An industrial brake is not smart\u2014it opens and closes based on physics. To make it part of an automated system (PLC), you need eyes on it. That\u2019s the job of limit switches<\/strong>. They tell the crane control system “I am open, safe to lift” or “I am closed, motor off.”<\/p>\n\n\n\n

However, limit switches are the #1 cause of nuisance faults in brake systems. A loose bracket or a wrong wiring logic can stop a critical production line.
