Infographic: 9 Common Machine Safety Devices

A safety controller monitors multiple safety and non-safety input devices, providing safe stop and start functions for machines with hazardous motion. A single safety controller can replace multiple safety relay modules in applications that include E-Stop buttons, safety light curtains, interlocking gate switches, and other safety input devices.

By requiring that a machine operator use both hands to initiate and continue a machine cycle, two-hand control devices keep the operator at a safe distance from the hazardous motion of the machine. If one or both hands are removed from the device, the machine de-energizes, bringing the hazardous motion to a stop.

Safety laser scanners protect personnel and equipment within a user designated area. These flexible safety solutions are ideal for safeguarding complex and irregularly shaped areas and mobile assets that cannot be easily solved using other safeguarding solutions.

Safety interlock switches monitor the mechanical guards that separate an individual from a hazard. If a guard, like a gate, door, or panel is opened or removed, the safety interlock switches send a signal to the machine control system to halt the hazardous situation.

Visible from all angles, over long distances, and in bright conditions, modular tower lights provide real-time machine or safety status indication. These customizable, high-visibility indicators have options for AC and DC supply power, single and multicolor segments as well as audible modules.

Emergency stop devices allow workers to quickly stop a device by pushing a button or pulling a rope in order to prevent injury to personnel and material loss. These devices are wired to override all other machine controls and remove power from hazardous machine motion.
