Safety Components is a subcategory of hardware elements related to the functional and operational safety of robotic systems. It encompasses E-stop modules, safety relays, circuit breakers, protective circuits, interlocks, and other components that limit the risk of failure or accident. These elements are relevant across industrial, service, and mobile robotics.

A Safety Relay is an electrical component used to monitor safety circuits such as e-stops, light curtains, door interlocks, and machine safety signals. In robotics and industrial automation, safety relays play an important role in ensuring controlled shutdown and safe system states. They are designed to meet functional safety requirements and high reliability standards.
