The D4JL offers two safety circuits and two monitor contacts, optional trapped keys to prevent workers from being locked in hazardous areas and rear release buttons to allow people to unlock the switch and escape if they are locked into hazardous areas. In addition, the D4JL series offers IP67 protection, led indicators, and mounting slides key.
