Locking safety door switch
November 4, 2007

Omron’s IP67-rated D4JL guard locking safety door switch provides 674 lbs. of holding force. Two safety circuits and two monitor contacts provide a variety of monitoring patterns, while standard gold-clad contacts enable use with microloads and ordinary loads. The switch is available with rear release buttons that allow workers to unlock the switch from inside a protected area and exit the hazardous areas.
