Space Sensor: 3D Sensing with Ease and Affordability
SpaceSensor mounting examples


SpaceAge Control's compact SpaceSensor 3D displacement sensor uses a retractable displacement cable to measure 3-dimensional coordinates, distances, and angles over a 13-foot (3.96 m) radius (longer radii are optionally available). With the Space Sensor 3D displacement sensor, expensive, cumbersome, or immobile fixtures and mounts are a thing of the past.

Designed for OEM applications in quantities of 10 ore more, raw sensing is performed using a patented 2-axis gimbal head with three high-resolution encoders as inputs into a powerful microcontroller-based signal conditioner. Repeatability is better than 0.05% of the operating radius.
