Guard Lock Safety-door Switch
D4JL
World's Top* Holding Force of 3,000 N
*For plastic models, as of May 2008
Two safety circuits and two monitor contacts provide an
array of monitoring patterns.
Standard gold-clad contacts enable use with ordinary loads
and microloads.
Models with trapped keys prevent workers from being locked
in hazardous work areas.
Models with rear release buttons allow people to unlock the
Switch and escape if they are locked into hazardous areas.
IP67 degree of protection
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 5 for a list of models.)
OMRON also offers Trapped Key Switches (on mechanical lock
models only).
As long as a person has the trapped key when he enters a hazardous
area, he does not have to worry about somebody locking the door and
trapping him inside.
The door can be opened only by supplying power to the solenoid and
then turning the trapped key to unlock the D4JL.
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
(See page 4 for a list of models.)
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. Refer to the “D4NS-SK/D4JL-SK”
for details.
Be sure to read the “Safety Precautions” on page 21 and the
“Precautions for All Safety Door Switches”.
