“Safety Components on Guard”, a new white paper from AutomationDirect, focuses on protecting operators of machine and robot installations. The paper encompasses pneumatics, safety switches, interlock safety switches, non-contact switches, safety limit switches, and safety light curtains, mats, and edges. Illustrated text describes how these components are integrated through safety relays or controllers to put a machine into a safe state. Of particular interest is a photo showing the safeguarding needs of a robotic work cell. It demonstrates the use of a variety of safety components to protect workers while still allowing access for maintenance and repairs. This whitepaper can be downloaded at bit.ly/HP1910Paper.
