The A-LAS-CON1-FIO / FIO-4/20 is a high-speed analog laser control unit designed to operate with up to two optical fibers from the FIO Series, offering precision object detection, tolerance band monitoring, and micron-level positioning or thickness control. It features a scan frequency up to 25 kHz, a high-resolution 12-bit A/D converter, and analog outputs of either 0–10V or 4–20mA, making it suitable for dynamic industrial measurement applications. The unit is configurable via Windows® software (A-LAS-CON1-Scope), supports digital I/O, and allows external teaching and tolerance adjustment through built-in controls or RS232/USB/Ethernet interface. With its IP54-rated blue anodized aluminum housing and flexible fiber optic options, it performs well even in challenging environments where dust accumulation or mechanical stress may be present. Typical applications include 100% inspection of parts, position or edge detection, thickness control, and gloss or surface evaluation in high-speed production lines or quality assurance stations. Its compatibility with a wide variety of optical frontends and mounting fixtures expands its versatility across automotive, packaging, electronics, and materials processing sectors.
