Guard Lock Safety-door Switch
D4BL
Protective Doors Are
Locked Until Machines
Completely Stop Operating
• A mechanical lock is applied automatically when the
Operation Key is inserted. A high level of safety is
achieved using a mechanism where the lock is only
released when voltage is applied to the solenoid.
• Conforms to EN (TÜV) standards corresponding to
the CE marking.
• Approved by UL, CSA, BIA, and SUVA standards.
• The switch contact is opened by a direct opening
mechanism (NC contacts only) when the protective
cover is opened. Direct opening mechanism that is
EN-approved is indicated by on the switch.
• Auxiliary release key ensures easy maintenance and
unlocks the door in the case of a power failure.
• Tough aluminum die-cast body incorporating a
switch box with degree of protection satisfying IP67,
UL, and CSA TYPE6P, 13.
• Equipped with a horizontal and vertical conduit open-
ing.
• Models incorporating easy-to-see indicators for mon-
itoring and those using an adjustable Operation Key
for a double door are available.
• The mounting direction of the head can be changed
to allow the Operation Key to be inserted from four di-
rections.
• Metric conduit types available

Circuit Connection Example
• Do not connect the indicators to the safety contact terminals (11-
12-31-32) or the safety circuit side.
• When using indicators, connect them to the auxiliary circuit side
(monitor circuit) or the solenoid input terminals as shown below.
• The indicators can be used to confirm the open/closed status of the
door, the ON/OFF status of the power supply, and the ON/OFF sta-
tus of the solenoid.

• Do not connect the indicators in parallel with the direct opening
contact. If the indicators are broken, a short-circuit current may
flow, causing equipment to malfunction.
• The 24-VDC solenoid terminals have polarity. Confirm the polarity
before wiring.
• Be sure to use a special pushbutton switch to stop and start
machinery and release locks.

Head Directions
The head can be mounted in four directions. To remove the head,
turn the head by 45° as shown in figures A and B below.
To change the direction of the head, make sure that the protruding
part of the rotating lever engages with the groove of the plunger.
Then turn the head clockwise or counterclockwise to the desired
direction. At that time, make sure that the groove of the plunger is
located under the rotating lever. If the direction of the head is not set
when the plunger is rotated by 45°, the groove of the plunger presses
the rotating lever. The head, plunger, or the built-in switch may be
damaged as a result.

Be sure to check the mechanical lock and solenoid release functions
when mounting the D4BL.
If the head direction is changed, recheck the tightening torque of
each of screw. Make sure that no foreign materials will penetrate
through the key hole on the head.
Mounting the Cover
When tightening the cover, first check the specified torque, and then
tighten each screw to the that torque. Also, make sure that no foreign
matter has entered the switch.
When mounting the cover, make sure that the cover and switch box
are properly aligned.
