability.

2. High-speed scanning increases marking throughput.

3. Long life and reliability reduce costs and maintenance efforts.
