Are You Ready? WEEE Directive Full Implementation Starts 15-Aug-18

Trapped Key Interlocking

Many machine design­ers think of inter­locks as exclu­sive­ly elec­tri­cal devices; a switch is attached to a mov­able mechan­i­cal guard, and the switch is con­nect­ed to the con­trol sys­tem. Trapped Key Inter­lock­ing is a way to inter­lock guards that is equal­ly effec­tive, and often more appro­pri­ate in dif­fi­cult envi­ron­men­tal con­di­tions.

How to Apply a Safety Edge to a Machine Guard — Part 3: Stopping Performance

In Part 2 of this arti­cle, I looked at the pres­sure-sen­si­tive devices (safe­ty edges) them­selves. This part explores the stop­ping per­for­mance require­ments that engi­neers and tech­nol­o­gists need to con­sid­er when apply­ing these devices.
