Plastic Locking
Safety-door Switches Rank Among the Strongest in the World
A
holding force of 3,000 N makes these Switches suitable for large, heavy
doors.
Models with Trapped Keys
OMRON also offers Trapped Key Switches (on mechanical lock models only).
The door can be opened only by supplying power to the solenoid to release
the trapped key lock and then turning and removing the trapped key. As
long as a person has the trapped key when he enters a hazardous area, he
cannot be accidentally locked inside by someone else. A trapped key also
serves to prevent someone from forgetting the key when entering a
hazardous area because the trapped key must be removed to open the door.
There are thirty different types of trapped keys available for use in
applications with adjacent hazardous areas.
Two Safety Circuits and Two
Monitor Contacts
The D4JL has two safety circuits. It also has two contacts to separately
monitor the open/closed status of the door and the status of the lock.
Models with Rear Release
Buttons
A Switch with a rear release button allows
the door to be unlocked from inside a hazardous area in an emergency.
OMRON also offers Switches with Special Slide Keys.
