LMS-K500ML (Inline CO2 Laser Marker / Supports EMS, ODM for various small quantities and customer-specific traceability)

last updated：Jul 31, 2026

Horiuchi Electronics Co., Ltd. Development Division

Minimize setup changes and ensure reliable history management for each customer. One unit to be integrated into the contract manufacturing line.

In contract manufacturing (EMS/ODM), the need for quick changeovers between different product types and the ability to meet varying traceability requirements from customers are both required simultaneously for low-volume, high-variety production. The LMS-K500ML is a CO2 laser marker that is integrated inline into the assembly line, marking a unique ID non-contact for each circuit board, supporting history management across different product types and customers. 【Usage Scenarios】 - Quickly implement product changeovers in low-volume, high-variety production through program calls. - Assign unique IDs to circuit boards in customer-specific and product-specific formats for separate history management. - Comply with SMEMA for inline integration, executing printing and reading verification without manual intervention. 【Benefits of Implementation】 - Reduce the effort and errors associated with setup changes, maintaining operational efficiency even with small lots and diverse products. - Flexibly respond to traceability requirements from each customer with a single device. - Achieve labor savings through inline integration while ensuring quality in contract manufacturing.
