M12-connector models are available, saving on labor and simplifying replace- ment.  Standardized gold-clad contacts provide high contact reliability.  Applicable to both standard loads and micro loads.  Free of lead, cadmium, and hexavalent chrome, reducing the burden on the en- vironment.

Weight Approx. 96 g (D4NS-1CF) 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 rough- ening of the contact surface and contact reliability may be lost. 3. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are suffi- cient for the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do not use the D4NS in places where foreign material may penetrate through the key hole on the head, otherwise Switch damage or mal- functioning may occur. 4. The durability is for an ambient temperature of 5° C to 35° C and an ambient humidity of 40% to 70%. For more details, consult your OMRON representative. 5. If the ambient temperature is greater than 35° C, do not pass the 3-A, 250-VAC load through more than 2 circuits. 6. These figures are minimum requirements for safe operation. 7. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the ac- tual load beforehand.

Suitable socket is Type XS2F (OMRON).  Please do a regular check in premeditation for this switch. 7. Socket tightening (connector type) Do not use any tools, such as pliers, otherwise the socket connector may become damaged. Connect the socket connector to the connector threads of the D4NS. Then firmly turn the socket connector by hand so that the connector threaded portion will be completely covered by the socket connector so that space will be almost 0. Make sure, however, that the socket connector is tightened securely, otherwise the rated degree of protection of the D4NS may not be maintained. Furthermore, the socket connector may be loosened by vibration. D4NS G-139 D4NS F502-EN2-04.book Seite 140 Dienstag, 26.

List of Recommended Substitute Products Date of Production Termination Switch Production of the D4DS Series will be terminated in July 2006. D4DS product Recommended substitute product D4DS-15FS D4NS-1AF Date of Substitute Product Release D4DS-25FS D4NS-2AF Sale of the D4NS Series commenced in July 2003. D4DS-35FS D4NS-3AF Product Replacement D4DS-55FS D4NS-5AF D4DS-65FS D4NS-6AF 1. Dimensions D4DS-1AFS D4NS-1BF The D4DS and D4NS have basically the same structure, and use the same mounting method, Operation Keys, mounting hole and Operation Key D4DS-2AFS D4NS-2BF insertion positions. The multi-contact structure and the extra 4 mm in D4DS-3AFS D4NS-3BF length, however, are different. 2. Terminal Numbers D4DS-5AFS D4NS-5BF For the 2-contact model, the terminals 21, 22, 23, and 24 on the D4DS are D4DS-6AFS D4NS-6BF 31, 32, 33, and 34 on the D4NS. 3. Recommended Terminals If the recommended terminals are not used, the Switch may not be Operation Key compatible. Make sure that the Switch is compatible with the terminals.

Juli 2005 5:48 17 !WARNING This catalog is a guide to help customers select the proper safety product. Observe the following items when choosing products, select the right product for your device or equipment, and develop a safety-related system to fully utilize the product's functions. Setting up a risk assessment system The items listed in this catalog must be used properly in terms of product location as well as product performance and functionality. Part of the process of selecting and using these products should include the introduction and development of a risk assessment system early in the design development stage to help identify potential dangers in your equipment that will optimize safety product selection. A badly designed risk assessment system often results in poor choices when it comes to safety products.  Related international standard: ISO 14121 "Principles of risk assessment." Safety policy When developing a safety system for the devices and equipment that use safety products, make every effort to understand and conform to the entire series of international and industrial standards available, such as the examples given below.  Related international standards: ISO/DIS 12100 "Basic concepts, general principles for design" IEC 61508 "Functional safety of electrical/electronic/programmable electronic safety-related systems." Role of safety products Safety products have functions and mechanisms that ensure safety as defined by standards. These functions and mechanisms are designed to attain their full potential within safety-related systems. Make sure you fully understand all functions and mechanisms, and use that understanding to develop systems that will ensure optimal usage.  Related international standard: ISO 14119 "Interlocking devices associated with guards- Principles for design and selection." Installing safety products Make sure that properly educated and trained engineers are selected to develop your safety-related system and to install safety products in devices and equipment.  Related international standards: ISO/DIS 12100 "Basic Concepts, general principles for design." IEC 61508 "Functional safety of electrical/electronic/programmable electronic safety-related systems." Observing laws and regulations Safety products should conform to pertinent laws, regulations and standards, but make sure that they are used in accordance with the laws, regulations and standards of the country where the devices and equipment incorporating these products are distributed.  Related international standard: IEC 60204 "Electrical equipment of machines." Observing usage precautions Carefully read the specifications and precautions listed in this catalog for your product as well as all items in the Operating Manual packed with the product to learn usage procedures that will optimize your choice. Any deviation from precautions will lead to unexpected device or equipment failure not anticipated by safety-related systems or fire originating from equipment failure. Transferring devices and equipment When transferring devices and equipment, be sure to keep one copy of the Operating Manual and pack another copy with the device or equipment so the person receiving it will have no problem operating it.
