The Protector is ATI Industrial Automation's patented robotic collision sensor designed to prevent costly damage to robotic end-effectors resulting from robot crashes. The Protector's features include: automatic reset, high repeatability, large moment rotation, rugged design and low cost.

The automatic reset feature particularly benefits workplace safety. After the robot crashes, ATI's collision sensor will automatically reset when the robot removes the tooling from the crash-causing object and when torsional rotation does not exceed 20-25 degrees.

Compliant in the X, Y and Z axes, this capability provides a safer method for resetting by making it unnecessary for personnel to enter the robotic work cell.

Along with the Protector’s superior angular compliance, a spring option provides three different breakaway moment settings. This feature provides additional compliance when a low moment trip point is needed. Pneumatic pressure can be added to increase moment capacity for high-inertia motions, and the pressure can be released—relying on the spring alone for low-inertia moves.
