OMRON switch key, D4SL-NK5

• Combining compact size and convenience, enabling safety for numerous devices

• Solenoid current 0.2A

• 0.26A for 6-contact type

• Solenoid current for electromagnetic locking: 0.2A for 4-contact and 5-contact types, and 0.26A for 6-contact type.
  

• Direct connection to the controller is possible without the need for relays, reducing costs and space requirements.

• Compared to our previous products, the D4SL-N achieves a compact size of approximately 28% for the terminal block type and approximately 38% for the connector type. This significantly improves ease of use. It can be installed in a 40mm aluminum frame without being exposed.

• Previously, when rotating the head during horizontal installation, it was necessary to reset it after removing the head. However, with the D4SL-N, rotation is achieved simply by rotating the head pad with a finger, greatly reducing operation time.

• The D4SL-N is available in both connector and terminal block types. Both types feature one-touch assembly and disassembly of the body and wiring, greatly improving operability during installation and maintenance efficiency.

• Small and slim, yet achieving a locking strength of 1300N.
  

• 30% stronger than our previous product (D4GL), ensuring reliable performance in applications requiring strong switching.

• A wide variety of Omron electromagnetic locking safety door switches

• D4SL-N utilizes a wide insertion port and a wide guide port to absorb loosening.

• The upper and lower parts of the insertion port can be fixed with screws, thus suppressing positional deviation of the switch body.

• Uses a metal head (optional) to reduce wear and damage caused by loosening during insertion.

• The cross-shaped release key's operating part is made of metal, improving durability for repeated operation during maintenance.

• Note

• The above values ​​are initial values.
  

• The switch contacts are shared by general loads and small loads. Do not connect a smaller load to contacts that have previously been switched with a load. Otherwise, the contact surface will become rough, reducing contact reliability.
  

• The values measured by this protective structure are based on the test methods specified in standard (EN60947-5-1). Please confirm the sealing performance beforehand according to the actual usage environment and conditions.

  The switch box body can prevent the ingress of dust or water, but please ensure that there are no foreign objects such as chips, oil, water, or medicines entering the key socket on the head. Otherwise, it may lead to premature wear, damage, or malfunction.

• The durability conditions are for use at an ambient temperature of 5–35℃ and an ambient humidity of 40–70%RH. Please consult for other detailed conditions.
  

• Do not connect more than 3 circuits simultaneously to AC125V 1A.
  

• For safe use, please be sure to comply with this condition.
  

• Evaluation method based on ISO 14119.
  

• This value may vary depending on switching frequency, environmental conditions, reliability level, etc. Please confirm with actual load beforehand.

Note. In the operating key outline drawing, the tolerance for dimensions not specified is ±0.4mm.
