World's smallest Class 6-contact Guard Lock
Safety-door Switch
<Guard Lock Safety-door Switch D4SL-N>
• Wiring time is reduced with two types of wiring
methods capable of one-touch attachment and
removal.
• A wide variety of built-in switches can be used for
various devices.
(4-, 5-, and 6-contact models are available)
• Key holding force of 1,300 N.
• It is possible to change the key insertion point
without detaching the head.
• Drive solenoids directly from the Controller.
<Slide Key D4SL-NSK10-LK@>
• Lockout Key to prevent workers from becoming
trapped inside the hazardous area.
• The vertical D4SL Guard Lock Safety-door Switch
can be easily mounted on 40 × 40 mm aluminum
frames.
• The plastic material makes the Slide Key suitable
for lightweight doors.

D4SL-N@@@G-@ (Solenoid Lock Models)
Door open/closed detection and lock monitor contacts: Can be used in safety circuits because of the direct opening mechanisms.
Door open/closed detection contact: Can be used to confirm whether the key is inserted and to monitor the open/closed status of a door.
Lock monitor contact: Can be used to confirm whether power is supplied to the solenoid and to monitor whether or not a door can be opened or closed.
Note: 1. The door open/closed detection and lock monitor contact configuration depends on the model.
2. If a current is detected in the solenoid lock model, before the door is closed, the door will remain unlocked.
Be sure to supply power to the solenoid after the door is closed.

Characteristics
Note: 1. The above values are initial values.
2. The Switch contacts can be used with either standard loads or microloads.
Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads.
The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced.
*1. The degree of protection is tested using the method specified by the standard (EN60947-5-1).
Confirm that sealing properties are sufficient for the operating conditions and environment beforehand.
Although the switch box is protected from dust, oil or water penetration, do not use the D4SL in places where cutting chips, oil, water or
chemicals may enter through the key hole on the head, otherwise Switch damage or malfunctioning may occur.
*2. The durability is for an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. For more details, consult your OMRON
representative.
*3. Do not pass the 1 A, 125 VAC load through more than 3 circuits.
*4. These figures are minimum requirements for safe operation.
*5. This figure is based on the GS-ET-19 evaluation method.
*6. This value will vary with the switching frequency, environment, and reliability level.
Confirm that correct operation is possible with the actual load beforehand.

Note: The numbers in boxes are the terminal numbers given on the Switch.
Circuit Connection Example
•Direct opening contacts used as safety-circuit input are indicated with the mark.
•Do not switch circuits for three or more standard loads at the same time.
Doing so may adversely affect insulation performance.
•DC solenoids have polarity. (E1: Positive, E2: Negative)
Confirm terminal polarity before wiring.
•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.
Connection Example for D4SL-N@AF@-@
Contacts 12 and 41 are internally connected.
Connection Example for D4SL-N@EF@-D@
Contacts 12 and 41 are internally connected.
Connection Example for D4SL-N@SF@-@
There is no internal connection, so connect contacts 22 and 42 or 21
and 42 externally.
Connection Example for D4SL-N@NF@-D@
Contacts 12 and 41 and contacts 22 and 51 are internally connected.
