OMRON D4N specification

last update: September 24, 2012

Characteristics

Degree of protection *1		IP67 (EN60947-5-1)
Durability *2	Mechanical	15,000,000 operations min. *5
	Electrical	500,000 operations min. (3 A resistive load at 250 VAC) *3 300,000 operations min. (10 A resistive load at 250 VAC)
Operating speed		1 to 500 mm/s (D4N-1120)
Operating frequency		30 operations/minute max.
Contact resistance		25 mΩ max.
Minimum applicable load *4		1 mA resistive load at 5 VDC (N-level reference value)
Rated insulation voltage (Ui)		300 V
Rated frequency		50/60 Hz
Protection against electric shock		Class II (double insulation)
Pollution degree (operating environment)		3 (EN60947-5-1)
Impulse withstand voltage (EN60947-5-1)	Between terminals of same polarity	2.5 kV
	Between terminals of different polarity	4 kV
	Between each terminal and non- current carrying metallic parts	6 kV
Insulation resistance		100 MΩ min.
Contact gap		Snap-action: 2 × 0.5 mm min. Slow-action: 2 × 2 mm min.
Vibration resistance	Malfunction	10 to 55 Hz, 0.75 mm single amplitude
Shock resistance	Destruction	1,000 m/s2 min.
	Malfunction	300 m/s2 min.
Conditional short-circuit current		100 A (EN60947-5-1)
Conventional free air thermal current (Ith)		10 A (EN60947-5-1)
Ambient operating temperature		-30 to 70°C (with no icing)
Ambient operating humidity		95% max.
Weight		Approx. 82 g (D4N-1120) Approx. 99 g (D4N-6120)

Note: 1. The above values are initial values.
           2. 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.
