Safety Door

Switches

Solenoid Lock Models

The solenoid lock locks the door only when power is supplied to the

solenoid. Therefore, the door will be unlocked if the power supply to

the solenoid stops. Therefore, do not use solenoid lock models for

machines that may be operating and dangerous even after the

machine stops operating.

Switch and Operation Key Mounting

Mount the D4BL and Operation Key with four M5 screws with

washers and tighten each screw to the specified torque.

Operation Key

The D4BL is provided with a shock-absorbing damper to protect the

D4BL from damage that may result from dropping the D4BL during

transportation. Be sure to remove the damper after mounting the

D4BL.

The mounting tolerance of the Operation Key is

±0.3 mm vertically or

horizontally. Be sure to mount the D4BL correctly without leaning,

otherwise the D4BL may soon break or wear out.

Observe the specified insertion radius for the Operation Key and

insert it in a direction perpendicular to the key hole.

The Operation Key for the D4BL is different from the one for the

D4BS.

Head Direction

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.
