D4BS G-145 Nomenclature 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. Set Zone Mark A triangular Set Zone Mark makes it easy to adjust the operating position when inserting the Operation Key. Seal Ring (NBR) Oil Seal (NBR) The operation plunger employs an oil seal, with which the switch box meets the requirements of IP67 (the sealing capability of the Operation Key's insertion mouth is IP00). 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. Seal Packing (NBR) Conduit Opening Available in four different types of conduit threads: Pg 13.5, G1/2, or 1/2-14NPT, M20. There is a difference in level between the NC and NO terminal, which assures easy wiring. Ground Terminal Screw A ground terminal is provided to improve safety. (Built into the Unit.)

G-148 Safety Sensors / Components Precautions Do not dismount the Operation Key from the door intentionally and insert it to the Switch with the door open. Machine may start operating and injury or death may be caused. Mount the Operation Key at a location where it will not come in contact with users when the door is opened or closed. When operating the D4BS as a part of a safety category circuit to prevent injury, operate the NC contacts that have a direct opening mechanism in direct opening mode. For safety purposes, tighten the switch body and Operation Key with one-way screws or equivalents or install a switch protection cover and warning label for safety purposes to prevent easy removal of the D4BS. Securing the Door If the Operation Key on the closed door is pulled outside the set zone by a force caused by vibration, the door's weight, or the door cushion rubber, the switch contact may be opened (causing the machinery to stop) or the D4BS may be damaged. Secure the door with hooks so that it will remain within the set zone. Extra space Connect the fuse to the D4BS in series to prevent it from short-circuit damage. The value of the breaking current of the fuse must be calculated by multiplying rated current by 150% to 200%. When using the D4BS with EN ratings, use 10-A fuse Type gI or gG that complies with IEC60269. Set zone Correct Use Operating Environment Make sure in advance that the environment is suitable, with no oil, water, or chemicals, as these may cause the seal to deteriorate, resulting in faulty contact, faulty isolation, current leakage, or burning. Do not use the D4BS in the following locations: * * * * Locations subject to severe temperature changes Locations subject to high temperatures or condensation Locations subject to severe vibration Locations where the product may come into direct contact with processing waste or dust Mounting Do not use the Switch as a stopper. Be sure to install a stopper as shown in the following illustration when mounting the Switch. The range of space "a" must be determined according to the available set zone of the Operation Key. Stopper a Operation Key Be sure to use a special Operation Key only. Do not operate the D4BS with anything other than the special Operation Key, otherwise the D4BS may break or the safety of the system may not be maintained. Switch Do not impose excessive force on the Operation Key inserted into the D4BS or drop the D4BS with the Operation Key inserted, otherwise the Operation Key may deform or break. Refer to Dimensions for the mounting dimension of the Operation Key and mount the Operation Key correctly. The Operation Key will soon become damaged or worn out if it is not mounted correctly. Excessive force 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. 0.5 min. Drop Secure the Operation Key with a one-way screw, or an equivalent, so that the Operation Key cannot be easily removed. 0.5 min. D4BS G-149 Other Mounting Dimensions (M5) Make sure that the D4BS is located outside the safety door and that no metal dust, oil, or chemical will be sprayed onto the D4BS. Otherwise, the D4BS may soon fail to operate due to the penetration of metal dust, oil, or chemical. Standard Model Three-conduit Model 30 40 42 Tightening Torque Be sure to tighten each screw of the D4BS properly, otherwise the D4BS may malfunction. 59.30.1 60 Protruding portions 270.1 30 5 -0.05 -0.15 dia. holes, max. height 5 Mounting hole Mounting side Insertion hole for protrusions -0.05 dia. holes, max. height 5 5-0.15 No. 1 2 3 4 5 6 7 Type M3.5 terminal screw (including ground terminal screw) Cover mounting screw (see note 1) Head mounting screw M5 body mounting screw (see note 2) Operation Key mounting screw Connector Cap screw Torque 0.59 to 0.78 N*m The D4BS can be mounted more securely by adding two protruding portions, each of which is 5 mm maximum in height and 5 -0.05/-0.15 mm in diameter as shown below.

Apply a torque of 0.78 o 0.88 N*m if the D4BS is a three-conduit model. 2. Apply a torque of 4.90 to 5.88 N*m in the case of an Allenhead bolt. If it is a pan head screw, apply a torque of 2.35 to 2.75 N*m. Vertical Mounting Two, M5 400.1 Adjustable Mounting (Horizontal) Two, M5 300.1 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 penetrate through the head and that the head is tightened securely within the proper torque range. G-150 Safety Sensors / Components Wiring Connector Do not connect the lead wires directly to the terminals. Connect the lead wires through insulation tubes and M3.5 crimp terminals. Tighten each terminal screw within the proper torque range. Tighten the connector to a suitable torque. Excessive tightening torque may damage the casing. The proper lead wire is AWG20 to AWG14 (0.5 to 2.5 mm2) in size. dz dia.: D dia.: B: L: F: I: 3.7 4.5 7.0 20.2 7.7 9.0 (mm) When using a 1/2-14NPT conduit, apply sealing tape between connector and conduit opening so that the enclosure will confirm to IP67. 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. When wiring a 3-conduit model, securely tighten the cap screw provided for unused conduit openings.
