Overview
The Siko DA04-3404 is a mechanical-digital position indicator engineered for precise measurement and display of rotational position on machinery spindles, adjustment axes, and drive shafts. This is a basic device with 4 decades, offering reliable counting without electronics or power requirements. Ideal for production environments where position verification must occur directly at the point of adjustment.
