Safety Limit Switch D4B-@N CSM_D4B-_N_DS_E_5_1 Snap-action contact with certified direct opening operation certification . Maintenance, seal, and resistance to shock increased and direct opening mechanism added. Three-conduit switches and 2NC switches are also available. Note: Contact your sales representative for details on models with safety standard certification. • Direct opening mechanism (NC contacts only) added to enable opening contacts when faults occur, such as fused contacts. • Safety of lever settings ensured using a mechanism that engages a gear between the operating position indicator plate and the lever. • Equipped with a mechanism that indicates the applicable operating zone, as well as push-button switching to control left and right motion. • Head seal structure strengthened to improve seal properties (TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13). • Wide standard operating temperature range: –40 to 80°C (standard type). • Models with gold-plated contacts added to the series to enable handling microloads. • Certified standards: UL, CSA, EN (TÜV), and CCC.

The D4B-0006N Adjustable Roller Lever and D4B-0007N Adjustable Rod Lever, however, cannot be used. Do not order them for a Side Rotary Operating Head. 13 D4B-@N Application Precaution Changing the Operating Direction Operating section (on back of Head) Switches with Roller Levers The operating direction of the lever can be easily changed without using any tools. It can be set to clockwise operation (CW) or counterclockwise (CCW) operation. Use the procedure given at the right to change the operating direction. Operating procedure 1. Remove the four Head set screws and remove the Head from the Switch Box. Head Cover Operating position mark (arrow) 2. Turn the bottom of the Head toward you, press in the Head Cover shown in the diagram at the left, and turn the Cover clockwise or counterclockwise. Note: The factory setting is for “CW.CCW.” 3. The “CW” setting is for clockwise operation and the “CCW” setting is for counterclockwise operation. Set the Cover to the desired position. Safety Precautions Refer to the “Precautions for All Switches” and “Precautions for All Safety Limit Switches”. Mounting Precautions for Safe Use • 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. Use four M5 screws with washers to mount the standard model. Be sure to apply the proper torque to tighten each screw. The 3-conduit models can be mounted more securely by using the four screws plus two 5 −0.05 −0.15 mm diameter studs, each of which has a maximum height of 4.8 mm as shown below. Mounting Dimensions (M5) Standard Model 3-conduit Model Precautions for Correct Use Appropriate Tightening Torque (3) 60 (4) 30 (1) 1 M3.5 terminal screw (2) Appropriate tightening torque 0.59 to 0.78 N·m 2 Cover mounting screw * 1.18 to 1.37 N·m 3 Head mounting screw 0.78 to 0.88 N·m 4 M5 body mounting screw 4.90 to 5.88 N·m 5 Connector 1.77 to 2.16 N·m Lever Mounting Screws (Roller 6 4.90 to 5.88 N·m Levers) --- Cap screw (for three-conduit models) 5−0.05 −0.15 dia. height: 5 max. Changes in Actuator Mounting Position (5) Type 30 40 42 Studs 27±0.1 (6) Be sure to tighten each screw of the D4B-@N properly, otherwise the D4B-@N may malfunction. 59.3±0.1 1.27 to 1.67 N·m • To change the angle of the lever, loosen the Allen-head bolts on the side of the lever. • The operating position indicator plate * has protruding parts which engage with the lever, thus allowing changes to the lever position by 90°. • The back of the operating position indicator plate * has no protruding parts. If this plate is turned over and attached, any angle within a 360° range can be set. Do not turn over the plate, however, when using the D4B-@N as a switch with a certified direct opening mechanism. For an SUVA- or BIA-certified application, make sure that the lever engages with the operating position indicator plate securely so that the lever will not slip. * The operating position indicator plate: Refer to page 7. Changes in Head Mounting Position By removing the screws on the four corners of the head, the head can be reset in any of four directions. Make sure that no foreign materials will penetrate through the head. * Apply a tightening torque of 0.78 to 0.88 N·m to three-conduit models. 14 D4B-@N Wiring Conduit Opening Do not connect the bare lead wires directly to the terminals but be sure to connect each of them by using an insulation tube and M3.5 round crimp terminals and tighten each terminal screw within the specified torque range. The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm2) in size. dz dia.: D dia.: B: L: F: l: 3.7 mm 4.5 mm 7.0 mm 20.2 mm D dia. 7.7 mm 9.0 mm dz dia. Make sure that all crimp terminals come into contact with the casing or cover as shown below, otherwise the cover may not be mounted properly or the D4B-@N may malfunction. Correct Incorrect Terminal screw • Make sure that each connector is tightened within the specified torque range. The casing may be damaged if the connector is tightened excessively. • If the 1/2-14NPT is used, cover the cable and conduit end with sealing tape in order to ensure IP67. • The Pg13.5 connector must be Nippon Flex’s ABS-08 Pg13.5 or ABS-12 Pg13.5. • Use an OMRON SC-series Connector (sold separately) that is suited to the cable in diameter. • Properly attach the provided conduit cap to the unused conduit opening and securely tighten the cap screw within the specified torque when wiring the D4B-@N. Others • The load for the actuator (roller) of the Switch must be imposed on the actuator in the horizontal direction, otherwise the actuator or the rotating axis may be deformed or damaged. Correct Incorrect Dog Dog Crimp terminal Incorrect Correct Terminal screw Terminal screw Crimp terminal Cover Cover Casing Crimp terminal Casing • When using a long lever model like the D4B-@@16N or D4B-@@17N, the Switch may telegraph. To avoid telegraphing, take the following precautions. 1. Set the lever to operate in one direction. 2. Modify the rear end of the dog to an angle of 15° to 30° as shown below or to a secondary-degree curve. θ θ Correct 15° ≤ θ ≤ 30° θ ≥ 30° 3. Modify the circuit so as not to detect the wrong operating signals. Crimp terminal Incorrect Crimp terminal Ordering Method The D4B-@N uses a block mounting method. Switches can be ordered either as sets or as individual parts. If a set is ordered, the Switch will be shipped with all parts assembled. Individual model numbers Set model number Example: D4B-2111N Switch Box + D4B-2100N + Head D4B-0010N + + Lever * D4B-0001N Note: For Switches with Roller Levers, do not order just the Head and Lever, or just the Switch Box and Lever. *Roller Levers only. 15 Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
