Once a contact has been used to switch a standard load, it cannot be used for a load of a smaller capacity. Doing so may result in roughening of the contact surface and contact reliability may be lost. *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 or water penetration, do not use the D4N in places where foreign material such as dust, dirt, oil, water, or chemicals may penetrate through the head. Otherwise, accelerated wear, 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 3 A, 250 VAC load through more than 2 circuits. *4. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual load beforehand. *5. The mechanical durability of fork lever lock models is 10,000,000 operations min. 6 D4N Structure and Nomenclature Structure Safety-oriented Lever Setting (Form-lock construction) Head Grooves which engage the lever are cut in the lever and The direction of the switch head can be varied to any of rotary shaft to prevent the lever from slipping against the the four directions.

Tighten the conduit cap to the specified torque. The conduit cap is provided with the Switch (2-conduit types). Changing the Lever The lever mounting screws can be used to set the lever position to any position in a 360° angle at 7.5° increments. Grooves are incised on the lever and rotary shaft that engage to prevent the lever from slipping against the rotary shaft. The screws on adjustable roller lever models can also loosened to change the length of the lever. Remove the screws from the front of the lever before mounting the lever in reverse (front/back), and set the level so that operation will be completed before exceeding a range of 180° on the horizontal. 18 D4N Recommended Connectors Use connectors with screws not exceeding 9 mm, otherwise the screws will protrude into the case interior, interfering with other components in the case.

If the cover is attached with the seal rubber out of place or if foreign material is stuck to the rubber, a proper seal will not be obtained. • Do not use any screws to connect the cover other than the specified ones. The seal characteristics may be reduced. • Make sure that foreign particles do not enter the head when removing the screws from the four corners to change the head position in any of the four directions. • Use the following recommended countermeasures to prevent telegraphing when using adjustable or long levers. 1. Make the rear edge of the dog smooth with an angle of 15° to 30° or make it in the shape of a quadratic curve. 2. Design the circuit so that no error signal will be generated. 19 Terms and Conditions Agreement Read and understand this catalog.
