6 d4n characteristics 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). confir m that sealing properties ar e sufficient for the operating conditions and environment beforehand. although the switch box is protected from dust or water penetration, do no t use the d4n in places where foreign material such as dust, dirt, oil, water, or chemicals may penetrate through the head. otherwise, accele rated 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 t hat correct operation is possib le with the actual load beforehand. *5. the mechanical durability of fork lever lock models is 10,000,000 operations min. degree of protection * 1 ip67 (en60947-5-1) durability * 2 mechanical 15,000,000 operations min. * 5 electrical 500,000 operations min.

18 d4n safety precautions refer to the precautions for all switches and precautions for all safety limit switches. ! caution ? do not use the switch submerged in oil or water, or in locations continuously subject to splashes of oil or water. doing so may result in oil or water entering the switch interior. (the ip67 degree of protection specification for the switch refers to water penetration while the switch is submersed in water for a specified period of time.) ? always attach the cover after completing wiring and before using the switch. also, do not turn on the switch with the cover open. doing so may result in electric shock. ? do not switch circuits for two or more standard loads (250 vac, 3 a). doing so may adversely affect insulation performance. 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 smalle r loads may be reduced. mounting method appropriate tightening torque tighten each of the screws to the specified torque. loose screws may result in malfunction of the switch within a short time. switch mounting ? mount the switch using m4 screws and spring washers and tighten the screws to the specified torque. ? for safety, use screws that cannot be easily removed, or use an equivalent measure to ensure that the switch is secure. ? as shown below, two studs with a maximum height of 4.8 mm and a diameter of 4 mm can be provided, the studs inserted into the holes on the bottom of the switch, and the switch secured at four locations to increase the mounting strength. switch mounting holes ? make sure that the dog contacts the actuator at a right angle. applying a load to the switch actuator (roller) on a slant may result in deformation or damage of the actuator or rotary shaft. electric shock may occasionally occur. do not use metal connecto rs or metal conduits. precautions for safe use precautions for correct use 1 terminal screw 0.6 to 0.8 nm 2 cover mounting screw 0.5 to 0.7 nm 3 head mounting screw 0.5 to 0.6 nm 4 lever mounting screw 1.6 to 1.8 nm 5 body mounting screw 0.5 to 0.7 nm 6 connector, m12 adaptor 1.8 to 2.2 nm (except 1/2-14npt) 1.4 to 1.8 nm (for 1/2-14npt) 7 cap screw 1.3 to 1.7 nm 7 6 3 4 5 1 2 one-conduit type two-conduit type ? 0.05 ? 0.15 2.5 0.1 22 0.1 47 0.1 20 0.1 22 0.1 two, m4 ? 0.15 4 ? 0.05 dia. height: 4.8 max. 42 0.1 39 0.1 20 0.1 22 0.1 40 0.1 42 0.1 2.5 0.1 5.35 0.1 two, m4 ? 0.15 4 ? 0.05 dia. height: 4.8 max. dog dog correct incorrect

[reference] the crimp terminals shown below are not more than 0.5 mm thick. contact arrangement ? the contact arrangements are shown below. screw terminal type connector type ? applicable socket: xs2f-d421 series (omron). ? refer to the connector catalog for details on socket pin numbers and lead wire colors. socket tightening (connector type) ? turn the socket connector screws by hand and tighten until no space remains between the socket and the plug. ? make sure that the socket connector is tightened securely. otherwise, the rated degree of protection (ip67) may not be maintained and vibration may loosen the socket connector. conduit opening ? connect a recommended connector to the opening of the conduit and tighten the connector to the specified torque. the case may be damaged if an excessive ti ghtening torque is applied. ? when using 1/2-14npt, wind sealing tape around the joint between the connector and conduit opening so that the enclosure will conform to ip67. ? use a cable with a suitable diameter for the connector. ? attach and tighten a conduit cap to the unused conduit opening when wiring. 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 us ed 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. t he 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. manufacturer type j.s.t. mfg. co. fn0.5-3.7 (f type) n0.5-3.7 (straight type) 22 21 34 33 12 11 a a c e b d f c e b d f 28 mm tolerance 2 mm 33 mm 42 mm 22 21 34 33 12 11 a c e b d f a c e bdf 28 mm tolerance 2 mm left hand 42 mm a c e bdf 28 mm tolerance 2 mm right hand 42 mm l l f b d dia. dz dia. correct incorrect terminal screw crimp terminal t: 0.5 mm dz dia.: 3.7 mm d dia.: 2.9 mm b: 6.6 mm l: 19 mm f: 7.7 mm i : 8.0 mm 14 32 13 31 d4n- @ d @@ (3nc) 11 21 12 22 31 32 d4n- @ b @@ (2nc) d4n- @ 2 @@ (2nc (snap)) 11 31 12 32 d4n- @ c @@ (2nc/1no) d4n- @ f @@ (2nc/1no (mbb)) d4n- @ a @@ (1nc/1no) d4n- @ e @@ (1nc/1no (mbb)) 33 34 11 21 12 22 11 33 12 34 d4n- @ 1 @@ (1nc/1no (snap)) 14 (4) 32 (2) (3) 13 (1) 31 1 3 24 pin no.
