Hinged Door
• If the Switch is mounted too close to the hinge, the force imposed
on the lock will be much larger than for locations far from the hinge
and the lock may be damaged. Mount the Switch close to the
handle.
Mounting
Appropriate Tightening Torque
Loose screws may result in malfunction. Tighten the screws to the
specified torques.
Switch and Operation Key Mounting
• Mount the Switch and Operation Key securely to the applicable
tightening torque with M4 screws. Always use washers.
• The switch can be fastened more firmly by a stud (4 mm dia., 1.5
mm max height) inserted from back side at the hole of the switch.
• Do not impose excessive force on the key top while the operation
key is inserted into the switch body or drop the switch with the
operation key inserted to avoid the deformation of the key or the
breakage of the switch body.
• Do not use the operation key other than dedicated OMRON's
(D4SL-NK@). Otherwise switch may be damaged.
• Do not use the operation key D4SL-K@. A lock will not be closed
and a machine will not be activated.
• Be sure that the operation key can be inserted properly to key hole
with a tolerance of ±0.8 mm.
• Insert the operation key into the key hole according to the specified
“operation key insertion radius in horizontal direction”.
• When mounting at the side of switch body, mount the switch with 3
points including the head.
• Attach cap heads to any operation key holes that are not being
used.
Securing the Door
When the door is closed (with the
Operation Key inserted), the Operation
Key may exceed the set zone because
of, for example, the door's own weight,
machine vibration, or the door cushion
rubber.
Secure the door with a stopper (hook)
so that the Operation Key remains
within the set zone.
Spacer
Do not remove a spacer. Rotate the spacer in accordance with the
Switch mounting direction. Use of the Switch without spacer will
reduce the lock strength.
Wiring
Circuit Connection Example
• Direct opening contacts used as safety-circuit inputs are indicated
with the mark.
• DC solenoids have polarity. (E1: +, E2: −) Confirm terminal polarity
before wiring.
• The current of the 24 VDC solenoid is different from when it is first
turned ON as to when it is in operation. To take into account
possible voltage drops, it is important to apply a rated operation
voltage.
• To enable the 24 VDC solenoid, it is necessary to select the
appropriate power supply capacity.
• The ON and OFF contact operation will not engage
simultaneously.
Be sure to confirm operation under actual operating conditions.
• If a lock is required for safety, design the system so that the closing
of the NC contacts on both the door open/closed detection switch
and the lock monitor switch is detected.
(D4SL-N@N@@-D@)
Contacts 12 and 41 and contacts 22 and 51 are internally connected.
(D4SL-N@SF@-@)
There is no internal connection, so connect contacts 22 and 42 or 21
and 42 externally.
