Oil Seal (NBR) Conduit Opening Ground Terminal Screw Seal Ring (NBR) Seal Packing (NBR) D4BS's exclusive-use Operation Key is provided to assure accurate switching operation. A triangular Set Zone Mark makes it easy to adjust the operating position when inserting the Operation Key. 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. A ground terminal is provided to improve safety. (Built into the Unit.) Available in four different types of conduit threads: Pg 13.5, G1/2, or 1/2-14NPT, M20. 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). 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.

D-110 Safety Sensors / Components Precautions Caution Do not dismount the Operation Key from the door intentionally and insert it to the Switch with the door open. Machine may start oper- ating and injury or death may be caused. Mount the Operation Key at a location where it will not come in con- tact 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 pur- poses to prevent easy removal of the D4BS. 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 calcu- lated 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. Correct Use Operating Environment Make sure in advance that the environment is suitable, with no oil, water, or chemicals, as these ma y cause the seal to deteriorate, resulting in faulty contact, faulty is olation, current leakage, or burn- ing. 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 pro- cessing waste or dust 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 main- tained. Do not impose excessive force on the Operation Key inserted into the D4BS or drop the D4BS with the Operation Key inserted, other- wise the Operation Key may deform or break. Secure the Operation Key with a one-way screw, or an equivalent, so that the Operation Key cannot be easily removed. 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. 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. 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. Make sure that the Operation Key can be inserted properly with a tol- erance of ±0.5 mm in the upward, downward, left, or right direction, otherwise the D4BS may soon become damaged. Excessive force Drop Extra space Set zone a Stopper Switch ±0.5 min. ±0.5 min.

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. Other- wise, the D4BS may soon fail to operate due to the penetration of metal dust, oil, or chemical. Tightening Torque Be sure to tighten each screw of the D4BS properly, otherwise the D4BS may malfunction. Note: 1. Apply a torque of 0.78 o 0.88 N·m if the D4BS is a three-con- duit model. 2. Apply a torque of 4.90 to 5.88 N·m in the case of an Allen- head bolt. If it is a pan head screw, apply a torque of 2.35 to 2.75 N·m. Mounting Dimensions (M5) The D4BS can be mounted more securely by adding two protruding portions, each of which is 5 mm maximum in height and –0.05/–0.15 mm in diameter as shown below. Operating Key Mounting Dimensions 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.

D-112 Safety Sensors / Components Wiring 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. The proper lead wire is AWG20 to AWG14 (0.5 to 2.5 mm 2) in size. Make sure that all crimp terminals are correctly connected and located within the casing or cover as shown below. Connector Tighten the connector to a suitable torque. Excessive tightening torque may damage the casing. When using a 1/2-14NPT conduit, apply sealing tape between con- nector 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, se curely tighten the cap screw pro- vided for unused conduit openings.
