39、witchgear and Controlgear Part 5-2: Control Circuit Devices and Switching Elements Proximity Switches. It is the rst edition of CAN/CSA-C22.2 No. 60947-5-2, and the third edition of UL 60947-5-2. This standard is based on IEC 60947-5-2, Edition 2.2, which is based on the second edition (1997), and i

40、ts amendment 1 (1999) and its amendment 2 (2003). This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Industrial Control Equipment, of the Council on the Harmonization of Electrotechnical Sta

41、ndards of the Nations of the Americas (CANENA), are gratefully acknowledged. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This standard was reviewed by the CSA Integrated Committee on Industrial Control, under the jurisdiction of the

42、 CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved as a National Standard of Canada by the Standards Council of Canada (SCC). Th

43、is standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Application of Standard Where reference is made to a specic number of samples to be tested, the specied number is considered a minimum quantity. Note: Although the intended primary app

44、lication of this Standard is stated in its scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. This CAN/CSA-C22.2 No. 60947-5-2, Standard for Safety for Low-Voltage Switchgear and Controlgear Part 5-2:

45、Control Circuit Devices and Switching Elements Proximity Switches, is to be used in conjunction with the second edition of CAN/CSA-C22.2 No. 60947-1. The requirements for proximity switches are contained in this Part 2 Standard and CAN/CSA-C22.2 No. 60947-1. UL Standard 60947-5-2, Standard for Safet

46、y for Low-Voltage Switchgear and Controlgear Part 5-2: Control Circuit Devices and Switching Elements Proximity Switches, is to be used in conjunction with the fth edition of UL 60947-1. The requirements for proximity switches are contained in this Part 2 Standard and UL 60947-1. Requirements of thi

47、s Part 2 Standard, where stated, amend the requirements of CAN/CSA-C22.2 No. 60947-1. Requirements of this Part 2 Standard, where stated, amend the requirements of UL 60947-1. Where a particular subclause of CAN/CSA-C22.2 No. 60947-1 is not mentioned in 60947-5-2, the CAN/CSA-C22.2 No. 60947-1 subcl

48、ause applies. Where a particular subclause of UL 60947-1 is not mentioned in 60947-5-2, the UL 60947-1 subclause applies.
