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 D4BS in places where dust, 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%. Contact your OMRON sales representative for more detailed information on other operating environments. *3. These figures are minimum requirements for safe operation. 3 D4BS Structure and Nomenclature Structure Head The switch head is coated with easy-to-see red paint. The mounting direction of the switch head can be varied to any of the four directions. Operation Key D4BS's exclusive-use Operation Key is provided to assure accurate switching operation. Seal Ring (NBR) Set Zone Mark A triangular Set Zone Mark makes it easy to adjust the operating position when inserting the Operation Key. Oil Seal (NBR) The operation plunger employs an oil seal, with which the switch box meets the requirements of IP67. Built-in Switch A shearing force contact separating mechanism (NC contact) is employed, which positively pulls apart the contacts from each other by using shearing force if any abnormality such as contact welding should occur in the contact area. There is a difference in level between the NC and NO terminal, which assures easy wiring. Seal Packing (NBR) Conduit Opening Refer to the following list.

Precautions for Safe Use • Do not use the Switch submersed 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. (The IP67 degree of protection of the Switch specifies the amount of water penetration after the Switch is submerged in water for a certain 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. Stopper Installation Do not use a Switch as a stopper. Be sure to install a stopper as shown in the following illustration when mounting the Switch and adjust the stopper so that the Operation Key is within the setting zone. Do not subject the Switch to a shock that exceeds the Switch's shock resistance of 1,000 m/s2. Stopper Correct Extra space Incorrect Precautions for Correct Use Appropriate Tightening Torque Loose screws may result in malfunction. Tighten the screws to the specified torques. Type Appropriate tightening torque M3.5 terminal screw (including ground terminal screw) 0.59 to 0.78 N·m Cover mounting screw 1.18 to 1.37 N·m Head mounting screw 0.78 to 0.98 N·m M5 body mounting screw * 4.90 to 5.88 N·m Operation Key mounting screw 2.35 to 2.75 N·m Connector 1.77 to 2.16 N·m Cap screw 1.27 to 1.67 N·m *Apply a torque of 4.90 to 5.88 N·m for an Allen-head bolt. For a pan head screw, apply a torque of 2.35 to 2.75 N·m.

To ensure safety, use screws that cannot be easily removed or another means to prevent the Switch and Operation Key from easily being removed. 7 D4BS Operation Key Wiring Make sure that the Operation Key can be inserted properly with a tolerance of ±0.5 mm in the upward, downward, left, or right direction. Otherwise the D4BS may soon become damaged due to misalignment. Do not connect the lead wires directly to the terminals. Connect the lead wires through insulation tubes and M3.5 round crimp terminals. Tighten each terminal screw within the proper torque range. The proper lead wire is AWG20 to AWG14 (0.5 to 2.5 mm2) in size. Observe the specified insertion radius for the Operation Key and insert it in a direction perpendicular to the key hole. Do not use the D4BL operation key. Incorrect ±0.5 or greater dz dia.: D dia.: B: L: F: I: Incorrect ±0.5 or greater 3.7 4.5 7.0 20.2 7.7 9.0 (mm) D dia. dz dia. Wire using the methods shown below so that the crimp terminals are not caught on the case or cover. Otherwise it may not be possible to mount the cover completely and malfunctions may occur. Changes in Head Mounting Direction By removing the screws on the four corners of the head, the head can be reset in any of four directions. The head direction can be changed with or without the Operation Key inserted in the head. Make sure that no foreign materials enter through the head and that the head is tightened securely within the proper torque range. Incorrect Correct Terminal screw Crimp terminal Incorrect Correct Terminal screw Terminal screw Crimp terminal Cover Cover Casing Casing Crimp terminal Correct Incorrect Crimp terminal Crimp terminal Conduit Opening • Tighten the connector to a suitable torque. • Excessive tightening torque may damage the casing. • If using a Pg13.5 conduit, use an ABS-08 Pg13.5 connector or an ABS-12 Pg13.5 connector (manufactured by Nippon Flex). • Use a connector (SC Series, sold separately) suitable for the outer diameter of the cable. 8 Terms and Conditions Agreement Read and understand this catalog.
