Features
Plastic Guard Lock 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
(See page 55 for a list of models.)
OMRON also offers Trapped Key Switches (on mechanical lock
models only). The door can be opened only by supplying power to
the solenoid and then turning the trapped key to unlock the D4JL. As
long as a person has the trapped key when he enters a hazardous
area, he cannot be accidentally locked inside by someone else.
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.
